1、Designation:D669508Standard Practice forXenon-Arc Exposures of Paint and Related Coatings1This standard is issued under the fixed designation D6695;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in
2、 parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice covers the selection of test conditions foraccelerated exposure testing of coatings and related products inxenon arc devices conducted
3、 according to Practices G151 andG155.This practice also covers the preparation of testspecimens,the test conditions suited for coatings,and theevaluation of test results.Table 1 describes commonly used testconditions.NOTE1ISO 11341 also describes xenon-arc exposures of paints andcoatings.However,the
4、 exposure conditions described in ISO 11341 aredifferent than those listed in Table 1.1.2 The values SI units are to be regarded as standard.Thevalues given in parentheses are for information only.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.
5、It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D358 Specification for Wood to Be Used as Panels inWeathering Tests of Coatings
