Scope

This standard specifies the equipment, devices, and requirements for measuring the normal emissivity of spectrally selective absorbing coatings and the hemispherical emissivity of absorption coatings on all-glass vacuum solar collectors, as well as the sample size and requirements, test conditions, test procedures, and test methods.
This standard is applicable to the screening of process specifications and the measurement of the normal emissivity of materials and spectrally selective absorbing coatings during the development and production process, as well as the measurement of the hemispherical emissivity of absorption coatings on all-glass vacuum solar collectors.
