1.1 本规范涵盖了由硬质多孔玻璃组成的隔热砌块的一般要求，该隔热砌块用于建筑外墙和内墙、基础、地板、天花板和屋顶应用。绝缘块用于在200°F和−50°F（93.3°C和−45.6°C）。 1.2 本标准适用于商业上用于建筑外墙和内墙、基础、地板、天花板和屋顶施工的硬质泡沫玻璃隔热砌块产品。出于工程和设计目的，用户需要遵循砌块制造商提供的有关物理特性、系统设计注意事项和安装建议的特定产品信息。 1.3 本规范涵盖的隔热材料的使用通常由建筑规范或其他涉及防火性能的机构或两者共同规定。如有要求，应通过适当的管理文件规定的标准耐火试验方法来说明材料的耐火性能。 1.4 以英寸-磅单位表示的数值应视为标准值。括号中给出的值仅供参考。关于转换为本标准中包含的公制单位以外的其他公制单位，请参考IEEE/ASTM SI 10。 1.5 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。 1.6 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 the general requirements for thermal insulation block composed of rigid cellular glass intended for use in building exterior and interior walls, foundation, floor, ceiling, and roofing applications. The insulation blocks are intended for continuous use at temperatures between 200°F and −50°F (93.3°C and −45.6°C). 1.2 This standard is intended to apply to rigid cellular glass thermal insulation block products that are commercially useful in building exterior and interior walls, foundation, floor, ceiling, and roofing construction. For engineering and design purposes, users need to follow specific product information provided by block manufacturers regarding physical properties, system design considerations and installation recommendations. 1.3 The use of thermal insulation materials covered by this specification is typically regulated by building codes, or other agencies that address fire performance or both. Where required, the fire performance of the material shall be addressed through standard fire test methods established by the appropriate governing documents. 1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. For conversion to metric units other than those contained in this standard, refer to IEEE/ASTM SI 10. 1.5 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. 1.6 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.
