Scope
This standard specifies the classification and conversion factors for the complexity of steel free forgings on hydraulic presses.
This standard applies to steel forgings produced by the free forging method on hydraulic presses. This standard can be used as a basis for calculating the standard output of forgings, energy consumption, and establishing labor quotas, and can also serve as a reference for setting trade prices.
