1.1 本规范的目的是提供通过反射屋顶和墙壁的太阳辐射来减少建筑物太阳能增益的产品的一般要求。辐射控制涂层（RCC）是一种液体涂敷材料，可固化形成具有至少0.8太阳反射率和至少0.8环境温度红外发射率的固体涂层。 1.2 本规范涵盖了设计用于建筑外部应用的液体RCC的物理和机械性能。 1.3 以国际单位或英寸-磅单位表示的数值应单独视为标准值。每个系统中所述的值不一定精确相等； 因此，每个系统应独立于其他系统使用。合并两个系统的值可能会导致不符合标准。 1.4 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。 1.5 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 The purpose of this specification is to provide general requirements for products used to reduce solar gains on buildings by reflecting solar radiation from roofs and walls. Radiation Control Coating (RCC) is a liquid applied material that cures to form a solid coating having a solar reflectance of at least 0.8 and an ambient temperature infrared emittance of at least 0.8. 1.2 This specification covers the physical and mechanical properties of liquid-applied RCCs designed for exterior application for buildings. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems has the potential to result in non-conformance with the standard. 1.4 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. 1.5 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.
