GB/T 2680-2021 Glass in building—Determination of light transmittance,solar direct transmittance,total solar energy transmittance,ultraviolet transmittance and related glazing factors
Abstract
This standard specifies the visible light transmittance, visible light reflectance, solar radiation flux, direct solar transmittance, direct solar reflectance, direct solar absorption, total solar transmittance, secondary heat transfer coefficient to the indoor side, shading coefficient, light-to-heat ratio, ultraviolet transmittance, emissivity, total solar infrared heat transmittance, and the measurement methods for related window glass parameters.
This standard applies to transparent materials such as single-pane glass and multi-pane windows.
