GB/T 14633-2010 Rare earth three-band phosphors for fluorescent lamps
Basic Information
Scope
This standard specifies the requirements, test methods, inspection rules, and marking, packaging, transportation, and storage of rare earth tri-primary phosphors for lighting applications.
This standard applies to phosphors obtained by high-temperature reaction, including yttrium oxide activated by europium, magnesium aluminate activated by terbium and cerium, and barium magnesium aluminate activated by low-valent europium (or low-valent europium and manganese), which emit red, green, and blue fluorescence respectively when excited by ultraviolet rays at 253.7 nm, as well as rare earth tri-primary phosphors for lighting applications composed of the aforementioned three phosphors in a certain proportion. They are mainly used in low-pressure mercury vapor fluorescent lamps.
