IEC 60335-2-79:2002

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

Deals with the safety of high pressure cleaners for household, industrial and commercial use having a pressure not less than 2,5 MPa and not more than 25 MPa and with an input to the drive for the high pressure pump not exceeding 10 kW, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. It also applies to industrial and commercial steam cleaners even if the pressure is less than 2,5 MPa. It is also applicable to appliances making use of other forms of energy for the motor, but it is necessary that their influence is taken into consideration.

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
This part of International Standard IEC 60335 has been prepared by sub-committee 61J:
Electrical motor-operated cleaning appliances for industrial use, of IEC technical committee
61: Safety of household and similar electrical appliances.
This second edition cancels and replaces the first edition published in 1995 and its
amendment 1 (2000). It constitutes a technical revision.
The text of this standard is based on the following documents:
FDIS Report on voting
61J/128/FDIS 61J/133/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 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 fourth edition (2001) 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 electric high pressure
cleaners and steam cleaners.
– 4 – 60335-2-79  IEC:2002(E)
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:
– requirements: in roman type;
– test specifications: in italic type;
– notes: in small roman type.
Words in bold in the text are defined in Clause 3. When a definition concerns an adjective, the adjective and the
associated noun are also in bold.
The committee has decided that the contents of this publication will remain unchanged until
2004. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.
The following differences exist in the countries indicated below.
– Clause 1: Different pressure limitations apply (USA).
– 6.1: Ground fault current interrupters are required for appliances rated 250 V or less, single phase (USA).
– 11.101: The losses of burners are subject to regulations (Germany). Smoke spot requirements are different
(USA).
– 20.103: The fuel tank capacity is limited (USA).
– 21.101, 21.101.2 and 21.102: Different burner tests are required (USA).
– 25.7: Different power supply cord lengths are required (Canada, USA).
– Clause 32: The connection with the water mains is subject to regulations (Canada).
A bilingual version of this publication may be issued at a later date.

INTRODUCTION
It has been assumed in the drafting of this International 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 appliances when operated as in
normal use taking into account the manufacturer's instructions. It also covers abnormal
situations that can be expected in practice.
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 appliance is connected to the supply
mains. However, national wiring rules may differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 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 wi

This part of International Standard IEC 60335 has been prepared by sub-committee 61J:
Electrical motor-operated cleaning appliances for industrial use, of IEC technical committee 61:
Safety of household and similar electrical appliances.
This consolidated version of IEC 60335-2-79 consists of the second edition (2002)
[documents 61J/128/FDIS and 61J/133/RVD], its amendment 1 (2004) [documents
61J/165/FDIS and 61J/171/RVD] and its amendment 2 (2007) [documents 61J/252/FDIS and

The technical content is therefore identical to the base edition and its amendment and has
been prepared for user convenience.

convert that publication into the IEC standard: Safety requirements for electric high pressure
cleaners and steam cleaners.
When a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies

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:
– requirements: in roman type;
– test specifications: in italic type;
– notes: in small roman type.
Words in bold in the text are defined in Clause 3. When a definition concerns an adjective, the adjective and the
associated noun are also in bold.
