Figure 21 Plug Cord 999999 Flexibility Test Apparatus

IEC 60884-1 Figure 21 Plug Cord Flexibility Test Apparatus With 6 Station Button Control

Standard:

IEC 60884-1 'Plugs and socket-outlets for household and similar purposes – Part 1: General requirements' clause 23.4, figure 21

Standard description:

Non-rewirable plugs and non-rewirable portable socket-outlets shall be designed in such a way that the flexible cable is protected against excessive bending where it enters the accessory.

Guards provided for this purpose shall be of insulating material and shall be fixed in a reliable manner.

Compliance is checked by inspection and by a flexing test made by means of an apparatus as shown in figure 21.

The test is made on new specimens.

The specimen is fixed to the oscillating member of the apparatus so that, when it is at the middle of its travel, the axis of the flexible cable, where it enters the specimen, is vertical and passes through the axis of oscillation.

Specimens with flat cords are mounted so that the major axis of the section is parallel to the axis of oscillation.

The accessory shall be fixed in the test apparatus in the following way:

– plugs: by the pins;

– portable socket-outlets: at a distance of 4 mm to 5 mm in the direction of the flexible cable, from the engagement face; a test plug having the maximum dimensions shall be inserted in the portable socket-outlet during the test.

The accessory is, by variation of the distance between the fixing part of the oscillating member and the axis of oscillation, positioned so that the flexible cable makes the minimum lateral movement when the oscillating member of the test apparatus is moved over its full travel.

The flexible cable is loaded with a mass such that the force applied is

– 20 N for accessories with flexible cables having a nominal cross-sectional area exceeding 0,75 mm ² ;

– 10 N for other accessories.

A current equal to the rated current of the accessory or the following current, whichever is the lower, is passed through the conductors:

– 16 A for accessories with flexible cables having a nominal cross-sectional area larger than 0,75 mm²;

– 10 A for accessories with flexible cables having a nominal cross-sectional area of 0,75 mm² ;

– 2,5 A for accessories with flexible cables having a nominal cross-sectional area less than 0,75 mm² .

The voltage between the conductors is equal to the rated voltage of the specimen.

The oscillating member is moved through an angle of 90° (45° on either side of the vertical), the number of flexings being 10 000 and the rate of flexing 60/min.

Specimens with circular section flexible cables are turned through 90° in the oscillating member after 5 000 flexings; specimens with flat flexible cables are only bent in a direction perpendicular to the plane containing the axes of the conductors.

During the flexing test, there shall be

– no interruption of the current,

– no short circuit between conductors.

After the test, the guard, if any, shall not have separated from the body and the insulation of the flexible cable shall show no sign of abrasion or wear; broken strands of the conductors shall not have pierced the insulation so far as to become accessible.

Application:

This device is used for test the flexing properties of non-rewirable plugs (terminals) and non-rewirable portable socket-outlets, check the fatigue strength of the power cable and jacket.

Test sample:

Non-rewirable plugs and non-rewirable portable socket-outlets

Feature:

The speed reducing motor controls the crank sliding block structure to do the reciprocating motion, the left and right flexing angles are adjusted by manual scale, and angle automatic adjustment touch screen model can be customized.

Tester will automatic shutdown when preset test times completed.
