AGING TESTS – LIGHT AND UV RESISTANCE

Producers and users of products often wonder how long my product will retain its physical, mechanical, strength properties or whether it will retain its external appearance, color and luster during its use and operation.

Xenon and UV aging tests, which we perform at the J.S. Hamilton Poland laboratory, will help determine the characteristics of your products. They are subjected to daylight, moisture and rain and can degrade. Specialists have the knowledge and technical capabilities to verify the effects of the above factors on the surfaces of samples. We carry out accelerated aging tests that simulate the natural atmospheric conditions under which the tested item is used.

We are able to determine how much your products will retain their physical and mechanical properties and appearance. We use methods that check the resistance to conditions in different latitudes of the world, and we subject samples to aging tests that simulate processes occurring after 2,3 or more years.

In our laboratory, we carry out tests according to the following standards:

  • PN-EN IEC 60068-2-5:2018 – Environmental tests – Part 2-5: Tests – S test: Mapping of solar radiation occurring on the earth’s surface and guidelines for testing the effects of solar radiation and weather conditions,
  • PN-EN ISO 4892-1:2016-06 – Plastics – Methods of exposure to laboratory light sources – Part 1: General principles,
  • PN-EN ISO 4892-2:2013-06 – Plastics – Methods of exposure to laboratory light sources – Part 2: Xenon arc lamps,
  • PN-EN ISO 16474-1:2014-02 – Paints and varnishes – Methods of exposure to laboratory light sources – Part 1: General remarks,
  • PN-EN ISO 16474-2:2014-02 – Paints and varnishes – Methods of exposure to laboratory light sources – Part 2: Xenon arc lamps.
  • PN-EN ISO 4892-3 Plastics – Methods of exposure to laboratory light sources – Part 3: UV fluorescent lamps.

Depending on the research program, appropriate min. parameters are selected :

  • number and length of cycles
  • light filter
  • irradiation level
  • length of light and dark periods
  • sample moistening (spraying)
  • temperature during exposure to light as in the darkness
  • relative humidity in the chamber during exposure to light as in darkness

The test should be conducted until the intended exposure time or radiation dose is achieved. After the test, the samples are subjected to visual and dimensional inspection, strength tests and functional tests.
