Foreword
The text of document 61J/491/FDIS, future edition 3 of IEC 60335-2-72, prepared by SC 61J,
"Electrical motor-operated cleaning appliances for commercial use", of IEC/TC 61, "Safety of
household and similar electrical appliances" was submitted to the IEC-CENELEC parallel vote and
approved by CENELEC as EN 60335-2-72:2012.
A draft amendment, which covers common modifications to IEC 60335-2-72, was prepared by
CLC/TC 61, "Safety of household and similar electrical appliances" and approved by CENELEC.
The following dates are fixed:
• latest date by which this document has
(dop) 2013-05-03
to be implemented at national level
by publication of an identical
national standard or by endorsement
• latest date by which the national
(dow) 2015-05-03
standards conflicting with this document
have to be withdrawn
This document supersedes EN 60335-2-72:2009.
The principal changes in EN 60335-2-72:2012 as compared with EN 60335-2-72:2009 are as follows

– 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;
– the markings and instructions (Clause 7) have been revised basically;
– a new Annex DD 'Emission of acoustical noise' was added; and
– a new Annex EE 'Emission of vibration' was added.
This part 2 is to be used in conjunction with the EN 60335-1:2012 and its amendments.
NOTE 1 When “Part 1” is mentioned in this standard, it refers to EN 60335-1.
This part 2 supplements or modifies the corresponding clauses in EN 60335-1, so as to convert that
publication into the European Standard: Safety requirements for floor treatment machines with or
without traction drive, for commercial use.
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:

- 3 - EN 60335-2-72:2012
– 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.
Clauses, subclauses, notes, tables, figures and annexes which are additional to those in
IEC 60335-2-72:2012 are prefixed “Z”.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such
patent rights.
This document has been prepared under a mandate given to CENELEC by the European Commission
and the European Free Trade Association, and supports essential requirements of EU Directive(s).
For the relationship with EU Directive(s) see informative Annex ZZ, which is an integral part of this
document.
Endorsement notice
The text of the International Standard IEC 60335-2-72:2012 was approved by CENELEC as a
European Standard with agreed common modifications.
COMMON MODIFICATIONS
1 Scope
Add the following paragraph before the last one.
"This standard deals with the reasonably foreseeable hazards presented by machines that are
encountered by all persons.
However, in general, it does not take into account:
 children playing with the machine;
 the use of the machine by children;
 the use of the machine by vulnerable people or very vulnerable people.".
3 Terms and definitions
3.6.3
accessible part
Modification:
Delete “and probe 18”.
7 Marking and instructions
7.10 Delete the following paragraphs:
"Devices used to start/stop operational functions of the appliance, if any, shall be distinguished from
other manual devices by means of shape, or size, or surface texture, or position, etc.
An indication that the device has been operated shall be given by:
 A tactile feedback or
 An audible and visual feedback.

NOTE Z1 The sound of the motor or sound of an actuator switching ON/OFF is regarded as audible feedback. The stopping of
the typical function (e.g. stopping of the vibration on the body of the appliance or of a part of it) is regarded as tactile means.
NOTE Z2 Devices used to start/stop operational functions mean devices that are operated by the user to start/stop the
intended function of the appliance.
A selector switch with an off-position clearly identifiable is allowed.
An ON/OFF switch, if any, is considered a suitable device to stop operational functions. A plug is not
considered a suitable device to stop operational functions, as it can be difficult to be reached by
vulnerable persons.".
th
7.12 Add the following paragraph after the 4 one:
"Children should be supervised to ensure that they do not play with the appliance.".
Delete the paragraph beginning with “This appliance can be used…”.
7.12.Z1 Delete this paragraph.

40 kg are not tilted. Through openings, the test probe is applied to any depth that the probe will permit
and is rotated or angled before, during and after insertion to any position. If the opening does not allow
the entry of the probe, the force on the probe in the straight position is increased to 20 N. If the probe
then enters the opening, the test is repeated with the probe in the angled position.".
