Belt drives — Pulleys — Quality, finish and balance

This International Standard specifies the characteristics of quality which are common to all transmission pulleys. It establishes specific quality levels for the finish and balance of transmission pulleys and test pulleys.

This International Standard is applicable to transmission pulleys for V-belts, V-ribbed belts, flat or synchronous belts; it does not apply to those pulleys for variable speed drives that have one or more moving flanges.

The other characteristics of transmission pulleys can be found in the relevant International Standards.
