Electrical testing, LVD

J.S. Hamilton is a well-known and recognized laboratory that performs tests of low-voltage equipment and products that meet the requirements of the Low Voltage Directive (LVD) (2014/35/EU) and harmonized standards.

We perform tests for the following series of standards:

  • PN-EN 60204 (IEC 60204) – a standard concerning the safety of electrical equipment of machines. Its main objective is to ensure that the design, installation and maintenance of electrical systems in industrial machines comply with safety regulations to protect people and property from electrical hazards.
  • PN-EN 62208 (IEC 62208) – a standard that specifies general technical and testing requirements for empty enclosures intended for the installation of low-voltage switchgear and controlgear assemblies. Its purpose is to ensure that enclosures supplied by manufacturers are safe and meet criteria that will enable the subsequent construction of a complete, standard-compliant switchgear assembly.
  • PN-EN IEC 61439 – the standard specifies requirements for low-voltage switchgear and controlgear assemblies. Its purpose is to ensure the safety, reliability, and durability of these devices. This series replaced the earlier EN 60439 standard and introduced key changes, especially in the areas of responsibility and verification.
  • PN-EN 60598 (IEC 60598) – a series of European and international standards (as IEC 60598) that regulate the safety requirements for lighting fixtures.

Its primary purpose is to ensure that lamps, luminaires, and other lighting devices are safe to use and do not pose a risk of electric shock, fire, or other hazards.

  • PN-EN 60335 (IEC 60335) – a key series of European standards that regulate the safe use of household and similar electrical appliances. Its primary purpose is to protect users, including children and the elderly, from hazards such as electric shock, fire, burns, and mechanical hazards.
  • PN-EN IEC 62368 – a standard regarding the safety of audiovisual, information technology and telecommunications (ICT) devices. It replaced the older, more complex EN 60950-1 (for IT equipment) and EN 60065 (for audiovisual equipment) standards with a modern, risk-based approach to safety engineering.
  • PN-EN 61851 – a key set of European and international standards (similar to
    IEC 61851) that defines electrical safety requirements for electric vehicle (EV) charging systems. Its primary goal is to ensure the safety of the charging process for the user, the vehicle, and the surrounding environment.
  • PN-EN 60601 (IEC 60601) – a standard that specifies safety requirements and essential technical parameters for medical electrical equipment. Its primary goal is to ensure that medical devices are safe for patients, operators, and other persons during normal use and in the event of a single fault.
  • EN 62841 (IEC 62841) is a key series of European and international standards that defines safety requirements for handheld, portable, and lawn and garden power tools. Its primary purpose is to ensure the safety of these tools for users by preventing electric shock, fire, and mechanical injury. This standard largely replaced the older EN 60745 and EN 61029 standards.

Compliance with the Low Voltage Directive (LVD) 2014/35/EU, is mandatory for all electrical products covered by its scope that are placed on the European Union market.

Conformity Assessment Process

This process is called conformity assessment, for which the manufacturer is fully responsible. It involves several key steps:

  • Preparation of technical documentation: The manufacturer must collect and prepare documents demonstrating that the product meets safety requirements.
    This documentation should include, among other things, test results, technical drawings, and a risk analysis.
  • Issuance of the EU Declaration of Conformity: This is a written statement by the manufacturer declaring that their product complies with all applicable EU directives.
  • CE Marking: Once the declaration has been issued, the manufacturer can affix the CE mark to the product, providing a visible confirmation of compliance.

The Role of Notified Bodies

Although the entire process is the responsibility of the manufacturer, in some cases they may utilize the services of a notified or certification body. However, this is not mandatory under the LVD Directive. The manufacturer can commission independent tests to confirm compliance with standards (e.g., the EN 60335 series), which facilitates the creation of technical documentation and reduces the risk of introducing a dangerous product to the market.

PN-EN 60204 (IEC 60204)

The purpose of this standard is to ensure that electrical systems in machines are safe, reliable, and easy to operate. EN 60204-1 (general part) applies to a wide range of machines, from simple machine tools to complex production lines. The standard covers the entire life cycle of a machine, from design and installation to testing, maintenance and repair.

The PN-EN 60204-1 standard focuses on several key areas:

  • Power and disconnection: Requires that each machine must have a visible, easily accessible power disconnect device that can be locked in the “off” position (e.g., a main switch).
  • Protection against electric shock: Defines methods of protection against contact with live parts (insulation, grounding, use of low voltage).
  • Control and safety functions: Requires the use of an emergency stop button (E-stop) and other functions that ensure the safe stopping of the machine in a hazardous situation.
  • Technical documentation: Requires manufacturers to prepare detailed documentation, including electrical diagrams, drawings, technical specifications, and operating instructions.
  • Marking and identification: Specifies the rules for labeling cables, terminals and devices, facilitating safe installation, service, and maintenance.

Relationship to the Machinery Directive

The PN-EN 60204-1 standard is harmonized with the Machinery Directive 2006/42/EC. This means that meeting its requirements gives the manufacturer a presumption of conformity with the essential safety requirements of this directive. This is a key step in the conformity assessment process, which allows the machine to be legally placed on the market and CE marked.

EN 62208 (IEC 62208)

This standard focuses on verifying the design and material characteristics of empty enclosures to safely protect the equipment contained within.

Key areas assessed include:

  • IP Protection Rating: According to EN 60529, enclosures must provide adequate protection against the ingress of solid objects and water. For example, an enclosure with an IP65 rating is completely dust-tight and protected against water jets.
  • Mechanical Impact Resistance (IK): The standard requires enclosures to be tested for impact resistance in accordance with EN 62262, ensuring their durability in harsh environments.
  • Material Properties: Materials are tested for their resistance to corrosion, UV radiation, and flammability.
  • Protective circuit continuity: In the case of metal enclosures, the standard requires ensuring an adequate electrical connection between all parts, which is crucial for effective grounding and protection against electric shock.

All of the above tests are accredited to the AB1552 standard performed by the J.S. Hamilton Laboratory.

The PN-EN 62208 standard is closely related to the PN-EN 61439 series of standards, which apply to complete switchboards. Compliance of the empty enclosure with PN-EN 62208 is a prerequisite for building a complete switchboard, which must then meet the requirements of PN-EN 61439. In short, PN-EN 62208 ensures the quality and safety of the “enclosure” in which the electrical components will be housed.

EN IEC 61439

The EN IEC 61439 series of standards consists of a general part and several specific parts, which are always used together:

  • EN IEC 61439-1 (General rules): This is a basic document that contains definitions, verification principles, and general requirements applicable to all types of switchgear.
  • EN IEC 61439-2 (Switchgear and controlgear for power distribution): Applies to switchgear and controlgear assemblies used in industry and buildings for the distribution of electrical energy.
  • EN IEC 61439-3 (Distribution boards intended for use by lay persons): Specifies requirements for switchgear that is accessible to ordinary users, e.g., in residential buildings.
  • EN IEC 61439-5 (Low-voltage switchgear and controlgear assemblies for the distribution of electrical energy in public networks). The EN 61439-5 standard applies to assemblies used in public power networks, outdoor installations (e.g., street lighting poles, distribution poles), and indoor installations (e.g., substations in public buildings). These assemblies are used to distribute electricity, control street lighting, and protect equipment in public places.

The most significant change introduced by the 61439 series compared to previous standards is the shift from the concept of “type-test” to design verification. This means that the manufacturer must prove the compliance of the switchgear through a series of tests, calculations, and design checks.

Key areas of verification include:

  • Temperature rise: Testing whether the temperature inside the switchgear does not exceed permissible limits.
  • Short-circuit current withstand: Verification that the switchgear will withstand the dynamic and thermal forces generated during a short circuit.
  • IP rating: Confirmation that the enclosure provides adequate protection against solid objects and water. Compliance with the PN-EN IEC 61439 standard is crucial for manufacturers, as it provides a presumption of conformity with the Low Voltage Directive (LVD) and allows for the legal introduction of a product onto the EU market with the CE marking. In addition to performing the above tests, JS Hamilton also offers certification performed by our PCA-accredited certification body.

EN 60598 (IEC 60598)

Like many other product safety standards, the EN 60598 series (luminaires) is divided into two main parts, which must always be used together:

EN 60598-1 (General requirements): This part contains fundamental requirements and test procedures that apply to all types of luminaires. It addresses aspects such as:

  • The device is exposed to moisture (e.g., by dousing it with water), and its electrical parameters are then assessed to ensure it does not pose a hazard.

EN IEC 62368

The main innovation of the standard is its approach based on hazard-based safety engineering (HBSE). Unlike previous standards, which focused on specific, detailed design requirements, EN IEC 62368 focuses on three key steps:

  • Identification of energy sources: Locating all energy sources in the product that could be harmful to users. This includes electrical, thermal, kinetic, chemical, and radiant energy.
  • Classification of energy sources: These sources are classified into three levels (ES1, ES2, ES3) based on their potential harmfulness.
  • Implementation of safeguards: Implementation of appropriate protective mechanisms to prevent the transfer of harmful energy to the user.

Flexibility: HBSE gives manufacturers greater design freedom, allowing them to implement innovative solutions, provided their safety is proven.
Compliance with PN-EN IEC 62368 is crucial for electronics manufacturers, as it allows them to legally place products on the EU market and mark them with the CE mark. This standard is harmonized with the Low Voltage Directive (LVD), meaning that compliance with it provides a presumption of conformity with the directive’s requirements.

The tests specified in the IEC 62368 standard include:

  • Identification and classification of energy sources: The first step is to identify all energy sources in the product (electrical, thermal, mechanical, radiant) and assign them a class (ES1, ES2, ES3) based on their potential harmfulness.
  • Assessment of protective barriers: Verification of whether barriers (e.g., insulation, enclosure, safety switches) are sufficient to protect against classified energy sources. These tests include:
  • Dielectric strength tests: A test involving the application of a high voltage to the insulation to ensure there is no breakdown, which could cause electric shock.
  • Clearance and leakage current measurements: Verification of whether the distances between current-carrying parts are sufficient to prevent shock.
  • Impact and mechanical strength tests: Verification of whether the product enclosure is resistant to damage that could expose hazardous parts.
  • Thermal Tests:
  • Temperature Rise Measurement: The device operates under normal and emergency conditions, and the temperature on its surfaces and internal surfaces is measured to ensure it does not reach dangerous levels that could cause burns or fire.
  • Material Flammability Tests: Glow-wire tests assess the resistance of materials to ignition.
  • Power Supply Tests:
  • Internal Power Supply Test: Verification of the safety of power supply circuits, including batteries and internal power supplies.

Corrosion is a gradual degradation process affecting materials, particularly metals and their alloys. Exposure to atmospheric conditions such as salt mist and humidity results in rust formation, which deteriorates mechanical properties and reduces product lifespan. Therefore, implementing and validating effective anti-corrosion protection is crucial.

Accelerated corrosion testing allows verification of protective coating systems. At J.S. Hamilton, we conduct corrosion tests in accordance with the following standards:

  • PN-EN ISO 9227 – Corrosion tests in artificial atmospheres: Salt spray tests,
  • PN-EN ISO 6270-1 – Paints and varnishes: Determination of resistance to humidity – Part 1: Condensation,
  • PN-EN ISO 6270-2 – Paints and varnishes: Determination of resistance to humidity – Part 2: Water condensation exposure in heated water tank chambers,
  • PN-EN ISO 12944 series – Paints and varnishes: Corrosion protection of steel structures by protective paint systems,
  • PN-EN ISO 11997-1 – Paints and varnishes: Determination of resistance to cyclic corrosion conditions – Part 1: Wet (salt fog) / dry / humid cycles.
  • PN-EN IEC 60068-2-11 – Environmental testing — Part 2-11: Tests — Test Ka: Salt mist
  • PN-EN IEC 60068-2-52 – Environmental testing — Part 2: Tests — Test Kb: Cyclic salt mist (sodium chloride solution)

PN-EN ISO 9227

This standard allows assessment of corrosion resistance for metallic materials with protective coatings, as well as detection of discontinuities, pores, and damage in organic and inorganic coatings. It enables quality control and comparison of coating processes across production batches.

Depending on the protective system applied, the following tests are conducted:

  • NSS (Neutral Salt Spray) – suitable for metals, metallic coatings (anodic and cathodic), conversion coatings, anodic oxide coatings, and organic coatings,
  • AASS (Acetic Acid Salt Spray) – suitable for decorative coatings such as copper + nickel + chromium or nickel + chromium, and anodic or organic coatings on aluminum,
  • CASS (Copper-Accelerated Acetic Acid Salt Spray) – also used for decorative coatings on aluminum with copper acceleration.

Our salt spray chambers are regularly calibrated in accordance with PN-EN ISO 9227 to ensure repeatability and reproducibility of test results.

Test duration is determined based on material specifications and agreed with the client. Key test parameters verified every 24 hours (excluding weekends) include:

  • Temperature: NSS and AASS at 35°C; CASS at 50°C,
  • Sodium chloride concentration: 50 g/l ± 5 g/l,
  • Collection rate: 1.5 ml/h ± 0.5 ml/h for an 80 cm² horizontal surface,
  • pH of solution: NSS – 6.5 to 7.2; AASS and CASS – 3.1 to 3.3,
  • Visual inspection – first signs of corrosion.

This is intended to regulate parameters such as the solution’s pH and to ensure full control over the proper course of the examination. After testing, samples are cleaned and evaluated based on client-specific criteria.

PN-EN ISO 6270-2

The ISO 6270-2 standard is used for testing coated samples in an atmosphere with constant or cyclic condensation in order to ensure the verification of repeatable test results performed in different laboratories.
This testing method aims to evaluate the behaviour of test samples in a humid atmosphere and to detect any deficiencies in the corrosion protection of the test specimens. However, testing of coatings in such atmospheres does not necessarily provide data for predicting a service life.
After conditioning, the test samples are evaluated against standards, such as the relevant parts of the ISO 4628, or according to the agreed procedures.

PN-EN ISO 12944

Uncoated steel corrodes in water, soil, and atmospheric conditions. Therefore, to prevent its degradation, steel structures are coated with appropriate protective layers designed to protect them during a specified exposure period.
The methods described in those standards concern the protection of steel structures using paint systems. There are nine parts of the ISO 12944:

  1. General introduction
  2. Environmental classification
  3. Design considerations
  4. Surface preparation
  5. Protective paint systems
  6. Laboratory test methods
  7. Execution and supervision of painting work
  8. Specifications for new projects and maintenance
  9. Systems and lab methods for offshore and related structures

PN-EN ISO 12944-1 specifies the durability of the protective layer in four periods:

Classification
PL DE EN
L krótki kurz low up to 7 years
M średni mittel medium 7-15 years
H długi lang high 15-25 years
VH bardzo długi sehr lang very high over 25 years

It should be noted that the durability period is not the same as the warranty period. Durability can help the manufacturer to establish a maintenance or renovation plan. The warranty period is usually shorter than the durability period.

PN-EN ISO 12944-2 classifies environments into categories of atmospheric corrosivity (C1 – very low, C2 – low, C3 – medium, C4 – high, C5-I – very high industrial, C5-M – very high marine), as well as soil and water (Im1 – fresh water, Im2 – sea or brackish water, Im3 – soil).

Corrosivity categories of the atmosphere and examples of typical environments according to EN ISO 12944-2:2017
Corrosivity categories Typical environments Corrosivity categories impact
C1 Heated buildings with a clean atmosphere, e.g. offices, shops, schools, hotels very low impact
C2 Slightly polluted atmospheres: mainly rural areas. Unheated buildings where condensation can occur, e.g. warehouses, sports halls. low impact
C3 Urban and industrial atmospheres, medium sulfur dioxide pollution: coastal areas with low salinity. Production rooms with high humidity and some air pollution, such as food plants, laundries, breweries, dairies. medium impact
C4 Industrial areas and coastal areas with moderate salinity. Chemical plants, swimming pools, ship and boat repair yards. high impact
C5 Industrial areas with high humidity and aggressive atmosphere and coastal areas with high salinity. Buildings or areas with almost continuous condensation and high pollution. very high
CX Offshore areas with high salinity and industrial areas with extreme humidity and aggressive atmospheres, as well as subtropical and tropical atmospheres. extreme

 

PN-EN ISO 12944-6 defines testing methods based on durability periods and corrosivity categories for paint systems. Detailed information regarding the duration of the tests and the test regime can be found in section 5.6 Test procedures and duration of testing of this part of the standard.

For example, if the tested elements fall under corrosivity category C2 and the desired durability is very high, then according to test regime 1, the samples must undergo a water condensation test according to PN-EN ISO 6270-1 (240 hours), and a neutral salt spray test according to PN-EN ISO 9227 (480 hours). These tests must be conducted using separate sets of test panels.

The samples are then evaluated according to the following standards:

  • PN-EN ISO 2409: Cross-cut test – for protective layers up to 250 µm thick;
  • PN-EN ISO 4628-2: Assessment of degree of blistering;
  • PN-EN ISO 4628-3: Assessment of degree of rusting;
  • PN-EN ISO 4628-4: Assessment of degree of cracking;
  • PN-EN ISO 4628-5: Assessment of degree of flaking;
  • A.2: Corrosion in the scribe after neutral salt spray testing;
  • A.2: Corrosion in the scribe after cyclic aging testing;
  • and verification for compliance with the requirements set out in section 6: Assessment of the paint system.

EN IEC 60068-2-11 Standard

EN 60068-2-11 standard covers environmental testing. It focuses on assessing the corrosion resistance of components, equipment, and materials in salt spray environments.

Main Objectives and Characteristics:

  • Salt spray test. This is a standardized test method designed to accelerate the corrosion process in laboratory conditions. This allows for the assessment of product durability in salt spray environments, such as coastal areas.
  • Evaluation of protective coatings: This standard is particularly useful for assessing the quality and uniformity of coatings applied to metals to protect them from corrosion. The test allows for the detection of coating defects, such as pinholes and other imperfections, that can become a source of corrosion.
  • Simple and well-standardized method: The salt spray test is widely used due to its simplicity, speed, and precise standards that ensure repeatable results.

EN IEC 60068-2-52 Standard

EN 60068-2-52 is a European standard that specifies procedures for conducting a cyclic salt spray test. It applies to components and devices designed to operate in salt-containing atmospheres, such as marine environments. Salt can degrade the performance of parts made of metallic and non-metallic materials.

Purpose and Characteristics of the Standard. The primary purpose of the test is to assess resistance to salt-induced corrosion.

Unlike the simple salt spray test (EN 60068-2-11), this standard introduces cyclic conditions that more closely mimic the natural environment. The cyclic test consists of repeated phases, including salt spray, wet and dry storage, and standard atmosphere.

Test Procedures

The EN 60068-2-52 standard defines six different severity levels (test methods), each with unique requirements for the duration of each phase.

  • Levels 1 and 2 are intended for products used in or near marine environments.
  • Levels 3 to 6 are used for products that frequently transition between salty and dry atmospheres, such as cars and their components.

For example, a severity level 1 test requires four two-hour spray periods and a seven-day wet storage period. Severity level 6, on the other hand, involves eight test cycles, each consisting of four two-hour spray periods and a 20 to 22-hour wet storage period.

Mechanism of Action

The mechanism of corrosion on metallic materials in chloride-containing atmospheres is electrochemical, while the degradation of non-metallic materials is caused by complex chemical reactions between salt and the material. The standard allows for the assessment of both of these processes.

Climatic Chamber Testing

JSH Poland laboratory in Siemianowice Śląskie is equipped with a range of climatic chambers, from volumes of 0.125 m³ to larger ones of 1–1.5 m³, as well as large testing chambers enabling the examination of sizeable products and samples.
Tests are carried out using both accredited and non-accredited methods, in accordance with the requirements of the client and their customer.
We conduct tests according to the EN 60068-2 collection of methods, as well as corporate and product-specific standards tailored to the intended application of the product:

  • Environmental Testing – EN 60068-2-1: Test A: Cold
    The cold test is used for both heat-generating and non-heat-generating products. It is performed, among others, to test devices expected to operate throughout the entire duration of the exposure. The cold test is designed to determine the suitability of components, devices, or other products for use, transport, or storage under low temperature conditions.
  • Environmental Testing – EN 60068-2-2: Test B: Dry Heat
    The constant dry heat test is applied to both heat-generating and non-heat-generating products. It assesses the ability of components, devices, and other products to function, be transported, and stored at high temperatures. There are several subtypes: dry heat for non-heat-generating items (with gradual temperature change – Test Bb), dry heat for heat-generating items (Test Bd), and dry heat for powered heat-generating items (Test Be).
  • Environmental Testing – EN 60068-2-78: Test Cab: Constant Damp Heat
    This test determines the adaptability of products, components, or electrical devices to transport, storage, and use in high humidity conditions. The goal is to assess the effects of prolonged humidity at a constant temperature without condensation. It is suitable for both small and large devices, whether or not they generate heat.
  • Environmental Testing – EN 60068-2-14: Test N: Change of Temperature
    This test measures the impact of temperature variations—either a single change or a series—on products and samples. It evaluates the effect of low and high temperatures as well as humidity changes over time and frequency. Factors such as the time between temperature transitions and the number of temperature cycles can significantly affect the performance of products. It is especially used for automotive components, highly reliable electronic devices, and material samples to demonstrate resistance to thermal and humidity changes.
  • Environmental Testing – EN 60068-2-30: Test Db: Cyclic Damp Heat (12 h + 12 h cycle)
    This test assesses the ability of components, devices, or other products to function, be stored, or transported in high humidity conditions combined with cyclic temperature changes, which lead to condensation on the surface. Commonly used in automotive, railway, energy, and electronics industries, as well as for aging tests on materials like plastics, rubber, and others.
  • Environmental Testing – EN 60068-2-38: Test Z/AD: Composite Temperature/Humidity Cyclic Test
    This is a complex test procedure mainly intended for components, aiming to determine accelerated resistance to harmful effects of high temperature, humidity, and cold. The standard is not applicable to samples that are powered throughout the entire test. Samples may be powered during the constant phases of the test unless specified otherwise.
  • Environmental Testing – EN 60068-2-67: Test Cy: Constant Damp Heat, Accelerated Test Mainly for Components
    This accelerated test is used to evaluate the resistance of small electrotechnical products—particularly non-hermetically sealed components—to the damaging effects of damp heat. The test is not intended to assess external effects such as corrosion or deformation.

ATEX certification

Notified Body (NB 2057) J.S. Hamilton Poland – Certification Body, based in Siemianowice Śląskie, as a third party has the capability to carry out mandatory and voluntary conformity assessment of products based on the requirements of Directive 2014/34/EU of the European Parliament and of the Council of 26 February 2014 on the harmonisation of the laws of the Member States relating to equipment and protective systems intended for use in potentially explosive atmospheres.

Products intended for use in potentially explosive atmospheres must comply with the essential health and safety requirements of European Union Directive 2014/34/EU commonly referred to as the ATEX Directive. In order to determine whether a product meets the requirements of the directive, appropriate conformity assessment procedures must be applied.

According to the ATEX Directive, the level of protection and the associated assessment procedures depend directly on the level of hazard and the environment in which the equipment will operate.

The Certification Body for product groups I and II of category M1 and 1, respectively:

  • electrical appliances,
  • non-electrical equipment,
  • parts and components,
  • safety, control and regulation apparatus,
  • protection systems

for Group I and II products, categories M2 and 2:

  • internal combustion engines,
  • electrical equipment,
  • cparts and components,
  • protection, control and regulation apparatus,
  • medium and low voltage motors.

carries out the following conformity assessment procedures according to modules:

  • Module B: EU type examination (Annex III),
  • Module D: Conformity to type based on quality assurance of the production process (Annex IV),
  • Module F: Conformity to type based on product verification (Annex V),,
  • Module C1: Conformity to type based on internal production control and supervised product testing (Annex VI),
  • Module E: Conformity to type based on product quality assurance (Annex VII)
  • Module A: Internal production control (Annex VIII) + Transfer of technical documentation
  • Module G: Conformity based on unit verification (Annex IX)

 

The necessary tests required to confirm the explosion-proof performance of group I and II equipment of categories M1 and 1 and M2, 2 and 3 respectively are carried out in our own accredited testing laboratory No. AB 1552.

In addition to the obligatory EU Type Examination assessment, we carry out the non-obligatory Type Examination certification process for non-electrical equipment of categories M2 and 2 and equipment of category 3. This is an excellent way of confirming the conformity of products if you want the construction as well as the documentation to be verified by specialists. The process is similar to the EU Type Examination assessment, but applies to products for which no mandatory certification is required. The Type Examination Certificate does not, however, release you from additional procedures specific to the category and type of product, e.g. retention of documentation.

Module A: Internal production control (Annex VIII) + handing over of technical documentation applies mainly to the manufacturer, it is his responsibility to carry out the process of design, production, product quality supervision in accordance with the requirements of the essential safety requirements of the ATEX Directive. As an additional activity to which the manufacturer must pay attention is the retention of the documentation in the Notified Body. Documentation should be retained for 10 years after the end of production. The Notified Body of J.S. Hamilton accepts documentation in both paper and electronic form.

Food comes into contact with many materials and articles during production, processing, storage, preparation and serving, before its eventual consumption. Such materials and articles are called Food Contact Materials (FCMs). Food contact materials are either intended to be brought into contact with food, are already in contact with food, or can reasonably be brought into contact with food or transfer their constituents to the food under normal or foreseeable use. This includes direct or indirect contact.

Food contact materials (FCMs) are widely used in everyday life in the form of food packaging, dishes and utensils, tableware, food containers, etc. When put into contact with food, the different materials may behave differently and transfer their components to the food. If transferred in large quantities, many chemicals might endanger human health, or change the food itself. Therefore, food contact materials are subject to legally binding rules at EU level, currently laid down in Regulation (EC)1935/2004, which aims at ensuring FCM safety but also the effective functioning of the internal market in FCMs raw materials and final products. The purpose of this framework legislation for FCMs is to ensure the effective functioning of the internal market for materials and articles intended to come into contact with food and secure a high level of protection of human health, as well as the interests of consumers.

(EC)1935/2004 provides general requirements that all FCMs must be manufactured in accordance with good manufacturing practice (GMP) so that they are safe and do not change the properties of food in unacceptable ways. As the general requirements for all FCMs set out under Article 3 are linked to the general obligations on GMP, separate rules on GMP are laid down in Commission Regulation (EC)2023/2006. It also specifies other rules, including those on labelling and on compliance documentation and traceability, and lays down the risk assessment process involving EFSA as part of the authorization process for substances.

 

The following are examples of key legislation currently binding in Europe:

EU FCMs requirements overview
 

General Regulations on FCM
Regulation EC 1935/2004 (on materials and articles intended to come into contact with food)
Regulation EC 2023/2006 (on Good Manufacturing Practices)
 

Specific Materials
Ceramics Directive 84/500/EEC
Epoxy Resins Regulation (EC) 1895/2005
Regenerated Cellulose Film Directive 2007/42/EC
Recycled Plastics Materials Regulation (EC) 282/2008
Active and Intelligent Packaging Regulation (EC) 450/2009
Plastics Regulation (EU) 10/2011
 

Specific Regulations
Regulation (EU) 321/2011 (restricting the use of bisphenol A in polycarbonate infant feeding bottles)
Regulation (EU) 284/2011 (import procedures for polyamide and melamine plastic kitchenware from China and Hong Kong)
Regulation (EC) 1895/2005 (restricting the use of certain epoxy resins)
Directive 93/11/EEC (regulating the release of N-nitrosamines and N-nitrosatable substances from rubber teats and soothers)

 

The declaration of compliance (DoC) is a document that contains basic information about FCMs as required by applicable laws. The DoC should contain information about the following:

  • who manufactured or imported the materials or articles or the raw materials intended for their manufacture,
  • what they are,
  • date of the declaration,
  • confirmation that the materials or articles meet relevant requirements laid down in Regulation (EC) No 1935/2004 on materials and articles intended to come into contact with food and in any specific measures,
  • information about the compliance of substances used that are subject to any restrictions and/or specifications that will allow the downstream businesses ensure compliance with those restrictions,
  • information about the compliance of substances subject to a restriction in food, about the level of their specific migration and, where appropriate, purity criteria to enable the user of these materials or articles to comply with the law,
  • specifications on the use of the material or article, such as:
  • type or types of food it is intended to be put in contact with,
  • time and temperature of treatment and storage in contact with the food,
  • ratio of food-contact surface area to volume used to establish the compliance of the material or article,
  • confirmation that the material or article complies with any rules on functional barriers when one is incorporated into the material or article.

 

Microbiological testing

The safety of food is a priority not only to consumers and manufacturers, but also to legislative bodies. That is why laws determine the necessary safety criteria that all food products need to comply with. In this article, we discuss those related to the microbiological parameters of food.

Regulation (EC) No 178/2002 of the European Parliament and of the Council of 28 January 2002 laying down the general principles and requirements of food law, establishing the European Food Safety Authority and laying down procedures in matters of food safety, as amended, which is the basic piece of EU legislation formulating the principles and requirements of European food law, prohibits the placing on the market of food that is not safe. Food business operators are obliged to withdraw unsafe food from the market.

Commission Regulation (EC) No 2073/2005 of 15 November 2005 on microbiological criteria for foodstuffs, as amended, lays down harmonised safety criteria for the evaluation of food products as regards pathogenic micro-organisms to increase the protection of public health and to avoid divergent interpretations. This regulation and subsequent amending regulations establish harmonised food safety criteria for certain pathogenic micro-organisms. These criteria also serve to validate and verify HACCP procedures and other hygiene control measures.

In the light of the legal acts cited, a distinction is made between:

    1. food safety criteria, i.e. requirements determining the acceptability of a product or a batch of foodstuff, applied to products placed on the market. This group includes:
      • Salmonella (including serogroups Typhimurium and Enteritidis),
      • Listeria monocytogenes,
      • Cronobacter,
      • Escherichia coli,
      • Shiga-toxin producing E. coli (STEC) O157, O26, O111, O103, O145 and O104:H4,
      • Staphylococcal enterotoxins,
    2. process hygiene criteria, i.e. requirements for the acceptance of a functioning production process. They do not apply to products placed on the market. These criteria determine the indicative value of contaminants, exceeding which corrective actions are necessary to maintain the hygiene of the process at the level compliant with the food law. This group includes:
      • Aerobic bacteria count,
      • Enterobacteriacae,
      • Salmonella,
      • Escherichia coli,
      • Campylobacter spp.,
      • Coagulase-positive staphylococci,
      • Bacillus cereus.

The microbiological laboratories of J.S. Hamilton Poland offer comprehensive hazard monitoring at every stage of production, including environmental control, using the methodology specified in Polish standards, harmonised with European and ISO standards.

In addition to the tests included in the above criteria, we also perform the following microbiological analyses:

  • Bacillus subtilis,
  • Bacillus coagulans,
  • Listeria spp.,
  • Cronobacter spp.,
  • Alicyclobacillus spp.,
  • Moulds and yeasts,
  • Lactic acid bacteria,
  • Acetic acid bacteria,
  • Aerobic psychrotrophic microorganisms,
  • Spore-forming and non-spore-forming anaerobes, meso- and thermophilic,
  • Clostridium perfringens,
  • Clostridium botulinum,
  • Enterococcus,
  • Pseudomonas,
  • Characteristic bacteria in yoghurt,
  • Osmophilic moulds and yeasts,
  • Durability testing by thermostat test.

In addition to classical, standardised methods, J.S. Hamilton Poland laboratories have validated and accredited rapid alternative methods, based on the BAX® automated system based on the detection of a specific DNA sequence characteristic for pathogenic microorganisms. These methods are applicable to testing food, environmental samples from food production and trade areas. Using the BAX® system, we can determine the presence of such pathogens as:

  • Salmonella,
  • Listeria monocytogenes,
  • Escherichia coli O157:H7,

and for meat and meat products, vegetables, fruit and sprouts:

  • Shiga-toxin producing Escherichia coli (STEC) O157, O26, O111, O103, O145 oraz O104:H4.

As part of its services, J.S. Hamilton Poland also offers fast and precise detection of viruses present in ready-to-eat foods, which are not subjected to heat treatment during preparation and do not require heat treatment before consumption. These viruses mainly include:

  • Hepatitis A virus,
  • Noroviruses (also known as Norwalk viruses).

Using RT-PCR (reverse transcription PCR) we can determine their presence in matrices such as:

  • Fruit and processed fruit,
  • Vegetables and processed vegetables,
  • Environmental samples from the food production and marketing area.

Within the scope of accreditation, we also carry out microbiological analyses of drinking water, as well as tests of microbiological purity of packaging intended for contact with food.
