Product light and weather conditions resistance tests

Testing in solar simulation chamber – metal halide lamps

Determination of materials and components resistance for solar radiation is very important aspect of products’ quality evaluation. Simulation of external conditions effect on materials may be performed with various methods. In case of solar radiation simulation the kind of light source is of great importance due to differences in spectral characteristics. Radiation emitted by metal halide lamp very closely simulate spectral energy distribution and intensity of solar radiation – in reference with CIE publication No. 85 (spectral range: UV-VIS-IR i.e. 280 ÷ 3000 nm) with fully regulated intensity.
 
Testing of components and assemblies in solar simulation chambers allows determination of changes in such properties as shape, color, gloss or strength. Other characteristics that are common evaluated are presence of stains, cracks or delamination and other aesthetic and functional aspects.
 
Chamber allows performing of::
  • cyclic tests,
  • long-term tests,
Introduction of appropriate filters allows simulation of:
  • outdoor conditions (simulation of outdoor climatic conditions effect on vehicle’s exposed surfaces),
  • indoor conditions (simulation of climatic conditions inside the close passenger compartment).

Resistance to weather conditions. Exposure to laboratory light sources. Xenon-arc lamps

The test method consists of exposing working samples to artificial weather conditions (filtered xenon lamp, temperature, humidity and precipitation) in order to simulate ageing processes that occur as a result of natural weather conditions, in the laboratory. Resistance to weather conditions is assessed by comparing the colour change of the tested working sample to a sample not exposed by means of a gray scale according to ISO 105-A02.

Resistance to light. Exposure to laboratory light sources. Xenon-arc lamps.

The test method consists of determining the colour fastness and ageing characteristics of the products in response to artificial light simulating natural daylight passing through window glass with the unmistakable action of heat. The working sample of the tested product is subjected to artificial light under defined conditions. Colour fastness is assessed by comparing the colour change of the test specimen to a non-exposed specimen, in accordance with ISO 105-A02.
