The power input of motorized cleaning heads is measured separately.
15 Moisture resistance
15.2 Replace the text after note 101 by the following:
Nozzles and motorized cleaning heads of water-suction cleaning appliances are placed in
a container, the base of which is level with the surface supporting the appliance. The
container is filled with a detergent solution to a level of 5 mm above its base, this level being
maintained throughout the test.
The solution consists of 20 g of NaCl and 1 ml of a solution of 28 % by mass of dodecyl
sodium sulphate in each 8 l of water.
The appliance is operated until its liquid container is completely full and for a further 5 min.
NOTE 102 The solution should be stored in a cool atmosphere and used within seven days of its preparation.
NOTE 103 The chemical designation of dodecyl sodium sulphate is C12H25NaSO4.
NOTE 104 If it is not possible to overfill the container for soiled liquid owing to the construction of the appliance,
the test specified in 19.101 is considered to be adequate.

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

The motorized cleaning head is then subjected to the test described in 14.2.7 of IEC 60529,
the water containing approximately 1 % NaCl.
The motorized cleaning head shall then withstand the electric strength test of 16.3, the
voltage being applied between the live parts and the solution, and inspection shall show that
there is no trace of saline solution on insulation which could result in a reduction of
clearances and creepage distances below the values specified in Clause 29.
NOTE The test is not carried out on motorized cleaning heads of class III construction having a working
voltage up to 24 V.
16 Leakage current and electric strength
Add the following subclause:
16.3 Addition:
Current-carrying hoses, except for their electrical connections, are immersed for 1 h in 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.
19 Abnormal operation
19.1 Add the following new paragraph:
The test of 19.7 is only carried out on motorized cleaning heads.
19.7 Replace the existing text with the following:
Motorized cleaning heads are tested with the rotating brush or similar device locked for
30 s.
20 Stability and mechanical hazards

20.1 Addition:
NOTE 101 Motorized cleaning heads are not subjected to this test.
20.101 Shaft ends and similar rotating parts shall be protected if they protrude by more than
a quarter of their diameter, unless the end is rounded and less than 50 mm in length.
Injury due to unintentional closing or slamming of parts, such as movable side walls and
covers, shall be prevented.
Wheels or rollers for the transport of appliances heavier than 20 kg shall be located or
protected so that injury to the feet of the operator is prevented.
Compliance is checked by inspection, by measurement and by manual test.

21 Mechanical strength
Add the following new subclauses:
21.102 Current-carrying hoses shall be resistant to crushing.
Compliance is checked by the following test.
The hose is placed between two parallel steel plates each having a length of 100 mm, a width
of 50 mm and the edges of the longer sides rounded with a radius of 1 mm. The axis of the
hose is positioned at right angles to the longer sides of the plates. The plates are placed at a
distance of approximately 350 mm from one end of the hose.
The steel plates are pressed together at a rate of 50 mm/min ± 5 mm/min until the applied
force is 1,5 kN. The force is then released and the electric strength test of 16.3 is carried out
between the conductors connected together and the saline solution.
21.103 Current-carrying hoses shall be resistant to abrasion.
Compliance is checked by the following test.
One end of the hose is attached to the connecting rod of the crank mechanism shown in
Figure 102. The crank rotates at 30 revolutions per minute resulting in the end of the hose
moving horizontally backwards and forwards over a distance of 300 mm.
The hose is supported by a rotating smooth roller over which a belt of abrasive cloth moves at
a speed of 0,1 m/min. The abrasive is corundum grit size P 100, as specified in ISO 6344-2.
A mass of 1 kg is suspended from the other end of the hose, which is guided to avoid rotation.
In the lowest position, the mass has a maximum distance of 600 mm from the centre of the
roller.
The test is carried out for 100 revolutions of the crank.
After the test, basic insulation shall not be exposed and the electric strength test of 16.3 is
carried out between the conductors connected together and the saline solution.
21.104 Current-carrying hoses shall be resistant to flexing.
Compliance is checked by the following test.
The end of the hose intended to be connected to the motorized cleaning head is attached to
the pivoting arm of the test equipment shown in Figure 103. The distance between the pivot
axis of the arm and the point where the hose enters the rigid part is 300 mm ± 5 mm. The arm
can be raised from the horizontal position by an angle of 40° ± 1°. A mass of 5 kg is
suspended from the other end of the hose or from a convenient point along the hose so that
when the arm is in the horizontal position the mass is supported and there is no tension on
the hose.
NOTE 1 It may be necessary to reposition the mass during the test.
The mass slides against an inclined plate so that the maximum deflection of the hose is 3°.
The arm is raised and lowered by means of a crank that rotates at a speed of 10 ± 1 r/min.

SIST EN 60335-2-69:2003/A1:2005
60335-2-69 Amend. 1  IEC:2004(E) – 9 –
The test is carried out for 2 500 revolutions of the crank after which the fixed end of the hose
is turned through 90° and the test continued for a further 2 500 revolutions. The test is
repeated in each of the other two 90° positions.
NOTE 2 If the hose ruptures before 10 000 revolutions of the crank, the flexing is terminated.
After the test, the hose shall withstand the electric strength test of 16.3.
21.105 Current-carrying hoses shall be resistant to torsion.
Compliance is checked by the following test.
One end of the hose is held in a horizontal position with the remainder of the hose freely
suspended. The free end is rotated in cycles, each cycle consisting of five turns in one
direction and five turns in the opposite direction, at a rate of 10 turns per minute.
The test is carried out for 2 000 cycles.
After the test, the hose shall withstand the electric strength test of 16.3 and shall not be
damaged to such an extent that compliance with this standard is impaired.
21.106 Current-carrying hoses shall be resistant to cold conditions.
Compliance is checked by the following test.
A 600 mm length of hose is bent as shown in Figure 104 and the ends are tied together over a
length of 25 mm. The hose is then placed for 2 h in a cabinet having a temperature of
−15 °C ± 2 °C. Immediately after the hose is removed from the cabinet it is flexed three times,
as shown in Figure 104, at a rate of one flexing per second.
The test is carried out three times.
There shall be no cracks or breaks in the hose and it shall withstand the electric strength test
of 16.3.
NOTE Any discoloration is neglected.
24 Components
Add the following subclause:
24.2 Addition:
For appliances worn on the body in normal use, a remote switching device may be located at
