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.
