(Specification)Standard Specification for Interior Radiation Control Coating (IRCC) for Building Applications
Standard Specification for Interior Radiation Control Coating (IRCC) for Building Applications
SCOPE
1.1 This specification covers the classification, composition, and physical properties of an Interior Radiation Control Coating (IRCC) for use in building applications to reduce radiant heat transfer. The IRCC is sprayed, roller applied, or brushed onto interior building surfaces.
1.2 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.
1.3 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.
1.4 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.
