This standard specifies the test methods for the size and geometric accuracy of pins and should be used in conjunction with the corresponding product standards and basic standards: For items that require two or more test methods, this standard does not specify an arbitration method. If necessary, an agreement between the supplier and the buyer should be reached. This standard is applicable to pins specified in national standards and industry standards. Non-standard parts can also be used as a reference. Note: The size codes used in this standard are consistent with product standards and basic standards, except for those otherwise specified. 2 References

· The test block and test method on the table
The manufacturing of the inspection tool should comply with
and be used for measurement. bzxz.net
If there is any dispute about the inspection information, check the radius [tolerance half of the diameter tolerance)
and use special equipment to compare the working diameter and the maximum diameter within the measurement range
Inspection
Use your hand to put the screw plug into the internal thread of the workpiece, and it should be able to pass through the inner thread of the light diameter
Use your hand to smooth the plug gauge inside the artificial sample, and then use a caliper to measure its diameter, the limit is less than or equal to 1.5P
The external thread is relatively light and small
Use your hand to put the adjustment ring into the external thread of the workpiece, and it should be able to pass through the external thread smoothly
method! ：
Use a non-slip smooth caliper to measure the external explosion effect of the test part. Do not pass through 21
Use an outside diameter bisecting ruler to measure the length (ton component) in two mutually perpendicular true diameter directions of the test part.
Use a 0.05mm caliper to measure
For the measurement of the parallel pin, a ring gauge with an aperture equal to the nominal vertical diameter should be used to measure the neck of the cotter pin, and then use a caliper to measure the true component of the short leg ring gauge side.

Method 3
Use a dial indicator [sheet measuring head] to measure the remaining method 3:
Use a special pass and stop gauge to measure the plate
Be careful of the length of the plate
Light the end thread ring gauge to 1, and then use a 0.05mm caliper to measure the depth of the pro-fuel efficiency ring gauge from the end.
First screw the pro-fuel efficiency ring gauge into the end hole, and then use a 0.05mm caliper to measure the height of the planer
Aperture 4
Method 1:
Measure with a 0.02mm caliper
Method 2: Use a stopper and smooth plug gauge to measure
Method 1: First, place the special pin that matches the hole diameter specification into the manhole, and then use a 0.0mm caliper to measure (single hole minus the middle diameter, double hole minus the pin diameter). Method 2: Use a (.05mm) caliper to measure the head diameter. Use a 0.02mm caliper to measure the head separation. Use a 0.02mm caliper to measure the opening of the gland and the distance between the two feet. Special quantity method 1: The special research should be able to pass through the method 2: Measured with a 0.02mm caliper, the calorific value should not be greater than the value of d and d. The opening angle of the opening should be convex. Measured with a special angle pressing plate. The regulations of GB/T1957 and the provisions of GB/T 3934.
