HG/T2442--2001
This standard is a revision of the chemical industry standard HG/T2442-1993 "Washing Machine V-Belt". The main technical differences between this standard and HG/T2442-1993: the flexural performance is removed.
- The requirements for all dimensional deviations of washing machine V-belts are stricter than those of HG/T2442-1993. - The dynamic performance requirements for the cord adhesion strength test and the fatigue life test on a dedicated fatigue testing machine are added. This standard replaces HG/T2442-1993 from the date of implementation. This standard was proposed by the Policy and Regulations Department of the former State Administration of Petroleum and Chemical Industry. This standard is under the jurisdiction of the chemical industry tape standardization technical centralized unit. The drafting units of this standard: Hebei Huanyu Rubber Factory, Qingdao Rubber Industry Research Institute. The main drafters of this standard: Wang Huamin, Gao Fengxian, Han Deshen, Xin Yonglu. 339
