1.1 本规范涵盖了矿物纤维（岩石、矿渣或玻璃）半刚性和刚性板的分类、组成、尺寸和物理特性，用于在0°F（-18°C）和1800°F（982°C）之间的温度下工作的表面上作为隔热层。对于特定应用，供应商和买方应就实际温度限制达成一致。 1.2 为了获得令人满意的性能，应在低于环境温度的应用中使用正确安装的保护性蒸汽缓凝剂或屏障，以减少水通过绝缘层或其周围流向较冷表面的运动。 未使用蒸汽缓凝剂或屏障可能会导致绝缘和系统损坏。参考实践 C921 帮助材料选择。尽管蒸汽缓凝剂性能不属于本规范的一部分，但本规范中要求的性能 C1136 与应用程序或性能相关。 1.3 板内纤维的方向主要平行于主表面（面）。本规范不包括预制管道和储罐包裹隔热层，其中隔热层已切割和制造，以提供垂直于表面（表面）的纤维方向。 1.4 本标准无意提供小时额定消防系统的性能要求。有关适当的系统，请咨询制造商。 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。 1.7 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 the classification, composition, dimension, and physical properties of mineral fiber (rock, slag, or glass) semi-rigid and rigid board intended for the use as thermal insulation on surfaces operating at temperatures between 0°F (-18°C) and 1800°F (982°C). For specific applications, the actual temperature limits shall be agreed upon between the supplier and the purchaser. 1.2 For satisfactory performance, properly installed protective vapor retarder or barriers shall be used on below ambient temperature applications to reduce movement of water through or around the insulation towards the colder surface. Failure to use a vapor retarder or barrier can lead to insulation and system damage. Refer to Practice C921 to aid material selection. Although vapor retarder properties are not part of this specification, properties required in Specification C1136 are pertinent to applications or performance. 1.3 The orientation of the fibers within the boards is primarily parallel to the principal surface (face). This specification does not cover fabricated pipe and tank wrap insulation where the insulation has been cut and fabricated to provide a fiber orientation that is perpendicular to the surface (face). 1.4 This standard does not purport to provide the performance requirements of hourly-rated fire systems. Consult the manufacturer for the appropriate system. 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.
