ASTM D2485-91(2007)

Some coating systems are developed for use over steel that is exposed to high temperatures during service life. This method provides an accelerated means of determining the performance of these coating systems. Testing of coatings designed for interior service, and of coatings designed for exterior (weather-exposed) service is included.

1.1 These test methods cover the evaluation of the heat-resistant properties of coatings designed to protect steel surfaces exposed to elevated temperatures during their service life. Two test methods are described as follows:

Method A-Interior Service Coatings

Method B-Exterior Service Coatings

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

This standard does not purport to address the safety concerns, if any, associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 5.
