modification.
Annex ZA
(informative)
Relationship between this European Standard and the Essential
Requirements of EU Directive 2006/42/EC
This European Standard has been prepared under a mandate given to CEN by the European Commission
and the European Free Trade Association to provide one means of conforming to Essential Requirements of
the New Approach Directive 2006/42/EC “Machinery safety”.
Once this European Standard is cited in the Official Journal of the European Union under that Directive and
has been implemented as a national standard in at least one Member State, compliance with the normative e
clauses of this International Standard confers, within the limits of the scope of this International Standard, a
presumption of conformity with the corresponding Essential Requirements of that Directive and associated
EFTA regulations.
WARNING — Other requirements and other EU Directives (e.g. 89/336/EEC “Electromagnetic
compatibility”) may be applicable to the products falling within the scope of this International
Standard.

ISO 23125:2010/Amd.1:2012(E)
Foreword
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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
Amendment 1 to ISO 23125:2010 was prepared by Technical Committee ISO/TC 39, Machine tools,
Subcommittee SC 10, Safety.
