Appliances shall be constructed so that spillage of liquid in normal use does not affect their electrical insulation even if an inlet valve fails to close.
Compliance is checked by the following test.
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 intended to be filled with water by the user are completely filled with water containing approximately 1 % NaG!. A further quantity of this solution equal to 15 % of the capacity of the appliance or 0,25 I, whichever is greater, is poured in steadily over a period of 1 mm.
Other appliances are operated until the maximum water level is reached, and 5 g of the detergent specified in Annex AA is added for each litre of water in the appliance. Each inlet valve is held open and the filling is continued for 15 mm after first evidence of overflow or until the in flow is automatically stopped by other means. The appropriate tests being applied one at a time to each inlet valve.
For appliances that are loaded from the front, the door is then opened if this can be achieved manually and without damage to the door interlock system.
For all appliances, 0,5 I of a solution comprising water containing approximately 1 % NaCI and 0,6 % of rinsing agent, is rapidly poured over the top of the appliance so that the spillage solution flows over the surfaces of the appliance that incorporate controls, the controls being placed in the on position. The controls are then operated through their working range, this operation being repeated after a period of 5 mm.
The appliance is operated under the conditions specified in Clause 11 but at rated voltage for one complete cycle with the programme that results in the longest period of operation. A quantity of detergent necessary to cause foaming is added. The composition of the detergent is specified in Annex AA.
For appliances incorporating a detergent dispenser, the solution is added manually at the point in the cycle when it would normally be dispensed automatically. For other appliances, the solution is added before starting the cycle.AS NZS 60335.2.7  pdf download.
