The VW PV 3929 test standard is a standard for testing the aging behavior of plastics (such as color or gloss change) that are likely to be exposed to air and sunlight. Samples undergo an accelerated attrition program in a dry and hot climate and are irradiated using xenon arc light.
VW regulation PV 3929 describes a laboratory test of the aging behavior of plastics and elastomers exposed to weathering and sunlight according to artificial weathering (xenon arc light). Test conditions simulate a specific dry-hot climate (eg Kalahari, South Africa and Arizona). According to PV 3929, the test is primarily used for the first sample release.
In some applications, changes in mechanical properties or cracking may be aging criteria. Therefore, additional tests such as tensile tests, determination of impact strength, determination of hardness and microscopic examinations may be necessary.
Filters should be used to adapt xenon arc light to spherical irradiation with spectral distribution of ultraviolet and visible radiation. Each of the test conditions defines a year cycle in climatic regions such as Arizona and South Africa, with close reference to the average UV radiation dose in dry heat in nm.
Our EUROLAB test laboratory complies with ISO/IEC 17020 General requirements for the competence of testing and calibration laboratories to help ensure accuracy and precision in performing tests, obtaining data and reporting results. EUROLAB comes with plastic testing, detailed test reports, images of labels before and after testing, and all test data so it can be examined and analyzed.
