Flexible Cable Torque Testing Machine For Cord Anchorages IEC60884-1
Product details:
This tester conforms to IEC60884-1 clause 23.2.After testing cord retention. the flexible cable is subjected for 1 min to a torque as specified in the following table:
Torque test values for cord anchorages:
| Rating of plug or portable socket-outlet | Flexible cable (number of cores × nominal cross-sectional area in mm2) |
|
| 2*0.5 | 2*0.75 | 3*0.5 | 3*0.75 | (2 or more)*1 |
| Up to and including | 0,10Nm | 0.15Nm | 0.15Nm | 0.25Nm | 0.25Nm |
| 16A and above 250V | - | - | - | - | 0.35Nm |
| Above 16A | - | - | - | - | 0.425Nm |
The flexible cable is then subjected 100 times to a pull of:
After the test, 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. For measurements of the longitudinal displacement, a mark is made on the flexible cable at a distance of approximately 20 mm from the end of the specimen or the flexible cable guard, before it is subjected to the pull.
For non-rewirable accessories, If there is no definitive end to the specimen or the flexible cable guard, an additional mark is made on the body of the specimen.
The displacement of the mark on the flexible cable in relation to the specimen or flexible cable guard is measured while the flexible cable is subjected to the pull.
The pulls are applied practically without jerks each time for 1 s.
Care shall be taken to exert the same pull on all parts (core, insulation and sheath) of the flexible cable simultaneously.
Weight: 2N/3N/5N/7N/8.5N*1
Conforms to standard: IEC60884 clause 23.2 (table 18), VDE0620 clause 23.2 (table18)
