| Résumé : |
SAE J2527 (Performance Based Standard for Accelerated Exposure of Automotive Exterior Materials Using a Controlled Irradiance Xenon-Arc Apparatus) has been the industry standard for testing automotive exterior coatings since its inception in 2004. Since then, the standard has gone unchanged despite many of the advances in weathering testing over the past decade.
In order to better predict how high-performance materials will perform outdoors, a revision of this standard is imperative. Technological advances in the performance of weathering testers, control of conditions and general understanding of the mechanisms of weathering can be applied to make SAE J2527 a better test method. These changes do not make the standard more restrictive and anyone with a Xenon-Arc chamber capable of meeting this test method, such as the Q-SUN Xe-3-HBS from Q-Lab Corporation, will still be able to run this test.
A recent ballot has revised this standard, implementing some changes to reflect these new advances. |
