This standard specifies the test method for measuring the solar transmittance and absorptance of materials using a spectrophotometer. It is primarily applicable to materials and components used in the solar energy field, such as measuring the transmittance of the cover glass tube of an all-glass evacuated solar collector tube and the absorptance of its internal selective absorption coating. The core of the standard involves regulating the measuring instrument (spectrophotometer) and the test procedures to ensure the accuracy and comparability of the test results. Through spectral testing and specific calculation methods, the transmittance and absorptance of materials to solar radiation can be scientifically evaluated, which is crucial for assessing the thermal performance of products such as solar collectors and energy-saving building materials.
