1.1 本规程供建筑施工中使用的内部辐射控制涂层系统（IRCC）的设计者、规范者和施涂者使用。本范围包含与喷涂、轧制或刷涂IRCC的使用和安装相关的说明。本实践旨在解决的示例包括:( 1. )通风建筑围护结构空腔中的低发射率表面，旨在延缓穿过通风空间的辐射传输；( 2. )建筑内部表面的低发射率表面，旨在阻止辐射向建筑居民转移或从建筑居民转移； 和( 3. )建筑内部表面的低发射率表面旨在减少加热或冷却系统之间的辐射传递。 图1 典型住宅用途 注1: 应用IRCC覆盖外露屋顶板区域，包括直接连接到屋顶板的支撑结构（如檩条、椽子和桁架上弦）。IRCC的低发射度表面必须面向阁楼内部。 图2 典型的工业、商业和农业用途 注1: 应用IRCC覆盖整个内表面区域。IRCC的低发射率表面必须面向建筑物内部。 1.2 本规程涵盖了从安装前检查到安装后的安装过程。它不包括内部辐射控制涂层材料的生产。 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、州或联邦法规。 1.4 本规程假设安装人员对安装内部涂层材料所需的应用规范和法规、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IRCC安装的建筑构造的基本原理。 1.5 当内部辐射控制涂层材料、附件和系统的安装或使用造成安全或健康问题时，制造商应向用户提供与产品预期用途相关的任何已知问题的适当当前信息，并应提供安全使用保护措施的指导。用户应制定适当的安全和健康实践，并在使用前确定监管要求的适用性。 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。 具体的预防说明包含在章节中 5. 和 7. . 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。 ====意义和用途====== 4.1 该实践认识到IRCC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 IRCC安装不当将降低其热效率，导致火灾风险和其他不安全条件，并促进其安装结构的劣化。不正确的安装可能会产生特定的危险，包括:嵌入式照明设备中的热量积聚、电线组件故障的恶化、木材结构的恶化以及由于水分积聚而导致的油漆故障。 4.3 本规程为以安全有效的方式安装IRCC材料提供了指导。现有建筑物的实际情况将有很大差异。 4.4 用户应向制造商咨询应用和安装方法。

1.1 This practice has been prepared for use by the designer, specifier, and applicator of Interior Radiation Control Coating Systems (IRCCS) for use in building construction. The scope contains instructions related to the use and installation of IRCCS that are sprayed, rolled, or brush applied. 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 vented airspace; ( 2 ) low emittance surfaces at interior building surfaces intended to retard radiant transfer to or from building inhabitants; and ( 3 ) low emittance surfaces at interior building surfaces intended to reduce radiant transfer to or from heating or cooling systems. FIG. 1 Typical Residential Use Note 1: Apply IRCCS to cover the exposed roof deck area including support structure directly connected to the roof deck (such as purlins, rafters, and top chord of the trusses). The low-emittance surface of the IRCCS must face the interior of the attic. FIG. 2 Typical Industrial, Commercial, and Agricultural Use Note 1: Apply the IRCCS to cover the entire interior surface area. The low-emittance surface of the IRCCS must face the interior of the building. 1.2 This practice covers the installation process from pre-installation inspection through post-installation. It does not cover the production of the Interior Radiation Control Coating Materials. 1.3 This practice is not intended to replace the manufacturer's installation instructions, but it shall be used in conjunction with such instructions. This practice is not intended to supersede local, state, or federal codes. 1.4 This practice assumes that the installer possesses a good working knowledge of the application codes and regulations, safety practices, tools, equipment, and methods necessary for the installation of Interior Coating Materials. It also assumes that the installer understands the fundamentals of building construction that affect the installation of an IRCCS. 1.5 When the installation or use of Interior Radiation Control Coating Materials, accessories, and systems pose safety or health problems, the manufacturer shall provide the user appropriate current information regarding any known problems associated with the intended use of the products and shall also provide direction on protective measures to be employed for safe utilization. The user shall establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use. 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. Specific precautionary statements are contained in Sections 5 and 7 . 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. ====== Significance And Use ====== 4.1 This practice recognizes that effectiveness, safety, and durability of an IRCCS depends not only on the quality of the materials, but also on the proper installation. 4.2 Improper installation of an IRCCS will reduce its thermal effectiveness, cause fire risks and other unsafe conditions, and promote deterioration of the structure in which it is installed. Improper installation has the potential to create specific hazards that include: heat buildup in recessed lighting fixtures, deterioration of failure of electrical wiring components, and deterioration of wood structures and paint failure due to moisture accumulation. 4.3 This practice provides directions for the installation of IRCCS materials in a safe and effective manner. Actual conditions in existing buildings will vary greatly. 4.4 The user shall consult the manufacturer for application and installation methods.
