GB/T 3900—2003
This standard replaces GB/T39001997 Tire Valve Series". This standard adopts ISO 9413:1998 (Tire Valve Dimensions and Models) (English version). GB/T3900—2003
This standard is redrafted based on ISO 9413:1998. For the convenience of comparison, a comparison table of chapter and article numbers between this standard and the international standard is listed in Appendix C:11. The relevant technical differences between this standard and ISO 9413 have been abbreviated and marked with a vertical single line in the margin of the clauses to which they are related. A list of these technical differences and their reasons is given in the Appendix for reference. In order to facilitate use, this standard has also made the following formatting changes: a) "and international standards" was changed to "this standard"; b) the comma "" as a decimal point was replaced by ""; c) the foreword of the international standard was deleted.
The main differences between this standard and GB/T3900-1997 are: the product model marking of the valve has been revised (3.1 and 3.2 of the 1997 edition and 3.【 and 3.2 of this edition) + the specifications of the valve have been added and deleted (4 of the 1997 edition; 4 of the wooden version); the valve diagram and size marking have been revised (4 of the 1997 edition; 4 of this edition). The appendix of this standard Appendix A and Appendix B are normative appendices, and Appendix C, Appendix D and Appendix E are informative appendices. This standard is proposed by the China Petroleum and Chemical Industry Association. This standard is under the jurisdiction of the National Technical Committee for Tire and Rim Standardization. This standard is entrusted to the National Technical Committee for Tire and Rim Standardization for interpretation.
