1. Scope

1.1 This practice covers the determination of the relative service of exterior paints and other materials of similar purpose when applied on steel surfaces exposed out-of-doors.

1.2 Experience indicates that the steel used as a test surface has a marked bearing upon the weathering results. It is the purpose of this test method to minimize the influence of variation in steel surfaces on any series of tests by providing for uniformity in the selection of the steel surface, particularly in cooperative work. This practice also outlines uniform procedures for conducting the exposure tests and for evaluating and recording results.

1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

1.4 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.
