The upper standard adopts the national original standard S01253:1396% Machinery tire size and size S04259-2:99 Machinery The main differences between the American Tire Association's 2010 standard and the previous version of the standard GBT29-101 are: - the tire structure specification has been added, the tread depth has been set, the oblique tire section specification has been added, a small number of tire specifications that do not conform to the six standards have been removed, and the new tire load and air pressure have been specified, and the section width and the regulations after inflation have been cancelled. … The "standard tire", "allowed tire" and "allowed tire" in the table are replaced by "measured width". Added Chapter 1 Inner tube and belt, bottle standard, added "Use category content", replaced the "Classification" part in the original version of GB23-1. The difference between this standard and the international standard is as follows: - The format of group writing is appropriately adjusted, and the 70 series tire specifications that are not in the S (>4 wheel size) standard are compared with the allowable wheel size. This standard refers to the original version G20-19 to make up for the increase. A small number of specifications in the ISO cup standard are deleted. The design of the depth of the chemical groove is added. Appendix A and Appendix Symptom Tips of this standard are all recorded. From the implementation of this standard, it replaces GBT2930s sl,
Tire standard issued by the State Bureau of Petroleum and Chemical Industry Date: This standard is the National Tire Standardization Technical Committee, the standard is issued by Panzhou Tire Research Institute Co., Ltd., Sichuan Henan Energy Yi Co., Ltd. The main persons in charge of this standard are: Li Wenzheng, Xie Zhisai, Hu Zhi, the internal version, this standard was first issued in March 182 and first revised in November. This standard is the National Tire Standardization Technical Committee, CBT2980-2001
ISO Foreword
The International Organization for Standardization (ISO) is a federation of international standardization bodies (ISO member bodies) for worldwide use. Formulated by international society 1 The work is led by the Technical Committee of the S. All interested parties have the right to send representatives to attend the Technical Committee, and to cooperate closely with relevant international organizations, parties and non-partisans in this work. 1 The draft international standard formally adopted by the Technical Committee shall be circulated to the member bodies for voting. The international standard proposed by the group is less likely to require a vote by the group. The 1501250 standard for 190/1°C C31/SC6 tire and valve media technology page of this quarter's work This standard is only formulated in this state, the third edition is the 3rd edition, and the 2nd edition (IS 435; 1994) has been revised. The general title of TS (11250) is 1 Engineering tires and wheels.
