Announcement BJ42041-90
This standard specifies the terms, types, basic parameters and dimensions, technical requirements and markings and installation of thickness gauges. This standard is applicable to thickness gauges with a measurement range of 0.1mm, 0.01mm, 0.001mm and 0~1mm, 0~10mm, 0~20mm, and 30mm.
2 Definitions
This standard adopts the following definitions:
2. Thickness gauge
The thickness gauge is a kind of indicating gauge installed on a stand. The gauge is read by the measuring head and faces the measuring disk on the right. The displacement of the surface is used to measure the thickness of leather, building materials, plastics, etc. 2.2 Measuring depth 1
When measuring deep into the measured object, its center line will be the maximum distance to the measured edge (see Figure 1) 2.3 Indication error
The difference between the indicated value of the thickness gauge and the true value of the actual separation between the two measuring discs. 2.4 Indication variability
The maximum difference in the results when the same measured object is repeatedly measured without any change in the measuring conditions. Type, basic number and size
3.1 The type of the gauge is divided into type 1 and type 2. The type is shown in Figure 1 (only for explanation, not showing the specific structure). When the type 1 gauge is not in operation, the measuring head and the measuring station are in contact. When the type 2 gauge is not in operation, the measuring head and the measuring station are in contact. 3.2 The measurement and division values ​​of the thickness attenuation are shown in Table 11. Approved by the National Bureau of Machinery Industry J999-05-20, implemented on January 1, 2000. JB.T 10033-E999. 3.3 The recommended thickness gauge measuring surface diameter and measuring depth are shown in Table 2.

4.2 Under normal use, the movement of the measuring tool should be smooth and flexible, without stagnation. 4.3 The two measuring mothers of the serial scale should not have obvious misalignment. 4.4 The measurement of the type II thickness gauge should start from the end point of the required operation, and the overrun travel is shown in Table 3. 2
4.5 The width of the scale line on the dial is shown in Table 4.

Inspection Method
This appendix is ​​the test method for thickness gauges during delivery inspection and user acceptance. A1. Appearance
Use visual inspection.
AZ tide plate
Use tool microscopic inspection.
Surface roughness
Use surface roughness comparison sample for comparison inspection. A4 brush force
is tested by force gauge,
A5 indication error
is tested by inserting a gauge block between the two measuring blocks. The grade and nominal length of the gauge block are shown in Table A1. Table A?

Repeat the same measurement 5-10 times in each country and calculate the difference between the large and small indications of the measurement. A To determine the parallelism tolerance of the two measuring surfaces
Place the gauge blocks at the 1, 2, 3, 4 positions on the edge of the measuring surface (see Figure A "), and read the readings on the indicator respectively. The maximum and minimum values ​​of the readings are the parallelism tolerance of the two measuring surfaces.
