Annex ZZ
(informative)
Relationship between this European standard and the safety objectives
of Directive 2014/35/EU [2014 OJ L96] aimed to be covered
This European standard has been prepared under a Commission’s standardization request relating to
harmonized standards in the field of the Low Voltage Directive, M/511, to provide one voluntary means of
conforming to safety objectives of Directive 2014/35/EU of the European Parliament and of the Council of 26
February 2014 on the harmonization of the laws of the Member States relating to the making available on the
market of electrical equipment designed for use within certain voltage limits [2014 OJ L96].
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 ZZ.1 confers, within the limits of the scope of this
standard, a presumption of conformity with the corresponding safety objectives of that Directive, and
associated EFTA regulations.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60898-2 has been prepared by subcommittee 23E: Circuit-
breakers and similar equipment for household use, of IEC technical committee 23: Electrical
accessories.
This second edition cancels and replaces the first edition published in 2000 and
Amendment 1:2003. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) alignment with second edition of IEC 60898-1;
