ASTM C1483-04

Standard Specification for Exterior Solar Radiation Control Coatings on Buildings

ABSTRACT
This specification provides the general physical and mechanical requirements for liquid-applied exterior solar radiation control coatings designed for exterior application on buildings or other structures for the purpose of reducing thermal loads on buildings by reflecting solar radiation from roofs and walls. The specification also includes the testing procedures by which the acceptability of the material may be determined. The physical and mechanical properties to which the coatings shall be tested and accordingly adhere to are total solid weight, solid volume, solar reflectance, infrared emittance, elongation, adhesion, water vapor permeance, flame retardancy, fungi resistance, water absorption, cured sample thickness, and outdoor durability.
SCOPE
1.1 The purpose of this specification is to provide general requirements for products used to reduce thermal loads on buildings by reflecting solar radiation from roofs and walls. Radiation control coating (RCC) is a liquid applied coating having a solar reflectance of 0.8 and an ambient temperature total hemispherical emittance of at least .08.
1.2 This specification covers the physical and mechanical properties of liquid-applied radiation control coatings (RCCs) designed for exterior application on buildings or other structures, where ambient air temperatures range form -34 to 54oC (-30 to 130oF). The specification also includes the testing procedures by which the acceptability of the material may be determined.
1.3 The products that comply with this specification may be used for other applications and have other properties not covered by this specification. In such cases, it is advisable to check other specifications that address the applications of interest.
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 and health practices and determine the applicability of regulatory limitations prior to use.
