ASTM D6944-03 - 10.7.2003
 
Significance and Use

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 used are applied and cured according to the given specifications of the coating manufacturer.

 
1. Scope

1.1 This test method determines the resistance of cured coatings to repeated thermal cycles. This procedure is designed to assess the influence of thermal cycling on adhesion and other properties of coatings. 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 and health practices and determine the applicability of regulatory limitations prior to use.
