1.1 本规范涵盖结构粘土承重面砖。结构面砖是设计用于建筑物内、外墙和隔墙的瓷砖。 1.2 本规范的性能要求在购买时适用。使用从砌体结构中提取的瓷砖测试结果来确定是否符合性能要求（第 6. )本标准不在本规范范围内。 1.3 本规范涵盖的瓷砖由粘土、页岩或类似天然物质制成，并在高温下进行热处理（燃烧）。 热处理必须在颗粒成分之间形成足够的燃烧结合，以满足本规范的强度和耐久性要求。（参见 点火 和 烧制债券 在术语方面 C1232 .) 1.4 本规范的正文引用了提供解释材料的注释和脚注。这些注释和脚注（不包括表和图中的注释和脚注）不应视为本规范的要求。 1.5 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。 1.6 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。

1.1 This specification covers structural clay loadbearing facing tile. Structural facing tile are tile designed for use in interior and exterior unplastered walls and partitions of buildings. 1.2 The property requirements of this specification apply at the time of purchase. The use of results from testing of tile extracted from masonry structures for determining conformance or nonconformance to the property requirements (Section 6 ) of this standard is beyond the scope of this specification. 1.3 Tile covered by this specification are manufactured from clay, shale, or similar naturally occurring substances and subjected to a heat treatment at elevated temperatures (firing). The heat treatment must develop sufficient fired bond between the particulate constituents to provide the strength and durability requirements of this specification. (See firing and fired bond in Terminology C1232 .) 1.4 The text of this specification references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification. 1.5 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. 1.6 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.
