Application Summary AI generated
This standard specifies test methods for measuring key optical and thermal properties of glass used in building construction, including visible light transmittance, solar direct transmittance, total solar energy transmittance, and ultraviolet transmittance. It is applied in the quality control and performance evaluation of architectural glass products, such as windows, curtain walls, and glazing systems, to assess their energy efficiency and solar control characteristics. The standard is used by manufacturers, testing laboratories, and building material specifiers to ensure compliance with building energy conservation requirements.
