Standard Test Method for Evaluating Degree of Resistance to Wear of Traffic Paint
SCOPE
1.1 This test method covers the evaluation of degree of resistance to wear that may occur with traffic paints in road tests (see Practice D 713) or in actual service, using photographic standards for comparative evaluation.
1.2 This standard does not purport to address all of the safety problems, 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.
