Apparatus for Testing Cord Retention | MT-CR901;

Test Procedure

The specimen is placed in the test apparatus so that the axis of the flexible cable is vertical where it enters the specimen
The flexible cable is then subjected 100 times to a pull of
– 50 N if the rated current is 2,5 A,
– 60 N if the rated current is above 2,5 A, but not more than 16 A and the rated voltage is up to and including 250 V,
– 80 N if the rated current is above 2,5 A, but not more than 16 A and the rated voltage is above 250 V,
– 100 N if the rated current greater than 16 A.
The pulls are applied practically without jerks each time for 1 s.

Requirements

After the tests, the flexible cable shall not have been displaced by more than 2 mm. For rewirable accessories, the end of the conductors shall not have moved noticeably in the terminals; for non-rewirable accessories, there shall be no break in the electrical connections.
