Household and similar electrical appliances - Safety - Part 2-79: Particular requirements for high pressure cleaners and steam cleaners

This clause of Part 1 is replaced by the following. This International Standard deals with the safety of high-pressure cleaners without traction drive, intended for household and commercial indoor or outdoor use, having a rated pressure not less than 2,5 MPa and not exceeding 35 MPa. It also applies to steam cleaners and those parts of hot water high pressure cleaners incorporating a steam stage which have a capacity not exceeding 100 l, a rated pressure not exceeding 2,5 MPa and a product of capacity and rated pressure not exceeding 5 MPa?l. They are not equipped with a traction drive. The following power systems of the drive for the high pressure pump are covered: - mains powered motors up to a rated voltage of 250 V for single-phase machines and 480 V for other machines, - battery powered motors, - internal combustion engines, - hydraulic or pneumatic motors. This standard does not apply to - high pressure water jet machines having a rated pressure exceeding 35 MPa.

To točko 1. dela nadomešča naslednje besedilo. Ta mednarodni standard obravnava varnost visokotlačnih čistilnikov brez pogona za gospodinjsko in komercialno uporabo v prostoru ali na prostem z nazivnim tlakom najmanj 2,5 MPa in največ 35 MPa. Uporablja se tudi za parne čistilnike in tiste dele visokotlačnih čistilnikov na vročo vodo, ki vključujejo paro, s kapaciteto največ 100 l, nazivnim tlakom največ 2,5 MPa ter zmogljivostjo in nazivnim tlakom produkta največ 5 MPa/l. Aparati nimajo pogona. Standard zajema naslednje napajalne sisteme pogona za visokotlačno črpalko: – električne motorje z nazivno napetostjo največ 250 V za enofazne stroje in 480 V za druge stroje, – motorje na akumulatorje, motorje z notranjim zgorevanjem in – hidravlične ali pnevmatske motorje. Ta standard se ne uporablja za: – visokotlačne vodne stroje z nazivnim tlakom več kot 35 MPa.

Part 2-79: Particular requirements
for high pressure cleaners and steam cleaners

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 60335-2-79 has been prepared by subcommittee 61J: Electrical
motor-operated cleaning appliances for commercial use, of IEC technical committee 61:
Safety of household and similar electrical appliances.
This third edition cancels and replaces the second edition published in 2002 and its
Amendments 1 (2004) and 2 (2007). It constitutes a technical revision.
The principal changes in this edition as compared with the second edition of IEC 60335-2-79
are as follows (minor changes are not listed):
– the scope has been revised editorially to avoid misunderstandings;
– terms and definitions has been revised with regard to the requirements revised;
– the standard has been revised in general and updated regarding state-of-the-art, as far as
necessary, in particular some changes have been made to Clauses 15, 22, and 25;

– a new Annex CC 'Emission of acoustical noise' was added;
– a new Annex DD 'Emission of vibration' was added;
– a new Annex EE with a model test report for vibration emission was added.
The text of this standard is based on the following documents:
FDIS Report on voting
61J/485/FDIS 61J/497/RVD

Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its
amendments. It was established on the basis of the fifth edition (2010) of that standard.
NOTE 1 When “Part 1” is mentioned in this standard, it refers to IEC 60335-1.
This part 2 supplements or modifies the corresponding clauses in IEC 60335-1, so as to
convert that publication into the IEC 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
as far as is reasonable. When this standard states “addition”, “modification” or “replacement”,
the relevant text in Part 1 is to be adapted accordingly.
NOTE 2 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.
NOTE 3 The following print types are used:
