1.1 本试验方法包括测定表面面积至少为1的瓷砖、马赛克瓷砖、采石场瓷砖、瓷砖和铺路砖的断裂强度 在里面 2. (6.4 厘米 2. ). 瓷砖可以上釉或不上釉。 1.2 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 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 该试验方法提供了确定大量瓷砖是否满足瓷砖规范中可能出现的强度要求的方法。瓷砖强度是指从压力表中读取的导致瓷砖破裂所需的力，单位为磅力（或牛顿）。

1.1 This test method covers the determination of the breaking strength of ceramic tile, ceramic mosaic tile, quarry tile, porcelain tile and paver tile, having a facial area of at least 1 in. 2 (6.4 cm 2 ). Tiles may be glazed or unglazed. 1.2 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. 1.3 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 test method provides means for establishing whether or not a lot of ceramic tile meets the strength requirements which may appear in tile specifications. Tile strength is the force in pounds-force (or newtons), as read from the pressure gage, necessary to cause the tile to break.
