    Abstract - (Show below) - (Hide below)

    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.
