1. Scope

1.1 This practice covers the selection of test conditions for accelerated exposure testing of coatings and related products in xenon arc devices conducted according to Practices G 151 and G 155. This practice also covers the preparation of test specimens, the test conditions suited for coatings, and the evaluation of test results. Table 1 describes commonly used test conditions.

Note 1ISO 11341:1994 also describes xenon-arc exposures of paints and coatings. However, the exposure conditions described in ISO 11341 are different than those listed in Table 1.

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
