PV 3930 : Automotive accelerated weathering standards

Volkswagen – Non-metallic materials – moist, hot climate.

A standard for testing the ageing behaviour of plastics (such as a change in colour and/or gloss), which are likely to be subjected to weather and daylight. Samples undergo an accelerated weathering programme of a moist, hot climate and are irradiated using xenon arc light and are periodically moistened.

Filters shall be used to adapt the Xenon arc light to the global radiation with its spectral distribution of ultraviolet and visible radiation. The test conditions each describe a year cycle, with reference to conditions of moist, hot climate zones such as Florida.

NOTE: Additional tests may be required, along with a visual evaluation, if the ageing causes changes in the mechanical properties and/or cracking. Further tests may include tensile tests, determination of impact resistance, determination of hardness and microscopic examinations.
