Xenon test

Year after year production damages into the millions are caused by heat, sunlight and humidity. Yellowing, bleaching, blurring or crack formation can cause damages outdoors as well as indoors. With our xenon test chamber we can simulate damages caused by high temperatures, full spectrum sunlight and humidity. The test chamber reproduces the whole spectrum of sunlight (ultraviolet light, visible light and infrared light). Deployed are daylight filters (Daylight Q, B/B, Q/B), indoor filters (window filter Q, B/SL), extended UV-filters (more UV-share) and other filters (window IR).

Light fastness plastics

Accelerated light fastness tests for plastics and packaging materials can reveal many possible defects that can lead to material degradation of their products. The absorption of harmful radiation leads to chemical processes that change the color. Other possible errors are yellowing of polymers, bubble formation or color changes.

Standards: DIN EN ISO 4892-2, SAE J2412

Light fastness test automotive

Automotive interiors in passenger cars but also in trucks and buses are exposed to extreme sunlight conditions. We offer light fastness tests in accordance with automotive standards so that you can determine the possible weak points of your products in advance.
Standards: SAE J2412, PV 3929, PV3930

Light fastness testing of textiles

UV radiation and solar radiation in general is a major problem regarding textiles wear. Textiles generally fade under direct or indirect light. The extent to which this bleaching occurs over a certain period of time depends on the quality of the textiles.

The light fastness of textiles can be measured. A frequent test method is DIN EN ISO 105-B02.
Standards: DIN EN ISO 105-B02, DIN EN ISO 105-B04, DIN EN ISO 105-B06, DIN EN ISO 105-B07

Weathering test on laminated safety glass

Laminated safety glass applications for architecture, photovoltaics or automobiles can be subject to material ageing due to solar radiation and climatic stress. You can have your products tested in our laboratory with a weathering test, e.g. according to ASTM D2565 (for outdoor applications). Subsequently, a classical material test (bending or tensile test) can be used to determine whether there is a loss of the mechanical properties of the material.

Standards: ASTM D2665

Weathering test plastics

Plastics generally age under direct or indirect exposure to light, mostly due to UV radiation. If the exposure to light is accompanied by exposure to moisture, it is not only decisive how strongly the plastics age, but also how the material properties change over a certain period of time. The loss of mechanical properties can be measured. A frequent test method is an accelerated outdoor test according to DIN EN ISO 4892-2. This takes into account solar radiation and alternating dry and wet cycles.

Standards: DIN EN ISO 4892-2, DIN EN ISO 105-B04, DIN EN ISO 105-B06, ASTM D2565, ASTM D7356 / D7356M – 19
