Appendix A
(Appendix to the Standard)
Test Method for caliper gauge
This appendix is ​​about the test method for factory inspection of caliper gauge. A1 Indication Error
The indication error range of caliper gauge is measured by using the inner scale composed of outer diameter scale or 3-degree scale and disc block. When the two measuring surfaces of the caliper gauge are connected with the measuring surface of the micrometer or disc block clamp, the difference between the indication value on the dial indicator and the indication value of the outer diameter scale or the inner scale composed of the disc block is the indication error of the caliper gauge. This test should be carried out at least on four positions evenly distributed within the measuring range. The error test of the indication of the external caliper gauge is to place the level 3 piece between the two measuring surfaces of the external caliper gauge. The difference between the dial indicator indication and the monitoring scale is the error of the indication of the external caliper gauge. This test should be carried out at least on four positions evenly distributed within the measuring range. A2 Indication variability
The inspection of the indication variability is to perform repeated measurements on the measured value through numerical variation or measurement. The difference between the daily indication and the minimum indication is the indication variability of the caliper gauge. A3 Measuring force
The force of the caliper gauge is to use a force less than 0.1N to measure the force in the measuring range.
