ASTM WK56365

    New Test Method for Measuring the Solar Heat Gain Coefficient of Fenestration Systems Using Calorimetry Hot Box Methods

    (What is a Work Item?)

    Developed by Subcommittee: C16.30 | Committee C16 | Contact Staff Manager


    1. Scope

    This test method provides requirements, guidelines, and specifies calibration procedures required for the measurement of the Solar Heat Gain Coefficient, SHGC, of fenestration systems and glazing systems installed in a solar calorimeter.

    This test method will be used by commercial testing laboratories and research laboratories to test the solar heat gain of fenestration products. The results will be used by consumers and researchers interested in evaluating and rating the solar heat gain of windows, doors and skylights.
