1.1 本试验方法的范围为: 1.1.1 定量测定搪瓷涂层试样变形后残留的搪瓷量； 1.1.2 标准化测试瓷釉与金属板粘附性的变形参数；和 1.1.3 提供定量依从性评分量表，用于与参考标准进行比较。 1.2 该粘附性试验方法适用于18至24 gauge（0.0478至0.025 in.或1.214至0.654 mm）基底上的搪瓷涂层。 1.3 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。 本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 2.1 测量搪瓷系统（如地涂层、地涂层/覆盖层和直接覆盖层搪瓷）中的粘附性，是监测金属制备、搪瓷应用厚度、钢材选择和搪瓷选择中的工艺变量以及确保成品最终质量的重要程序。

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 gauge (0.0478 to 0.025 in. or from 1.214 to 0.654 mm). 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 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. 1.5 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. ====== Significance And Use ====== 2.1 The measurement of adherence in porcelain enamel systems, such as ground coat, ground coat/cover coat, and direct-on cover-coat enamels, is an important procedure for monitoring process variables in metal preparation, enamel application thickness, steel selection, and enamel selection, as well as assuring the ultimate quality of the finished product.
