QB/T1542—2005
This standard is a combination of QB/1542—1992 Clocks and Lead Copper Wire and Wire》QR/T1910-1993 Clothing Lead Yellow Clock Ladder and Wire. The main technical differences between QB/T1910-1993 and QB/T1992 are as follows: This standard combines the original contents of QF/T1542 into one standard: cancels the expression of the same technique: cancels the classification, specification, and marking methods of the specification, cancels the infrequently used specifications (37-4.2). According to the requirements of use, the material shape deviation, roundness, and direct load are adjusted. Adjustment (4.3) This standard is proposed by China Light Industry Federation. This standard is from the National Clock and Watch Standardization Center. This standard was drafted by the Light Industry Clock and Watch Research Institute. The main drafters of this standard are: Yue Zu, Yang Wamin. The previous versions of the standards replaced by this standard are: QB879-1983, QB/T1542-1992-QBB74-1983+QB/T1910-1993. This standard replaces the original light The light industry standard issued by the Ministry of Industry is QB/T1542-1992 Lead brass rods and wires for clocks and watches QB/T1910-1993 Lead brass rods and wires for watches and watches 3 Specifications
