1. Scope
1.1 This test method describes laboratory accelerated weathering procedures using either fluorescent ultraviolet or xenon arc test devices for determining the color stability of building construction sealants.
1.2 Color stability rankings provided by these two procedures may not agree.
1.3 The values stated in SI units are to be regarded as the standard. Values given in parentheses are for information only.
1.4 There is no equivalent ISO standard for this test method.
1.5 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.
