《GB/T 4380-1984确定圆度误差的方法两点、三点法》。
本标准规定了用两点、三点法测量来确定圆度误差值的一种方法，适用于测量零件内、外圆形要素的圆度误差。两点、三点测量得到的数值与实际的圆度误差值存在着差异，必须由本标准给出的反映系数进行修正。

Scope

This standard specifies a method to determine the roundness error value by two-point and three-point measurement, which is suitable for measuring the roundness error of the inner and outer circular elements of parts. There are differences between the values obtained by two-point and three-point measurement and the actual roundness error value, which must be corrected by the reflection coefficient given in this standard. The standards related to this standard are GB 1183-80 "Terms and Definitions of Shape and Position Tolerance" and GB 1958-80 "Regulations for Testing of Shape and Position Tolerance"
