IEC 60335-2-2 Vacuum Cleaner Current-Carrying Hoses Flexing Resistance Test Equipment

Product Overview:

This current-carrying hoses flexing resistance test equipment meets the standard of IEC60335-2-2, clause 21.103 figure 102. Suitable for verifying the vacuum cleaners or water-suction cleaning appliances's current-carrying hoses shall be resistant to flexing.

Test Procesures (Extracted from IEC 60335-2-2 clause 21.103):

The end of the hose intended to be connected to the motorized cleaning head is attached to the pivoting arm of the test equipment shown in Figure 102. 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 supported and there is no tension on the hose.

If necessary the mass may be repositioned during the test.

The mass slides against an inclined plate so that the maximum deflection of the hose is 3 °. The arm is raised and lowered by means of a crank that rotates at a speed of 10 r/min ±1 r/min.

The test is carried for 2500 revolutions of the crank after which the fixed end of the hose is turned through 90° and the test continued for a further 2500 revolutions. The test is repeated in each of the other two 90° positions. If the hose ruptures befoer 10000 revolutions of the crank, the flexing is terminated.
