BS EN ISO 20430 This document 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 document is applicable only 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 life cycle of the machinery (see ISO 12100:2010, 5.4). 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 can only be manually operated; injection blow moulding machines; machines for reaction injection moulding; compression moulding machines and transfer moulding machines; 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. NOTE Moulds and exhaust systems are not part of the machinery. This document is not applicable to injection moulding machines which are manufactured before the date of its publication.The emergency stop shall function as a category 0 or 1 stop as described in IEC 60204-1:2016, 9.2.2  ensuring the fastest stopping. Emergency stop devices shall be in accordance with ISO 13850:2015 and IEC 60204-1:2016, 10.7. An emergency stop device shall, at a minimum, be located at each operator station. Actuation of an emergency stop device shall stop any dangerous movement and shall discharge the hydraulic accumulators.Interlocking devices associated with guards shall fulfil the requirements of ISO 14119:2013, especially regarding the selection, arrangement and mounting. Reasonably foreseeable manipulation shall be prevented. Type 3 interlocking devices according to ISO 14119:2013 shall only be used if in the specific application they cannot be defeated. When a Type 3 or Type 4 interlocking device according to ISO 14119:2013 is used, it shall have two independent electrical contacts, and both shall be independently connected to the control and monitoring system.
