1.1 本规范涵盖了不要求外观的结构和非结构砌体中使用的砖。砖是棱柱形单元，有各种尺寸、形状、纹理和颜色。本规范不包括拟用作饰面单元或要求表面外观的砖。如果要求砖具有特定的颜色、纹理、光洁度、均匀性，或限制裂缝、翘曲或其他有损外观的缺陷，则应根据规范购买 第216页 .本规范不包括拟用作铺路砖的砖（见规范 C902 和 1972年 )。 1.2 本规范的要求在购买时适用。使用从砌体结构中提取的砖的测试结果来确定是否符合本规范的要求超出了本标准的范围。 1.3 砖是主要由粘土、页岩或类似的天然泥土物质制成的陶瓷产品，并在高温下进行热处理（烧制）。允许包括添加剂或回收材料，由制造商选择。热处理必须在颗粒成分之间形成足够的烧结结合，以提供本规范的强度和耐久性要求（见术语 232英镑 )。 1.4 砖在制造过程中通过成型、压制或挤压成型，成型方法是描述砖的一种方式。 1.4.1 本规范及其单独要求不得用于鉴定或证实由其他材料制成、或采用其他成型方法或其他材料粘合方式制成的砌体单元的性能。 1.5 覆盖了三个等级的砖。 1.6 本规范的文本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）不应被视为规范的要求。 1.7 以英寸磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 1.8 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This specification covers brick intended for use in both structural and nonstructural masonry where external appearance is not a requirement. The brick are prismatic units available in a variety of sizes, shapes, textures, and colors. This specification does not cover brick intended for use as facing units or where surface appearance is a requirement. If brick are required to have a particular color, texture, finish, uniformity, or limits on cracks, warpage, or other imperfections detracting from the appearance they are purchased under Specification C216 . This specification does not cover brick intended for use as paving brick (see Specifications C902 and C1272 ). 1.2 The requirements of this specification apply at the time of purchase. The use of results from testing of brick extracted from masonry structures for determining conformance or nonconformance to the requirements of this specification is beyond the scope of this standard. 1.3 Brick are ceramic products manufactured primarily from clay, shale, or similar naturally occurring earthy substances and subjected to a heat treatment at elevated temperatures (firing). Additives or recycled materials are permitted to be included at the option of the manufacturer. The heat treatment must develop sufficient fired bond between the particulate constituents to provide the strength and durability requirements of this specification (see Terminology C1232 ). 1.4 Brick are shaped during manufacture by molding, pressing, or extrusion, and the shaping method is a way to describe the brick. 1.4.1 This specification and its individual requirements shall not be used to qualify or corroborate the performance of a masonry unit made from other materials, or made with other forming methods, or other means of binding the materials. 1.5 Three grades of brick are covered. 1.6 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. 1.7 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. 1.8 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.
