Addendum modification of the teeth of cylindrical gears for speed-reducing and speed-increasing gear pairs

Attention is drawn to the fact that this Technical Report only regards recommendations which do not have any restrictive nature nor do they require the replacement of existing regulations which have proved their worth in the past. Applies only to external gear pairs with parallel axes of which the teeth of spur and helical gears are defined by the standard basic rack tooth profile in conformity with ISO 53.
