illustrate:
1. The appendix of ISO 4759 “Fastener Tolerances” contains the test method standards for dimensional and geometric accuracy;
2. my country’s machinery industry standards have issued JB/T 9151.1 ~ JB/T
9151.7—1999 “Test methods for fasteners, dimensional and geometric accuracy” series of standards; (but geometric tolerances are no longer applicable)
3. The standard issued by this ministry adopts the Japanese JIS B1071-1985 “Test Method for Dimensional and Geometric Accuracy of Threaded Fasteners”.
The current JIS B1071-2010 version (the current version of the standard is more applicable to the rules of ISO 4759-11:2000).
4. The test method standards of the United States are all in the corresponding standards.
