本标准旨在建立使用垂直或水平比较器和激光仪器测量给定公差的标准圆盘或圆柱形塞规的统一规程。本标准包括主盘或圆柱塞的几何质量要求、比较设备的重要特性、环境条件以及确保测量精度达到可接受水平的方法。本标准不涉及螺纹或齿轮测量线。

This Standard is intended to establish uniform practices for the measurement of master discs or cylindrical plug gages to a given tolerance using vertical or horizontal comparators and laser instruments. The Standard includes requirements for geometric qualities of master discs or cylindrical plugs, the important characteristics of the comparison equipment, environmental conditions, and the means to assure that measurements are made with an acceptable level of accuracy. This Standard does not address thread or gear measuring wires.
