This Standard provides guidelines for evaluating the uncertainty oftest values obtained when verifying dimensional measuring instruments 1 to an ASME B89 testingprotocol. The scope is limited to the case in which the test measur and is the error of indication at a rated operating condition; hence, test measurands such as the “worst possible” error of indication that might occur at any operating condition (including those conditions that are not tested) are outside the scope of this Standard.
