VW PV 3930 Weathering Test Standard for Non-Metallic Materials in Humid-Hot Climate


The VW PV 3930 standard describes the procedure for testing the aging behavior (e.g. change in color and gloss) of plastics, elastomers and folding top cloths, as well as paint and similar coatings exposed to air and sunlight.

The test is carried out by artificial aging in a humid and warm climate (eg Florida). It is used for testing, sample and standard production monitoring.

For certain applications, aging criteria may consist of changes in mechanical properties or cracking. Therefore, additional tests may be required in addition to visual evaluation and measurement of color and gloss. These tests may include, for example, tensile tests, determination of impact resistance, determination of hardness, and microscopic examinations.

The main factors to consider when performing this test are: filter type, rain cycle, temperature of the black standard and sample room during the dry period, relative humidity, intensity of irradiation, exposure time and irradiation dose.

The PV 3930 is a test method detailing the test conditions required to perform an accelerated aging that simulates a humid and hot climate. Conversely, the PV 3929 is also a Volkswagen-specific test method that simulates a dry and hot climate. Also, the conditions listed in the PV 3930 standard represent one year of UV radiation consisting of wavelengths of 300 and 385 nm. The main purpose of this method is to evaluate aesthetics and in some cases some mechanical properties need to be evaluated.

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.
