ASTM D868-85(1998)

Standard Test Method for Evaluating Degree of Bleeding of Traffic Paint

SCOPE
1.1 The photographic reference standards that are part of this test method  are representative of the degrees of bleeding of traffic or pavement marking paints. The standards are intended primarily for comparative evaluation in the laboratory.  
1.2 Bleeding as defined is the only type of discoloration in this test method.  
1.3 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.>
