IEC60335-2-2 Current-Carrying Hoses Flexing Resistance Tester 10r/min Flexing Speed

Foreword: In practice, some current carrying hoses need to adapt to various environments for continuous expansion and bending. The current carrying hose with poor quality is easy to break after being bent for a certain number of times. Therefore, before the hose leaves the factory, it is very important to test the bending resistance.
This tester has the characteristics of simple structure, convenient detection and good detection effect. It can effectively reflect the bending resistance of current carrying hose and effectively ensure the ex factory quality of products. Electrical Appliance Tester

Standard: This device meets the standard of IEC60335-2-2, clause 21.103 figure 102.

Application: Suitable for the Current-carrying hoses flexing resistance tester.

Test sample: Vacuum cleaner hoses, water suction type cleaning apparatus tube, washing machine water pipe. Electrical Appliance Tester

Feature: 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 300mm±5mm. 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.

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±1 revolutions per minute. Electrical Appliance Tester

The test is carried out 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.
