GB/T 25965-2010 Active
GB/T 25965-2010 Test methods of normal emittance of materials and hemispherical emittance of all-glass evacuated collector tubes
Abstract
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.
