Foreword
This revised standard adopts ISO 1829. 1975 "General purpose tolerance zone selection," the technical content in line with international standards. consider
To our country, from the implementation of this standard experience and habits, as well as with the standard system of harmonized ISO GPS perspective, for the following
Some modifications.
--- The standard name be bootable elements. Geometrical product specifications (GPS);
--- Increased cooperation provisions;
--- Added Appendix A "nominal size to 500mm of priority, with the usual limit or gap limit interference";
--- Added Appendix B "nominal size greater than 500mm formulated with";
--- Added Appendix C "nominal size greater than 3150mm ~ 10000mm standard tolerances and fundamental deviations";
--- Added Appendix D "position in the GPS matrix model."
This standard replaces GB/T 1801-1999 "Limits and fits with tolerance and with the choice." Compared with the 1999 edition, the main changes
as follows.
--- The standard name be bootable elements. Geometrical product specifications (GPS);
--- Deleted introduction;
--- Increased Chapter 3 Terms and definitions;
--- "Basic size" to "nominal size"; on the deviation, lower deviation, maximum and minimum size limits were revised to limit the size of the pole
Limit deviation, lower limit deviations, limits on the size and the lower limit size;
--- Increase in Appendix D "position in the GPS matrix model."
This standard Annex A, Annex B, Annex C and Annex D are informative appendices. This standard GPS system location in the appendix
D is described.
The standard dimensions and geometry by the National Technical Committee of Standardization Technical specifications and centralized.
This standard was drafted. the machine Productivity Promotion Center, Zhejiang Asia-Pacific Electric Co., Ltd., Zhongyuan University of Technology, Xi'an Jiaotong University,
Zhengzhou University.
The main drafters of this standard. Lixiao Pei, Zhao Zexiang, Shi Ruikang, Zhao Zhuoxian, Zhang Linna, Qiaoxue Tao.
This standard replaces the standards previously issued as follows.
--- GB 1801-1979, GB 1802-1979;
--- GB/T 1801-1999.
