This part of ISO 1132 defines terms used in International Standards specifying tolerances for boundary dimensions, geometrical accuracy, running accuracy and internal clearance for rolling bearings. In addition, it specifies general conditions under which these tolerances apply and gives symbols for a number of the concepts defined.

Measuring and gauging principles and methods for assessing compliance with many of the definitions in this part of ISO 1132 are given in ISO/TR 9274.

ISO 5593 is a vocabulary of terms in the field of rolling bearings and, as such, is a valuable complement to this part of ISO 1132.
