1.1 本规范涵盖了厚度和质地均匀或不均匀的非石棉、纤维增强水泥、木瓦和板岩屋顶系统的性能。 1.2 本规范不包括产品安装和工艺的详细信息。应参考制造商的安装说明，了解斜坡、夹层、垫层、护套要求、暴露、紧固件以及维修或更换说明等详细信息。 1.3 本规范不涉及规范中涵盖的单个摇木、木瓦和板岩产品的要求 C1225 和 C1530/C1530米 。 1.4 本规范中包含的试验旨在作为屋顶系统的鉴定试验。 超出制造商质量控制规范允许范围的产品配方、设计或制造过程的变更，应要求随后的系统重新测试或独立测试机构的书面同意，以确保配方、设计和制造过程的变化不会损害系统性能。 1.5 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。 1.6 本标准并不旨在解决与其使用相关的所有安全问题（如有）。 本标准的使用者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。 1.7 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 the performance of non-asbestos, fiber-reinforced cement shake, shingle, and slate roofing systems that are of uniform or nonuniform thickness and texture. 1.2 This specification does not include details of product installation and workmanship. The manufacturer's installation instructions shall be referred to for details such as slope, interlayment, underlayment, sheathing requirements, exposure, fasteners, and repair or replacement instructions. 1.3 This specification does not address requirements for individual shake, shingle, and slate products, which are covered in Specification C1225 and C1530/C1530M . 1.4 The tests contained in this specification are intended as qualification tests for a roofing system. Changes in product formulation, design, or manufacturing process beyond the ranges allowed in the manufacturer's quality control specifications, shall require subsequent system retesting or written concurrence by an independent testing agency that the changes in formulation, design, or manufacturing process will not be detrimental to system performance. 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 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. 1.7 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.
