ASTM WK41848

    New Practice for Simulated Field Exposure of Roofing Materials for Determination of Solar Reflectance and Thermal Emittance

    (What is a Work Item?)

    Developed by Subcommittee: D08.20 | Committee D08 | Contact Staff Manager



    WK41848

    1. Scope

    1.1 D-XXXX applies to testing the effect of simulated field exposure on the solar reflectance and thermal emittance of all roofing materials. The solar reflectance and thermal emittance of roofing materials are changed by exposure to the outdoor environment. These changes are caused by three factors: deposition of pollutants, microbiological growth, and change in physical or chemical properties. This practice applies to preparing samples for measuring the changes in solar reflectance and thermal emittance caused by simulated deposition of airborne pollutants. Exception: This practice shall not be applied to materials whose physical or chemical properties are designed to grossly change within three years of natural exposure. An example of such a material would be a metal panel with a temporary polymer coating.
