QB/T 1541-2005 Steel rods and wires for clocks

This standard will replace the light industry standard QB/T 1541-1992 "Steel bars and wires for clocks" issued by the former Ministry of Light Industry from the date of implementation. This standard is a revision of QB/T1541-1992 "Steel bars and wires for clocks". This standard specifies the classification, requirements, test methods, inspection rules and marking, packaging, transportation and storage of steel bars and wires for clocks. This standard is applicable to the daily machinery industry such as steel bars, wires, instruments and meters used in the manufacture of watch parts and can also be used as a reference.

4 Is the markup for QB:T1541-1992 Sterl bars and wires for locks? The main differences of this standard QR/T15411992 are as follows: cancel the common terminology; standardize the classification, specification and marking methods; cancel the uncommonly used specifications (4.2): the maximum limit of the shape, roundness and linearity of the material are adjusted according to the overall needs (4.3). This standard will be issued by the China Light Industry Association. This standard is the National Clock and Watch Standardization Center. |This standard is issued by the Industrial Clock and Watch Research Institute. The standard is mainly composed of Liu Kechong and Yang Du. The standard replaced by the standard version: QR8781983.QR/T1541-1992
