Standard Practice for Solvent and Fuel Resistance of Traffic Paint

SIGNIFICANCE AND USE
4.1 Traffic paints must have good resistance to motor oil and fuel drippings on the highway. This test method describes the procedure necessary to evaluate the resistance of traffic paint to reference test fluids in order to simulate this type of action.
SCOPE
1.1 This practice describes a laboratory procedure for determining the resistance of a dried film of traffic paint to the action of a specified hydrocarbon solvent or gasoline fuel test fluid.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
