IEC 60335-2-2 Vacuum Cleaner Current-Carrying Hoses Abrasion Resistance Test Equipment
Product Overview:
This current-carrying hoses abrasion resistance test equipment meets the standard of IEC60335-2-2, clause 21.102 figure 101. Suitable for verifying the vacuum cleaners or water-suction cleaning appliances's current-carrying hoses shall be resistant to abrasion.
Test Procesures (Extracted from IEC 60335-2-2 clause 21.102):
One end of the hose is attached to the connecting rod of the crank mechanism shown in Figure 101. The crank rotates at 30 revolutions per minute resulting in the end of the hose moving horizontally backwards and forwards over a distance of 300mm.
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.
Test 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 clause 16.3 is carried out between the conductors connected together and the saline solution.
