Foreword
In the light of the necessity to adapt EN 60335-2-79 with regard to the requirements of the Machinery
Directive 2006/42/EC, a draft was prepared by CENELEC TC61/WG6/J in co-operation with the
MD Consultant, taking also into account the results of CENELEC TC61/WG6 work on EN 60335-1.
The approach to amend EN 60335-2-79:2004 aiming toward listing the standard under the MD was
discussed and approved during the Kista meeting of CENELEC TC 61 in June 2008 (see
CLC/TC 61/SEC/1649), when it was decided to submit a draft for an amendment to the Unique
Acceptance Procedure.
The draft was circulated as FprAC in December 2008 and was approved by CENELEC as a new edition
of EN 60335-2-79 on 2009-09-01.
This European Standard supersedes EN 60335-2-79:2004 + A1:2006 + A2:2007.
In this European Standard the common modifications to the International Standard IEC 60335-2-79:2002
+ A1:2004 + A2:2007 are indicated by a vertical line in the left margin of the text.
The following dates are applicable:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2009-12-29
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2009-12-29
This Part 2 has to be used in conjunction with EN 60335-1, Household and similar electrical appliances –
Safety – Part 1: General requirements. It was established on the basis of the 2002 edition of that
standard. Amendments and revisions of Part 1 have also to be taken into account and the dates when
such changes become applicable will be stated in the relevant amendment or revision of Part 1.
This Part 2 supplements or modifies the corresponding clauses of EN 60335-1, so as to convert it into the
European Standard: Safety requirements for high pressure cleaners and steam cleaners.
When a particular subclause of Part 1 is not mentioned in this Part 2, that subclause applies. When this
standard states "addition", "modification" or "replacement", the relevant text of Part 1 is to be adapted
accordingly.
This European Standard has been prepared under a mandate given to CENELEC by the European
Commission and the European Free Trade Association and covers essential requirements of
EC Directive 2006/42/EC. See Annex ZZ.
NOTE 1 The following numbering system is used:
– subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1;
– unless notes are in a new subclause or involve notes in Part 1, they are numbered starting from 101, including those in a
replaced clause or subclause;
– additional annexes are lettered AA, BB, etc.;
– subclauses, notes and annexes that are additional to those in the IEC standard are prefixed with the letter Z.

Introduction
It has been assumed in the drafting of this European Standard that the execution of its provisions is
entrusted to appropriately qualified and experienced persons.
This standard recognizes the internationally accepted level of protection against hazards such as
electrical, mechanical, thermal, fire and radiation of machines when operated as in normal use taking into
account the manufacturer's instructions. It also covers abnormal situations that can be expected in
practice and takes into account the way in which electromagnetic phenomena can affect the safe
operation of machines.
This standard takes into account the requirements of IEC 60364 as far as possible so that there is
compatibility with the wiring rules when the machine is connected to the supply mains. However, national
wiring rules may differ.
If a machine within the scope of this standard also incorporates functions that are covered by another
Part 2 of EN 60335, the relevant Part 2 is applied to each function separately, as far as is reasonable. If
applicable, the influence of one function on the other is taken into account.
This standard is a product family standard dealing with the safety of machines and takes precedence over
horizontal and generic standards covering the same subject.
A machine that complies with the text of this standard will not necessarily be considered to comply with
the safety principles of the standard if, when examined and tested, it is found to have other features that
impair the level of safety covered by these requirements.
A machine employing materials or having forms of construction differing from those detailed in the
requirements of this standard may be examined and tested according to the intent of the requirements
and, if found to be substantially equivalent, may be considered to comply with the standard.
