This test method specifies the operating procedures for a controlled irradiance, xenon arc apparatus used for the accelerated exposure of various automotive interior trim components. This is a performance standard based on the test parameters of SAE J1885. Test duration as well as any exceptions to the sample preparation and performance evaluation procedures contained in this document, are covered in material specifications of the different automotive manufacturers. Equipment qualified to perform this test is determined by material test comparison between instruments approved for SAE J1885 and those intending to perform SAE J2412. A specific test protocol to compare new test equipment to those previously approved must be done by material test comparison by the contractual parties. The interested contractual companies shall identify details of the test protocol and the materials to be tested. At the time of publication of this test method, the committee is developing a 'Protocol To Verify New Test Apparatus' identified as SAE J2413. Any deviations to this test method, such as filter combinations, is to be agreed upon by contractual parties.
