Part 2-72: Particular requirements for floor treatment machines
with or without traction drive, for commercial use
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 60335-2-72 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.

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.

HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –
SAFETY –
Part 2-72: Particular requirements for floor treatment machines
with or without traction drive, for commercial use
1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of powered ride-on and powered walk-
behind machines intended for commercial indoor or outdoor use for the following
applications:
– sweeping,
– scrubbing,
– wet or dry pick-up,
– polishing,
– application of wax, sealing products and powder based detergents,
– shampooing
of floors with an artificial surface.
Their cleaning motion is more linear than lateral or periodic.
NOTE 101 By contrast, the cleaning motion of machines covered by IEC 60335-2-67 is more lateral or periodic
than linear.
NOTE 102 This standard applies to machines for commercial use. The following list, although not
comprehensive, gives an indication of locations that are included in the scope:
– public use areas such as hotels, schools, hospitals;
– industrial locations, for example factories and manufacturing shops;
– retail outlets, for example shops and supermarkets;
– business premises, for example offices and banks;
– all uses other than normal housekeeping purposes.
They may be equipped with a traction drive system. The following power systems are
covered:
– internal combustion engines,
– mains powered motors up to a rated voltage of 250 V for single-phase appliances and
480 V for other appliances,
– battery powered motors.
Battery powered machines may be equipped with a built-in battery charger.
This standard does not apply to
– floor treatment appliances for household use according to IEC 60335-2-10;
– floor treatment machines for commercial use according to IEC 60335-2-67;
– spray extraction machines for commercial use (IEC 60335-2-68);
60335-2-72 © IEC:2012(E) – 9 –
– wet and dry vacuum cleaners, including power brush, for commercial use
(IEC 60335-2-69);
– road sweepers;
NOTE 103 In Europe, EN 13019 covers road sweepers.
– machines designed for use on slopes with a gradient exceeding 20 %;
– machines equipped with a power take-off (PTO);
– machines designed for use in corrosive or explosive environments (dust, vapour or gas);
– machines designed for picking up hazardous dusts (as defined in IEC 60335-2-69),
inflammable substances, or glowing particles;
– machines designed for use in vehicles or on board of ships or aircraft.
NOTE 104 Attention is drawn to the fact that
– in many countries additional requirements on the safe use of the equipment covered can be specified by the
national health authorities, the national authorities responsible for the protection of labour, the national water
supply authorities and similar authorities;
– ride-on machines designed for transport over public roads can be subject to additional requirements (e.g.
lighting, license plate etc.).

normal operation
conditions under which the machine is operated in normal use, as intended by the
manufacturer
It denotes the load corresponding to the rated power input or the highest obtainable load of
all particular loads of the various functions that can be operated at the same time in
accordance with the manufacturer’s instructions. For machines provided with a seat or an
operator platform, a mass of 75 kg secured in position at the appropriate height is used to
simulate the operator in the most unfavourable position.
Socket-outlets for accessories are loaded with a resistive load in accordance with the
marking.
Operational functions include all treatment and driving functions.
The normal operation related to the operational functions is specified in 3.1.9.101 to

pressed concrete paving slabs (see Annex AA) intermittently at least 30 min switched on, and
for a period of 5 min switched off.
An alternative is a smooth concrete area of a surface consistency comparable with
hydraulically pressed concrete paving slabs.
3.1.9.102 Polishing and dry buffing machines are operated as follows.
PVC- or comparable flooring surfaces are considered to be suitable for establishing normal
operation. The peak of input occurring during the drying process of the chemical applied to
treat the surface is not taken as normal operation but is averaged by extending
measurements over a period of at least 10 min.
3.1.9.103 Carpet shampooers are operated on a test surface consisting of a carpet, in
accordance with IEC 60312-1, the carpet being fastened to the floor.
Prior to testing, the brush of the shampooing machine is conditioned by operating it for 15 min
on a clean, dry concrete surface. After running on the concrete surface, the brush is
immersed in a shampoo solution for at least 30 min.
The solution tank is filled and the machine is operated over a period of 10 min.
