QET2514—2001
This standard is in compliance with the special standard Z3K70007-189 Glass tubes for electric light sources issued by the Ministry of Light Industry. (The document was published by the Light Industry Commission in 19912 and the number is B3578-1999, the same as before) This revision has been revised and improved, and the glass tube system for lamps has been added. There are many products of electric light sources, and the quality of the products is also many. There are problems that have not been revised in this revision. The supply and demand parties can make their own references to the relevant standards on the material issues. This standard is proposed by the General Business Department of the Light Industry Federation. The technical standard is proposed by the Light Source Standardization Center of China. The drafter of this standard is Liu Maxi and Li Yanhai. The national light industry standard BT3578-1999 is a national standard for glass tubes and installations for high-quality lamps.
