标准范围

确定要使用的接触式（触针）仪器的类型、使用建议、仪器校准程序及其特性验证。适用于在参考条件下获得的轮廓变换。测量轮廓的圆度偏差、程序、校准和旋转系统误差的测定分别在附录A至D中处理。附录E给出了绘制和读取极坐标图的规则。最小二乘中心的位置可通过附录F中给出的简单显式方程计算。

Establishes types of contact (stylus) instruments to be used, recommendations for their use, procedures for calibration of instruments and verification of their characteristics. Applies to a profile transformation, obtained under reference conditions. Departures from roundness of the measured profile, procedure, calibration and determination of systematic errors of rotation are dealt with in annexes A to D, respectively. Annex E gives rules for plotting and reading polar graphs. The position of the least squares centre can be calculated from a simple explicit equation given in annex F.
