Significance and Use | ||||||
3.1 This test method is used to indicate the deformation tendency of microcellular materials that may occur during paint application in an assembly plant operation. Since a standard specimen is used, do not assume heat sag measurements to be exactly those which will occur on a part during or after the paint application and baking operation of an assembly process. 3.2 Before proceeding with this test method, reference shall be made to the specification of the material being tested. Any test specimen preparation, conditioning, or dimensions, or combination thereof, and testing parameters covered in the materials specification shall take precedence over those mentioned in these test methods. If there are no material specifications, then the default conditions apply. Note 2: This test method is applicable to solid
urethanes.
