1.1 本实施规程供辐射屏障系统（RBS）的设计者、规范者、建造者和安装者使用，用于商业/工业建筑施工，不受其他限制。范围仅限于与RBS的使用和安装相关的说明，包括通常发射率为0.1或以下的表面，例如安装在基板上的金属箔或金属箔沉积物。本实践旨在解决的一些示例包括:（1）通风建筑围护结构空腔中的低发射率表面，用于延迟穿过空域的辐射传输:（2）内部建筑表面的低发射率表面，用于延迟向建筑居民或从建筑居民的辐射传输；以及（3）建筑物内部表面的低发射率表面，旨在减少辐射加热或冷却系统的辐射传递。 1.2 本规程涵盖了从安装前检查到安装后程序的安装过程。它不包括辐射屏蔽材料的生产。（见规范 C1313 .) 1.3 本规程无意取代制造商的安装说明，但应与此类说明一起使用。本惯例无意取代地方、州、联邦或国际规范。 1.4 本规程假设安装人员对安装辐射屏蔽材料所需的适用规范和法规、安全规程、工具、设备和方法具有良好的工作知识。它还假设安装人员了解影响RBS安装的商业/工业建筑施工的基本原理。 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。有关具体的预防说明，请参阅第节 5. 和 7. . 1.7 当安装或使用辐射屏蔽材料、附件和系统可能会造成安全或健康问题时，制造商应向用户提供与使用本公司产品相关的任何已知问题的适当当前信息，并应规定保护措施。 1.8 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。 ====意义和用途====== 4.1 在本实践中，人们认识到RBS的有效性、安全性和耐久性不仅取决于材料质量，还取决于正确安装。 4.2 RBS安装不当将降低热效率，引发火灾风险和其他不安全条件，并促进其安装结构的劣化。不当安装包括以下原因引起的火灾: (1) 嵌入式照明设备中的热量积聚， (2) 电气线路部件的劣化或故障，以及 (3) 由于水分积聚，木材结构劣化和油漆失效。 4.3 本规程为以安全有效的方式安装RBS产品提供了指导。现有建筑物的实际情况差异很大，应注意确保安全有效的安装。 4.4 在本实践中，提出了具有一般性和特殊性以及实用性的要求。 除非另有说明，否则不作为具体说明。用户应向制造商咨询应用和安装方法。本规程中的要求应为RBS的最低材料和安装要求。

1.1 This practice has been prepared for use by the designer, specifier, builder, and the installer of radiant barrier systems (RBS) for use in commercial/industrial building construction not otherwise restricted from use. The scope is limited to instruction relative to the use and installation of RBS, including a surface(s) normally having an emittance of 0.1 or less, such as metallic foil or metallic foil deposits, mounted on substrates. Some examples that this practice is intended to address include: (1) low-emittance surfaces in vented building envelope cavities intended to retard radiant transfer across the airspace: (2) low-emittance surfaces at interior building surfaces intended to retard radiant transfer to, or from, building inhabitants; and (3) low-emittance surface at interior building surfaces intended to reduce radiant transfer to, or from, radiant heating or cooling systems. 1.2 This practice covers the installation process from pre-installation inspection through the post-installation procedure. It does not cover the production of the radiant barrier materials. (See Specification C1313 .) 1.3 This practice is not intended to replace the manufacturer’s installation instructions but shall be used in conjunction with such instructions. This practice is not intended to supercede local, state, federal, or international codes. 1.4 This practice assumes that the installer possesses a good working knowledge of the applicable codes and regulations, safety practices, tools, equipment, and methods necessary for installation of radiant barrier materials. It also assumes that the installer understands the fundamentals of commercial/industrial building construction that affect the installation of RBS. 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. For specific precautionary statements see Sections 5 and 7 . 1.7 When the installation or use of radiant barrier materials, accessories, and systems has the potential to pose safety or health problems, the manufacturer shall provide the user appropriate current information regarding any known problems associated with the use of the product of the company and shall also specify protective measures. 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. ====== Significance And Use ====== 4.1 In this practice it is recognized that effectiveness, safety, and durability of an RBS depends not only on the quality of the materials, but also on proper installation. 4.2 Improper installation of an RBS will reduce the thermal effectiveness, cause fire risks and other unsafe conditions, and promote deterioration of the structure in which it is installed. Improper installations include fires caused by: (1) heat buildup in recessed lighting fixtures, (2) deterioration or failure of electrical wiring components, and (3) deterioration in wood structures and paint failure as a result of moisture accumulation. 4.3 This practice provides direction for the installation of RBS products in a safe and effective manner. Actual conditions in existing buildings vary greatly and care shall be taken to ensure safe and effective installation. 4.4 In this practice, requirements are presented that are both general and specific in nature and practical. They are not intended as specific instructions unless so indicated. The user shall consult the manufacturer for application and installation methods. The requirements in this practice shall be the minimum material and installation requirements for RBS.
