The liquid container is filled with water to half the level indicated in the instructions. The appliance is placed on a support inclined at an angle of 100 to the horizontal. A force of 180 N is applied to the top of the appliance in the most unfavourable horizontal direction, lithe appliance overturns, it is considered to be liable to be overturned in normal use.
Appliances with type X attachment, except those having a specially prepared cord, are fitted with the lightest permissible type of flexible cord of the smallest cross-sectional area specified in Table 13.
Appliances incorporating an appliance inlet are tested with or without an appropriate connector in position, whichever is more unfavourable.
Liquid containers that are filled by hand are completely filled with water containing approximately 1 % NaCl, and a further quantity, equal to 15 % of the capacity of the container or 0,25 I, whichever is the greater, is poured in steadily over a period of 1 mm.
Containers of hand-held appliances and other appliances liable to be overturned in normal use are completely filled, the cover being closed. The appliance is then overturned and left in that position for 5 mm, unless it returns automatically to its normal position of use.
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 NaG! and 1 ml of a solution of
28 % by mass of dodecyl sodium sulphate in each 8 I of water. The solution is to be stored in
a cool atmosphere and used within seven days of its preparation.
The appliance is operated until its liquid container is completely full and for a further 5 mm.
NOTE 101 The chemical designation of dodecyl sodium sulphate is C12H25NaSO4.
After each of these tests, the appliance shall withstand the electric strength test of 16.3.
Inspection shall show that there is no trace of liquid on insulation that could result in a reduction of clearances or creepage distances below the values specified in Clause 29.
15.101 Motorized cleaning heads of water-suction cleaning appliances shall be resistant to liquids that may come into contact with them.
Compliance is checked by the following 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 test Free fall — Procedure 1 of IEC 60068-2-3 1. 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, the water containing approximately 1 % Na Cl.AS NZS 60335.2.2 pdf download.
