1.1 本规范涵盖标称均匀厚度（非锥形）和纹理的纤维水泥瓦、奶昔和板条（屋顶产品），包括设计用于在建筑物屋顶上提供暴露在天气中的表面的配件。 1.2 本规范不适用于非石棉纤维水泥屋面板、木瓦和设计不同剖面和厚度的石板（规范 C1530 )，刨花板（术语 D1554 )，或水泥粘合刨花板（规范BS 5669:第4部分）和（ISO 8335）。 1.3 本规范不包括产品安装或已安装系统性能的详细信息。有关正确的安装说明，请参阅制造商的安装文献，参见规范 C1459 屋顶系统性能和试验方法 E108 耐火等级。 1.4 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。 1.5 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 fiber-cement shingles, shakes, and slates (roofing products) of nominally uniform thickness (non-tapered) and texture, including accessories designed to provide the weather-exposed surfaces on roofs of buildings. 1.2 This specification is not applicable to non-asbestos fiber-cement roofing shakes, shingles, and slates with designed varying profiles and thicknesses (Specification C1530 ), particle board (Terminology D1554 ), or cement-bonded particleboards (Specification BS 5669: Part 4) and (ISO 8335). 1.3 This specification does not include details of product installation or installed system performance. Refer to the manufacturer's installation literature for proper installation instructions, to Specification C1459 for roofing systems performance, and to Test Methods E108 for levels of fire resistance. 1.4 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. 1.5 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.
