Scope
GB/T 40563-2021 is the English-translated version of 氟化物红色荧光粉.
GB/T 40563-2021 is the Chinese product standard for fluoride red phosphors activated with manganese, the conversion materials excited by the light of LEDs and other light-emitting devices.
It sets out product specifications and requirements, test methods, inspection rules and the marking, packaging, transport, storage and quality certificate.
The tests draw on national methods for particle size distribution, specific surface area, density, spectral performance, chromaticity coordinates, thermal quenching and quantum efficiency of phosphors.
Its definitions include chromaticity coordinates, calculated according to the CIE 1931 standard observer, and the excitation wavelength. It was issued on 11 October 2021 and has applied since 1 May 2022.
