5、 arc test apparatus ability to perform SAE J1885, J1960, J2412, J2527, or other as specified. 1.2 This Protocol defines the process for analysis of performance capabilities of candidate xenon arc test apparatus for comparison to current xenon arc test apparatus being utilized by the industry. This w

6、ill require documentation of the candidate apparatus to: a. Produce the exposure environments as specified in the test method. b. Produce the required degradation in the standard reference material(s) in the specified time frame. c. Produce satisfactory repeatable and reproducible exposure results.

7、d. Produce satisfactory uniform results throughout the specimen exposure region of the test chamber. e. Produce similar degradation in the benchmark test specimens, as agreed upon by contractual parties. Standard Reference Materials (SRMs) performance data and any specified benchmark materials are u

8、sed as a basis for comparison of various test apparatus. The type of failure and mode of failure should be the same for the comparison. 2.

Repeatability and Reproducibility 6.1 The manufacturer shall submit data showing that the test apparatus is capable

19、 of producing repeatable and reproducible exposure results. 6.1.1 Repeatability shall be documented by repeating the exposure of the standard reference material in three separate exposure runs in the same piece of test apparatus. 6.1.2 Reproducibility shall be documented by repeating the exposure of

20、 the standard reference material in three separate exposure runs - one each, in three different test apparatus (same model but different serial numbers). 7. Exposure Uniformity 7.1 The test apparatus manufacturer shall submit data documenting the variability within the testing area. The data will in

21、clude mapping the testing area with the current lot of SRM or other material agreed upon by contractual parties. 7.2 Uniformity shall be demonstrated by exposing replicate specimens of a standard reference material at various locations within the specimen mounting region of the chamber.
