Introduction
This document is a type C standard as stated in EN ISO 12100.
The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are
covered are indicated in the scope of this document.
When provisions of this type C standard are different from those which are stated in type A and B standards,

1 Scope
This European 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 not covered:
 machines on which the clamping unit can only be operated by the physical force of the operator;
 injection moulding machines with pneumatic drives for the platen movement;
 injection moulding machines with vertical platen movements driven by an electrical axis;
 blow moulding machines associated with an injection process (EN 422);
 machines for reaction injection moulding (RIM) (EN 1612-1);
 presses (EN 289);
 footwear moulding machines covered by EN 1845.
The safety requirements for the interaction between injection moulding machines and ancillary equipment are
specified.
This standard covers magnetic clamping systems only if:
 machines have horizontal clamping units; and
 the mould area is protected by guards; and
 such systems are delivered at the same time as the injection moulding machine by the machine
manufacturer.
This standard does not cover requirements for the design of an exhaust system.
