Compliance is checked by the following tests. The motorized cleaning head is subjected to an impact test as describ
34、ed 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
35、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

While the hose is still immersed, a volta
39、ge 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 19.7 Addition: Motorized cleaning heads are tested with the rotating
40、brush or similar device locked for 30 s. 20? ? Stability and mechanical hazards Add the following subclauses: 20.1 Addition: NOTE 101 Motorized cleaning heads are not subjected to this test. 20.102? Shaft ends and similar rotating parts shall be protected if they protrude by more than a quarter of t
41、heir 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 inju
42、ry to the feet of the operator is prevented. Compliance is checked by inspection, by measurement and by manual test. 21? ? Mechanical strength Replace the modification by the following: 21.1Modification: The impact value is increased to 1,0 J. Add the following subclauses: 21.102 Current-carrying ho
43、ses 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 t
44、o 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 carrie
45、d 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 3
46、0 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
47、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 sh
48、all 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
49、 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.
