Measurement of Plain Internal Diameters for Use as Master Rings and Ring Gages
|Publication Date:||1 January 2002|
This Standard is intended to establish uniform practices for the measurement of master rings or ring gages using horizontal methods. The standard includes requirements for geometric qualities of master rings or ring gages, 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 include measurement methods for rings below 1
mm (0.040 in.). The
measurement method on these very small rings should be agreed upon
prior to manufacture or
calibration between the manufacturer/laborat
