##### scope:

This part of ISO 1328 establishes a System of accuracy relevant to corresponding flanks of individual cylindrical involute gears.

lt specifies appropriate definitions for gear tooth accuracy terms, the structure of the gear accuracy system and the allowable values of pitch deviations, total profile deviations and total helix deviations.

This part of ISO 1328 applies only to each element of a toothed wheel taken individually; it does not cover gear pairs as such.

lt is strongly recommended that any user of this part of ISO 1328 be very familiar with the methods and procedures outlined in ISO/TR 10064-1. Use of techniques other than those of ISO/TR 10064-1 combined with the limits described in this part of ISO 1328 may not be suitable.

Annex A gives formulae for tolerantes for tangential composite deviations which are also criterions of ISO quality, but are not mandatory inspection items.

Annex B provides values on profile and helix form and slope deviations which sometimes serve as useful information and evaluation values but are not mandatory inspection items.
