This second edition cancels and replaces the first edition (1976). Establishes a method of calculating minimum pulley diameters. Applies to belts made of rubber or plastics with textile or metal carcasses. Is not applicable to belts which have a carcass thickness of more than 20 mm or to those which have intermediate lyers of rubber or plastics of more than 0,8 mm thickness between the plies, and not applies to heat-resistant belts for hot products over 100 °C or to belts in service at temperatures under -40 °C.
