BS EN 201:1997 4 © BSI 27 March 2006 0 Introduction This European standard is a type C standard as defined in EN 292-1:1991 and has been elaborated by CEN/ TC145/WG1. The extent to which hazards are covered is indicated in the scope of this standard. In addition, machinery shall comply, as appropriate, with EN 292 for hazards which are not covered by this standard. 1 Scope This standard specifies the essential safety requirements for injection moulding machines for the processing of plastics and/or rubber. All hazards listed in clause 4 are covered by this standard. The following machines are excluded: machines on which the clamping unit can only be operated by the physical force of the operator; machines for reaction injection moulding (RIM, see prEN 1612-1 and prEN 1612-2); compression and transfer moulding machines (see EN 289); direct on sole injection moulding machines and full boot injection moulding machines (Wellington type boots with textile inserts) (see prEN 1845). The safety requirements for the interaction between injection moulding machines and ancillary equipment are specified. The safety requirements for the ancillary equipment itself are not specified.
