Description / Abstract:
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/laboratory and customer.
