1.1 This SAE Standard specifies the operating procedures for a controlled irradiance, xenon-arc apparatus used for the accelerated exposure of various exterior automotive materials. 1.2 This is a performance standard based on the test parameters of SAE J1960. 1.3 The sample preparation, test durations, and performance evaluation procedures are covered in material specifications of the different automotive manufacturers. 1.4 Equipment qualified to perform this test is determined by material test comparison between instruments approved for SAE J1960 and those intending to perform SAE J2527. 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, this committee is developing a `Protocol To Verify New Test Apparatus' identified as SAE J2413.
