IEC60335-1 Touch Screen Supply Cord Flexing Test Apparatus Electrical Appliance Tester

IEC60335-1 Touch Screen Supply Cord Flexing Test Apparatus Electrical Appliance Tester
 

Standard description(IEC60335-1 clause 23.3):

Different parts of an appliance that can move relative to each other in normal use or during user maintenance shall not cause undue stress to electrical connections and internal conductors, including those providing earthing continuity. Flexible metallic tubes shall not cause damage to the insulation of the conductors contained within them. Open-coil springs shall not be used to protect the wiring. If a coiled spring, the turns of which touch one another, is used for this purpose, there shall be an adequate insulating lining, such as the sheath of a flexible cord complying with IEC 60227, IEC 60245 or IEC 62821 , in addition to the insulation of the conductors.
Compliance is checked by inspection and by the following test.
If flexing occurs in normal use, the appliance is placed in the normal position of use and is supplied at rated voltage and operated under normal operation.
The movable part is moved backwards and forwards, so that the conductor is flexed through the largest angle allowed by the construction, the rate of flexing being 30 per minute. The number of flexings is:
– 10 000, for conductors flexed during normal use;
– 100, for conductors flexed during user maintenance.
NOTE A flexing is one movement, either backwards or forwards.
The appliance shall not be damaged to the extent that compliance with this standard is impaired and it shall be fit for further use. In particular, the wiring and its connections shall withstand the electric strength test of 16.3, the test voltage being reduced to 1 000 V and applied between live parts and accessible metal parts only. In addition, not more than 10 % of the strands of any conductor of the internal wiring between the main part of the appliance and the movable part shall be broken. However, if the wiring supplies circuits that consume no more than 15 W, then no more than 30 % of the strands shall be broken.

Product Introduction:

The supply cord flexibility performance tester is special designed and manufactured according to clause 23.3 and 25.14 of IEC60335-1, IEC60745-1 clause 24.12 figure 9,GB4706-1, IEC60335-2-14, GB4706-30 and etc., it is used to check the power cord flexing (bending) resistance performance of the small household appliances (such as Coffee pot / electric iron), also applicable for power cord flexing endurance tester of plugs and sockets.
 

The test device adopts to PLC electrical control, 7-inch color touch screen intelligent operation system; servo motor controlling the test angle, high precision digital instrument, high performance digital frequency conversion, precise speed regulation, six number memory timer, multifunctional combined clamps, center gauge of rotation, bending angle adjustable, 4kw output power. Test times (maximum of 999999 times), test speed, and test angles can be preset; it has electric current detection function. This device can meet the test requirements of most of small household electrical appliances, the applicable range is widely.
