This European Standard specifies the safety requirements for pressure metal diecasting units. It applies to pressure diecasting machines and to the interfaces with the following ancillary equipment: - die, - melting, holding and dosing furnaces (see EN 746-1), - metal feeding equipment, - inserting and removal devices, - spraying appliances, - heat exchanger for the die. This ancillary equipment itself is not covered. Additional risks arising from the material being cast are not covered. This standard does not apply to low pressure diecasting machines and/or gravity diecasting machines. This standard deals with all significant hazards, hazardous situations and events relevant to pressure diecasting machines when used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). It provides the requirements to be met by the manufacturer to ensure the safety of persons and property during transport, commissioning, use, de-commissioning and maintenance periods, as well as in the event of foreseeable failures or malfunctions that can occur in the equipment. This document is not applicable to pressure metal diecasting units/machinery which are manufactured before the date of its publication as EN.
