This standard specifies the test methods for pin size and geometric accuracy, and should be used in conjunction with corresponding product standards and basic standards. This standard gives items with two or more test methods and does not specify arbitration methods. If necessary, it should be agreed between the supplier and the buyer. This standard applies to pins specified in national standards and industry standards, and non-standard parts can also be used as a reference. Note: The size codes used in this standard, unless otherwise noted, are consistent with the product standards and basic standards.
