Significance and Use
4.1 The purpose of this test is to obtain information on the ability of a coating system to adhere to substrates under thermal stress. It is assumed that the coating systems tested are applied and cured according to the coating manufacturer’s instructions.
1.1 This practice determines the resistance of cured coatings or coating systems to repeated thermal cycles and is designed to assess the effect of thermal cycling on the properties of a coating or coating system. These properties may include adhesion, resistance to checking, cracking, blistering, or others. This procedure is not intended to provide a quantitative measure of the service life that can be expected from a specific coating system on a given substrate.
1.2 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.
1.3 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.
