The machine is placed on a support inclined at an angle of 10° to the horizontal, the liquid container being filled to half the level indicated in the instructions. A machine is considered to be unstable if it overturns when a force of 180 N is applied to the top of the machine in the most unfavourable horizontal direction. Machines 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 11. Hand-guided machines and hand-held appliances and machines that are unstable are then, with the containers completely filled for the float tank, if any, and with the most conductive detergent for the detergent tank, if any, and with the cover lid in place, tilted 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. Liquid containers that are filled by hand are completely flled with a saline solution of water containing approximately 1 % NaCI and 0,6 % rinsing agent and a further quantity, equal to 15 % of the capacity of the container or 0,25 , whichever is the greater, is poured in steadily over a period of 1 min.
The motorized cleaning head is then subjected to the test described in 14.2.4 of IEC 60529:199, using the test solution. The motorized cleaning head shall be operated in a flat-bottomed vessel filled with a saline solution of water containing approximately 1 % NaCI so that a depth of 3,0 mm of water is maintained. The vessel is to be a size such that the motorized cleaning head moves about freely; and is to be operated with or without connection to the high pressure cleaner for 15 min whichever applicable. 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 clearances or creepage distances below the values specified in Clause 29. Current-carrying hoses, except for their electrical connections, are immersed for 1 h in a saline solution of water containing approximately 1 % NaCI, at a temperature of 20 °C土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.AS NZS 60335.2.79 pdf download.
