Plastics
Plastics consist mainly of macromolecules and are divided into three groups: elastomers, duroplasts and thermoplastics. The tests such as formability, hardness, elasticity, breaking strength, temperature, heat resistance and chemical resistance are performed on plastics.
The amount of glass fiber content and filler plays an important role in Kunsttsoffen. The determination of the glass fiber content is made by ashing.
Artificial irradiation or weathering in equipment
Xenon-arc lamps DIN EN ISO 4892-2
A filtered xenon arc lamp is used to simulate the relative spectral irradiance of global radiation in the ultraviolet (UV) and visible wavelengths of the spectrum.
The test specimens are exposed under controlled environmental conditions to different levels of radiation, heat, relative humidity and water (see 3.).
