Appendix A
(Standardized method)
Method for testing micrometers
This appendix is ​​about the test of micrometers for factory inspection. A1
1.1 Used to check the axial clearance of micrometers. If there is a problem, measure the axial clearance value on a special calibration fixture. 1,3 Use hand feeling to check the radial clearance of micrometers. If there is a problem, place the micrometer on a special calibration fixture and measure the radial clearance value 1mm from the end of the scale frame. 41,3 Use a Japanese dead-end tester or a measuring machine to check the two micrometers. There should be no obvious misalignment. If there is any objection, use a microscope to check the deviation of the two viewing surfaces according to the provisions of Table A1.4 Use a visual gauge or a table ruler to check the axial clearance A at the reverse connection between the micrometer vernier and the differential quotient. 5 Check the relative displacement of the micrometer vernier and the fixed pipe network in the circumferential direction. First tighten the micrometer screw, and turn the micrometer vernier with a slight force by hand. The difference in the readings of the positive and negative rotations is the relative displacement value A2. The line width can be measured by direct measurement on a microscope with differential measurement. 2.2 The line width difference can be checked by self-measurement. If there is any objection, check it on the microscope. A3 The correctness of each position
When the micrometer is zeroed, the overlap of the scale and tail scale on the vernier and the corresponding scale on the differential. When the micrometer is zeroed: use the eye or a five-fold magnifying glass to observe the fit of the scale and tail scale on the micrometer vernier and the corresponding scale on the differential quotient. If there is any abnormality, check it on the total microscope. A4 The hardness of the micrometer screw
should be checked at least 20m away from the measuring mother end face. A5 The flatness of the measuring surface
is determined by the optical wave interference method using a second-level flat crystal. A6 The flatness of the two measuring surfaces
JB/T10032—1999
Use four parallel flat products with a size difference equivalent to one-fourth of the distance between the micrometer end rod, and place them between the two measuring surfaces. Under the action of the micrometer T scale measuring force, the interference number detected on the two measuring surfaces is obtained, and the value with the largest number of interference drops is taken. A7 Indication error
For the micrometer, check the micrometer with a set of first-level precision defects corresponding to the scale series in Table A2, and measure the difference between the micrometer and the mother block size.

A8 Force and force change
Measure the force and force change of micrometer micrometer on the special dynamometer for micrometer: A9 Deformation of scale frame under force
Install and fix one end of the scale frame of micrometer micrometer vertically on the special tool on the flat plate. At this time, use the lever to touch the measuring plate surface to read the reading: then hang a 10N weight on the axis of the micrometer rod, and then read the reading on the lever and scale. The difference between the two readings is the deformation of the scale frame of micrometer.
