This International Standard specifies the essential safety requirements for the design and construction of injection moulding machines for the processing of plastics and/or rubber and provides information for their safe use. This standard is only applicable to injection moulding machines with hydraulic and/or electrical drives for platen movement. This document deals with all significant hazards, hazardous situations and events relevant to injection moulding machines, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex A) during the foreseeable lifetime of the machinery, including transportation, assembly, commissioning, use, maintenance, dismantling, disabling and scrapping. This standard covers safety requirements and/or protective measures related to the integration of ancillary equipment. The following are not covered: machines on which the clamping unit can only be operated by the physical force of the operator; machines for which the hydraulic jack is manually operated; injection blow moulding machines; machines for reaction injection moulding; compression moulding machines and transfer moulding machines for plastics and rubber; direct-on sole moulding machines, unit sole and footwear component moulding machines, full shoe and boot moulding machines; design of an exhaust system; design and construction of the mould. This standard is not applicable to injection moulding machines which are manufactured before the date of its publication.
