This test method provides a means of estimating the qualitative performance of glass enamel decorations that are exposed to high phosphate detergents during use. This test method also attempts to simulate accelerated exposure to high phosphate detergents prior to testing for heavy metal release, such as in Test Method C 927 when long term performance of enamels must be evaluated.

1.1 This qualitative test method is designed to provide a convenient and reproducible method of determining the detergent resistance of decorations applied to glass tableware.

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.
