Standard Test Method for Adherence of Porcelain Enamel Coatings to Sheet Metal
1.1 The scope of this test method is:
1.1.1 To determine quantitatively the amount of enamel remaining after the porcelain enamel coating specimen has been deformed;
1.1.2 To standardize the deformation parameters for testing adherence of porcelain enamel to sheet metal; and,
1.1.3 To provide a quantitative adherence rating scale for comparison to reference standards.
1.2 This adherence test method is applicable to porcelain enamel coatings on substrates from 18 to 24 gage (0.0478 to 0.025 in. or from 1.214 to 0.654 mm).
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 and health practices and determine the applicability of regulatory limitations prior to use.
