1.1 本试验方法包括测定搪瓷用钢板在给定的一组最坏情况下是否会重新沸腾。 1.2 以英寸-磅为单位的数值应视为标准值。括号中给出的值仅供参考。 1.3 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。 1.4 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====== 5.1 该试验的结果表明，在一组给定的搪瓷条件下，钢板是否会导致重新沸腾，并使搪瓷处理器确定成品涂层中可能存在的缺陷源。 5.2 本试验方法通常用于测试钢板批次、线圈或升降机中的样品，这些钢板由于某种原因，生产问题、搪瓷零件上明显的缺陷或生产经验被怀疑会导致搪瓷器皿中出现重新沸腾的缺陷。它通常用于确定裸钢是否存在问题或其他因素，如搪瓷、加工污染等。

1.1 This test method covers the determination of whether a sheet steel for porcelain enameling will reboil under a given set of worse case conditions. 1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 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 ====== 5.1 The results of this test indicate whether or not a sheet steel will cause reboiling under one given set of enameling conditions and enable the enamel processor to establish a possible source of imperfections in the finished coating. 5.2 This test method is normally used to test samples from lots, coils, or lifts of sheet steel which for some reason, production problems, defects evident on enameled parts, or production experience are suspected of causing defects in enameled ware which have the appearance of reboiling. It is often used to establish whether a problem exists with the bare steel or other factors such as the porcelain enamel, processing contamination, and so forth.
