 adaption of the normative references and referring to ISO standards;
 consideration of revised type-A and type-B standards;
 moving of the list of significant hazards to an informative annex;
 modification of the safety requirements and protective measures by taking into consideration the
technological progress in the plastics and rubber industry and the continuous development of the
safety technology;
 modification of all annexes;
 fundamental modification of the annexes specifying the protective types and addition of further
examples of application;
 moving of the annex indicating the relationship between this European Standard and the Essential
Requirements of EU Directive 2006/42/EC to informative Annex ZA;
 cancellation of the annex indicating the relationship between this European Standard and the
Essential Requirements of EU Directive 98/37/EC.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For the relationship with EU Directive(s) see informative Annex ZA, which is an integral part of this
document.

Annex ZA
(informative)
Relationship between this European Standard and the essential
requirements of Directive 2006/42/EC aimed to be covered
This European Standard has been prepared under a Commission’s standardization request "M/396
Mandate to CEN and CENELEC for Standardisation in the field of Machinery" to provide one voluntary
means of conforming to essential requirements of Directive 2006/42/EC of the European Parliament
and the Council of 17 May 2006 on machinery, and amending Directive 95/16/EC (recast).
Once this standard is cited in the Official Journal of the European Union under that Directive,
compliance with the normative clauses of this standard given in Table ZA.1 confers, within the limits of
the scope of this standard, a presumption of conformity with the corresponding essential requirements
of that Directive and associated EFTA regulations.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).

Introduction
This document is a type-C standard as stated in ISO 12100:2010.
This document is of relevance, in particular, for the following stakeholder groups representing the
market players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine distributors, resellers, rebuilders and integrators;
— machine users/employers (small, medium and large enterprises);
— machine operators/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises).
The above-mentioned stakeholder groups have been given the possibility to participate in the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events
are covered are indicated in the Scope of this document.
When requirements of this type-C standard are different from those which are stated in type-A or
type-B standards, the requirements of this type-C standard take precedence over the requirements of
the other standards for machines that have been designed and built according to the requirements of
this type-C standard.

Plastics and rubber machines — Injection moulding
machines — Safety requirements
1 Scope
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.
