Specifies safety requirements for the design, construction, operation and maintenance of power stamping presses and brake presses. It incorporates the details for the safeguarding of power presses, die design and die setting, and provides appropriate recommendations for the operation, inspection and maintenance of presses, and the training and supervision of operators.

This Standard specifies particular safety requirements for the design, construction, operation and maintenance of power stamping presses and brake presses. It incorporates the details for safeguarding, die design and die-setting, and provides appropriate recommendations for operation, inspection, and maintenance of presses, and training and supervision of operators. This Standard does not cover hot-metal presses, guillotines, shearing machines, roll-forming machines, forge hammers or forge presses, bulldozers, upsetters, injection moulding or die-casting equipment.
