Withdrawn
A Withdrawn Standard is one, which is removed from sale, and its unique number can no longer be used. The Standard can be withdrawn and not replaced, or it can be withdrawn and replaced by a Standard with a different number.

Gives an accuracy system for corresponding flanks of individual cylindrical involute gears, and defines gear tooth accuracy terms, structure of gear accuracy system and allowable values of pitch deviations, total profile deviations and total helix of deviations. Applies to each individual element of a toothed wheel but not gear pairs as such.
