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:

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 and takes into account the way in which
electromagnetic phenomena can affect the safe operation of appliances.
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.
When a part 2 standard does not include additional requirements to cover hazards dealt with
in Part 1, Part 1 applies.
NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is
not necessary to specify particular requirements for the appliance in question over and above the general
requirements.
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they have been taken into
consideration when developing the general and particular requirements for the IEC 60335 series of standards. For
example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as
ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.
An appliance 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.
An appliance 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.

normal operation
conditions under which the machine is operated in normal use
It denotes the operation at rated flow and rated pressure with the appropriate nozzle and
hose line fitted, all strainers and filters in a clean operating condition and the unloader valve
set to the rated pressure. The water heater, if fitted, is operated at maximum power. Electric
motor driven machines are supplied at rated voltage.
Socket outlets for accessories are loaded with a resistive load in accordance with the
marking.
The burner is operated at rated power. Machines designed for operation at more than one
rated power setting are additionally tested at the most disadvantageous power.
On machines designed for use with a flue pipe, a section of flue pipe is attached to the
machine. Flue gas determinations are taken in this flue pipe.
The draught is adjusted as recommended in the instructions.
3.101
unloader valve
pressure operated device which, when the pump pressure exceeds a preset value, releases
the pressure and leads the excess fluid into the inlet system
In addition, it bypasses the total pump flow at reduced pressure when its outlet flow is cut off.
3.102
safety valve
pressure operated device which, when the pump or steam cleaner pressure exceeds a preset
value, releases the pressure and which may return the excess fluid or steam either to the inlet
system or into the atmosphere
3.103
rated pressure
maximum working pressure at the pressure generator during normal operation

without impairing its safety
3.105
rated flow
maximum flow at rated pressure at the nozzle during normal operation
3.106
maximum flow rate
highest possible flow rate at the nozzle
Note 1 to entry: Typically, the maximum flow rate occurs at working pressures lower than rated pressure and
with a nozzle designed for spraying of cleaning agents.
3.107
rated temperature
maximum temperature of the cleaning agent during normal operation
3.108
pressure switch
device which, in response to varying fluid pressure, provides a controlling function at a pre-set
value
