Micom Laboratories is pleased to announce that it now offers SAE J2020 testing as part of its automotive testing services. This method describes an accelerated weathering test which allows to assess the performance of exteriors automobiles segments by the means of UV testing . Indeed, it is through the use UVA or UVB lamps that it is possible to simulate an outdoor environment that is encountered on the surface of a car and thus allows to foresee the performance of the sample in the field. Hence, this method is based on the ASTM G154 standard.
SAE J2020 tests
The goal of SAE J2020 is to predict the performance over time of exterior automotive materials by the means of an accelerated weathering test. More specifically, this method gives the test conditions that are required to simulate the environmental conditions that are encountered on the outside of a car. Indeed, it is through the use of UVA or UVB lamps and on a two-stage cycle, which consists of a UV and of a condensation period that it is possible to appraise the effects of heat and sunlight on the samples. From the gathered data, it is possible to foresee the evolution of the performance of the automotive material under normal conditions. Lastly, as mentioned in our UV testing eBook , accelerated fluorescent UV exposure is primarily employed to assess the loss of mechanical properties and yellowing i.e., no color fading. If the aesthetics are the main point of concern, it is recommended to use a method that is based on the ASTM G155 standard.
Micom offers polymer testing services for a wide selection of material and products. For more information about the SAE J2020 test, we invite you to contact our material testing laboratory today. It will be our pleasure to answer your questions about either of those tests.
