GB9743-1997 |
This standard was revised to meet international economic, trade and scientific and technological exchanges and to accelerate my country's adoption of international standards and foreign advanced standards. There have been major changes in technical content:
The method of expressing tire specifications is the same as Equivalent to European standards. A T-level speed level has been added to the table of relationships between speed levels and the maximum driving speed of tires with different nominal rim diameters. Some tire specifications have been added to the \80" series, "75" series, "65" series and \60\ series. The tire specifications retained in the original standards and some bias car tire specifications that are no longer produced in China have been cancelled. . The appearance quality standard for car radial tires is cancelled, and the tire mileage guarantee clause is cancelled. In the technical requirements, the specific tire performance indicators and test methods are replaced by reference standards.
-In the basic parameter list, the use of K-type rims is cancelled, and the use of rims is basically set to the second gear. 1-Added the corresponding table of different air pressures and loads of car radial tires and the measured air pressure of car radial tires. Tires are listed as reserved production specifications. This standard will replace GB9743-88.GB1191-89 from the effective date. Appendix A of this standard is a reminder.
This standard is approved by the Ministry of Chemical Industry of the People's Republic of China. Proposed. This standard is under the jurisdiction of the National Tire Rim Standardization Technical Committee. The drafting organizations of this standard are: Beijing Rubber Industry Research and Design Institute of the Ministry of Chemical Industry, Liaoning Changzheng Tire Co., Ltd., and Shanghai Chint Rubber Factory. The main drafters of this standard are: Shen Jianrong, Chen Minling, and Ou Yanling. , Wang Kexian, Liu Shifang, Shan Jibao, Wang Jinlan. This standard was first released in January 1965 (the car radial tire part was first released in May 1988), and was first revised in October 1974 and March 1982. The second revision was in March 1989. This standard was entrusted to the National Tire and Rim Standardization Technical Committee for interpretation. 182
