The test laboratory in Siemianowice Śląskie carries out tests in the following areas
measurements of direct and alternating voltages
- alternating and direct current measurements
- frequency and capacitance measurements
- inductance measurements
- resistance measurements and diode tests
- leakage resistance to earth (floors, work surfaces, shelves, trolleys, chairs)
- resistance of the “man/shoe/floor” system (effectiveness of earthing through ESD shoes and the floor in question)
- point-to-point resistance (floors, work surfaces, flat materials, clothing), electrification,
- electrical insulation strength
- insulation resistance of cable lines, transformers, motors and other electrical equipment, also equipment used in telecommunications,
- insulation clearances
- capacity of cells and batteries,
- short-circuit resistance of cells and batteries,
- protection against residual voltage
- continuity of protective circuitry and resistance of protective and equalising circuits,
- surface resistance RS, RV cross resistance, resistance between RP points of non-metallic materials,
- resistance of pipes and hydraulic hose made of plastic and rubber,
- thermal – heating, temperature rise, maximum temperature
- using contact and non-contact methods (thermal imaging),
- intrinsically safe systems.
