(Test Method)Standard Test Method for Detergent Resistance of Ceramic Decorations on Glass Tableware
Standard Test Method for Detergent Resistance of Ceramic Decorations on Glass Tableware
SIGNIFICANCE AND USE
4.1 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 C927 when long term performance of enamels must be evaluated.
SCOPE
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, 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.
