Foreword
In the light of the necessity to adapt EN 60335-2-67 with regard to the requirements of the Machinery
Directive 2006/42/EC, a draft was prepared by CENELEC TC61/WG6/J in co-operation with the
MD Consultant, taking also into account the results of CENELEC TC61/WG6 work on EN 60335-1.
The approach to amend EN 60335-2-67:2003 aiming toward listing the standard under the MD was
discussed and approved during the Kista meeting of CENELEC TC 61 in June 2008 (see
CLC/TC 61/SEC/1649), when it was decided to submit a draft for an amendment to the Unique
Acceptance Procedure.
The draft was circulated as FprAB in December 2008 and was approved by CENELEC as a new edition
of EN 60335-2-67 on 2009-09-01.

Introduction
It has been assumed in the drafting of this European 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 machines 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 machines.
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 machine is connected to the supply mains. However, national
wiring rules may differ.
If a machine within the scope of this standard also incorporates functions that are covered by another
Part 2 of EN 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 with the safety of machines and takes precedence over
horizontal and generic standards covering the same subject.
A machine 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.
A machine 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.

Machines having a liquid container and provided with an appliance inlet are fitted with an appropriate
connector and flexible cable or cord; machines having a liquid container and type X attachment are fitted
with the lightest cross-sectional area specified in Table 11. Other machines are tested as delivered.
The liquid container of the machine is completely filled with a saline solution of water containing
approximately 1 % NaCl and a further quantity, equal to 15 % of the capacity of the container or 0,25 l,
whichever is the greater, is poured in steadily over a period of 1 min.
Hand-held appliances and machines that are unstable are then, with the container completely filled and
with the cover or lid in place, overturned from the most unfavourable of the normal positions of use, and
are left in that position for 5 min unless the machine returns automatically to its normal position of use.
Motorized cleaning heads of water-suction cleaning machines are placed in a tray, the base of which
is level with the surface supporting the machine. The tray is filled with the test solution to a level of 5 mm
above its base, this level being maintained throughout the test. The machine including the motorized
cleaning head is operated until its liquid container is completely full and afterwards for a further 5 min.
After each of these tests, the machine shall withstand the electric strength test of 16.3.
There shall be no trace of liquid on insulation that reduces the clearances or creepage distances below
the values specified in Clause 29.

15.3 Modification:
The relative humidity shall be (93 ± 6) %.
15.101 The insulation of motorized cleaning heads of water-suction cleaning machines shall be
resistant to the mechanical impact of picked up debris and sucked up liquids expected under normal use.
The following test is not applicable to motorized cleaning heads of class III construction having a
working voltage up to 24 V.
Compliance is checked by the following four tests.
The motorized cleaning head is subjected to an impact test as described in IEC 60068-2-75, the value
of the impact being 2 J. The motorized cleaning head is rigidly supported and three blows are applied to
every point of the enclosure that is likely to be weak.
It is then subjected to the free fall test procedure 1 of IEC 60068-2-32. It is dropped 4 000 times from a
height of 100 mm onto a steel plate having a thickness of not less than 15 mm. It is dropped
– 1 000 times on its right side;
– 1 000 times on its left side;
– 1 000 times on its front face;
– 1 000 times on its cleaning surface.
The motorized cleaning head is then subjected to the test described in 14.2.7 of IEC 60529, using the
test solution.
The motorized cleaning head shall then withstand the electric strength test of 16.3, the voltage being
applied between the live parts and the test solution. There shall be no trace of saline solution on
insulation that reduces the clearances and creepage distances below the values specified in Clause 29.
16 Leakage current and electric strength
This clause of Part 1 is applicable except as follows.
16.3 Addition:
Current-carrying hoses, except for their electrical connections, are immersed for 1 h in a saline solution of
water containing approximately 1 % NaCl, at a temperature of 20 °C ± 5 °C. While the hose is still
immersed, a voltage of 2 000 V is applied for 5 min between each conductor and all the other conductors
connected together. A voltage of 3 000 V is then applied for 1 min between all the conductors and the
saline solution.
17 Overload protection of transformers and associated circuits
This clause of Part 1 is applicable.
18 Endurance
This clause of Part 1 is not applicable.

20 Stability and mechanical hazards
This clause of Part 1 is applicable except as follows.
20.1 Addition:
Motorized cleaning heads are not subjected to this test.
20.2 Addition:
These requirements do not apply to rotating brushes and similar devices, or to moving parts exposed
during the fitting of accessories that allow conversion from one application to another.
20.Z101 Machines shall be provided with an OPC.
Compliance is checked by inspection and functional test.
20.Z102 Shaft ends and similar rotating parts shall be protected if they protrude by more than a quarter
of their diameter. Shafts up to 50 mm diameter do not need to be protected if they are rotating at less
than 5 revolutions per second and their ends are rounded and smooth.
The unintentional closing and lowering of doors, lids, covers etc., which could cause injury, shall be
prevented.
Machines heavier than 20 kg (empty) shall be equipped with wheels or rollers for transport, which shall be
located or protected so as to prevent injury to the feet of the operator.
Compliance is checked by inspection, by measurement and by functional test.

20.Z103 Vibration
The machine shall be designed and constructed in such a way that risks resulting from vibrations
produced by the machine are reduced to the lowest level, taking account of technical progress and the
availability of means of reducing vibration, in particular at source.
The handles shall be designed and constructed in such a way as to reduce the vibrations transmitted to
the upper limbs of the operator to the lowest level that is reasonably possible.
Compliance is checked by inspection.
20.Z104 Fuel tank
If a fuel tank is within or contiguous to the engine compartment and excessively high temperatures may
occur, the tank and/or filling arrangement shall be isolated from the electrical and exhaust systems by
suitable protection, e.g. a separate enclosure or baffles.
The tank location and facilities for filling shall be such that spillage or leakage will not drain onto electrical
or exhaust system parts.
Fuel spillage shall not be possible under normal operation.
Compliance is checked by inspection.
20.Z105 Internal combustion engine powered machines using liquefied petroleum gas
Internal combustion engine powered machines using liquefied petroleum gas (LPG) shall be constructed
in accordance with the additional requirements specified in Annex ZBB. Requirements for the LPG
container itself are not part of this standard.
Compliance is checked by inspection and by measurement.
21 Mechanical strength
This clause of Part 1 is applicable except as follows.
21.1 Replacement of the first paragraph:
Machines and their components and fittings shall have adequate mechanical strength and be constructed
to withstand such rough handling that may be expected in normal use, during transportation, assembly,
dismantling, scrapping and any other action involving the machine.
Modification in the third paragraph:
The impact value is increased to 1,0 J ± 0,04 J.
21.101 Those parts of the machine that are subjected to impact in normal use are tested as follows.
If failure of the part subject to impact would cause a failure to comply with this specification, any spot of
the machine that may be exposed during normal operation to impacts or blows shall be subjected to a
single blow with an impact energy of 6,75 Nm. The impact stress on the free-standing machines shall be
exerted by a steel sphere with a diameter of 50,8 mm and mass of 0,535 kg dropped from a height of
1,3 m or hanging on a string acting as a pendulum, falling from a height of 1,3 m.
