50Hz Electrical Appliance Tester , Power Cord Flexibility Preformance Tester 3 Station , 6 Station

IEC60335-1 Electrical Appliance Tester Power Cord Flexibility Preformance Tester Of 3station,6 Station

Standard

EC60335-1 2005 clause 23.3 and 25.14

Application

It is used to test the bending resistanceperformance of power lead connectors of small household appliances (such as coffee makers/irons, etc.), lamps, etc.It is judged by whether the current is connected.

Test sample

coffee makers/irons, lamps.

Function

The number of trials can be preset, and when the number of time is reached,it can shutdowns automaticly. The equipment can be equipped with a load to enable testing of small household appliances with different rated currents.

Technical Parameters :

standard description :

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 conductor, 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 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 Iargest allowed by the construction, the rate of flexing being 30 per minute. The

number of flexing is

--10 000. for conductors flexed during normal use;

100, for conductors flexed during user maintenance.

The appliance shall not be damaged to the extent that compliance with this standard

impaired and it shall be fit for further use. In particular, the wiring and its connections shall

The appliance shall not be damaged to the extent that compliance with this standart is imparred 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.
