This standard is based on the strength test part of the international standard 180101917 Passenger car tyre performance inspection-Indoor test method 3 (1993), and is equivalent to this international standard in terms of main technical contents.
By making the inspection of the quality and performance of light tires in line with international standards as soon as possible, in order to adapt to the needs of international standards as soon as possible, the technology and economy can be put into line with international standards. The differences between this standard and the original standard are as follows:
(1) In terms of technical requirements, the focus of the assessment is on radial tires, and the small damage performance of nylon and polyester bias-ply tires is assessed in the form of \note\ according to the standard radial tire assessment method. The original standard has changed the assessment method that gives equal emphasis to bias and radial tires. (2) The tires are divided into standard and enhanced types according to the nominal width, and different test pressures and minimum destructive energies are specified. (3) The requirement for correcting the air pressure during the test is added, and the provision that tubeless light tires are allowed to be installed with inner tubes for testing is added. (4) The provision that the point where the tire is not damaged and does not reach the specified minimum destructive energy value is added, is regarded as the point where the minimum destructive energy is recorded and not used as the average value. (5) The provision that when the automatic calculation of the destructive energy is used, the destructive energy should be stopped immediately when the specified value is reached. (6) The requirement that the destructive energy at all points in the original standard cannot be lower than the specified value of the minimum destructive energy is cancelled. (7) The legal unit of measurement for destructive energy is J (J). The differences between this standard and the international standard are as follows: (1) According to the national conditions, the installation requirements of the bias tires for passenger cars are added, and the standard type of radial tires for axle vehicles is added. Technical regulations, (2) This standard stipulates that the hemispherical diameter of the end of the tire head is ±0.5mm, and the inflation pressure deviation is ±10kPa: the hemispherical diameter deviation of the end of the tire head is ±1.6mm, and the inflation pressure deviation is ±15kPa. This standard will take effect from the date of entry into force, replacing GB/T450384. This standard is proposed by the Ministry of Chemical Industry of the People's Republic of China. This standard is under the jurisdiction of the Technical Committee for Standardization of Wheels and Rim. The initiating unit of this standard is Hualin Ji Ce Co., Ltd. The main drafters of this standard are: Wang Yanlin, Guan Jing. This standard was first issued in June 1984.
This standard committee is responsible for the technical committee for standardization of tires and rims. GR/T45031996
1SO) is a joint organization of the International Organization for Standardization (ISO) members of the world's standardization organizations. The work of formulating international standards is generally carried out through 1SD technical committees. For the needs of established technical committees, all professional organizations with a strong sense of professionalism have the right to send representatives to participate in the planning of the technical committee. International organizations (both foreign and non-European and European) may also participate in the planning of this work. In the interests of electrotechnical standardization, the 1S Corporation closely cooperates with the International Electrotechnical Commission (IEC) to coordinate technical standards. The technical committee is a two-way international standard. It must be issued to the member bodies for voting and publication. The international standard is a single standard with a small amount of installation fees and a small amount of installation fees. The international standard 1S0191 is established by TS (>/TC31/SC\China Wheel Valve\Technical Committee, "Passenger Car Tire and Wheel\Technical Zero Article". Appendix A is a part of the technical standard. For reference: 1 Scope

5.1.5 Re-adjust the tire pressure that has been stopped to the original specified value. 5.2 Test procedures
5.2.1 Place the tire prepared in accordance with 5.1 on the test machine and select approximately equal points along the center of the wheel surface for test.
5.2.2 Compact the tire surface and select the desired center line of the tread to avoid pressing into the groove. 5.2.3 Measure the pressure at each point before the wheel begins to break, the depth of pressure (stroke), or the time when the indenter touches the wheel edge and the stroke. Before the test, calibrate the air pressure at each point. 5.2.4 When the self-calculated destructive energy is used, when the specified minimum destructive energy is reached, stop the pressure head and continue to press into the tire. 5.2.5 If the pressure head touches the wheel steel, the tire is punctured, and the minimum destructive energy value is not reached, this point is the minimum destructive energy. During the test, if there is no inner tube and the inflation pressure cannot be maintained, the inner tube can be installed.
