Robustness of terminations testing machine for solar panel test with IEC61215-2:2016 testing standard

Robustness of terminations testing machine for solar panel test with IEC61215-2:2016 testing standard 

Testing Standard 

It's conform IEC61215-2:2016 testing standard 

Purpose

It’s to determine that the terminations, the attachment of the terminations, and the attachment of the cables to the body of the module will withstand stresses that are likely to be applied during normal assembly or handling operations, test in 4.14.2 (MQT14.1) and test in 4.14.3 (MQT 14.2) are to be performed .

Retention of junction box on mounting surface

Apparatus:

Applying a force of 40N to the centre of the test object. Prevent torque from being applied to the junction box

Attaching the means for applying the force to the junction box shall not impair its functions

Procedure

1. A force of 40N shall be gradually applied for 10±1s in each direction parallel to the mounting surface parallel to the module edge, in steps of 90°

2. A force of 40N shall be gradually applied for 10±1s without jerks , in a direction perpendicular to the mounting surface

3. The pull force should be applied at the centre point of the box

Cord anchorage pull testing

Testing procedure

1. The unloaded cable shall be marked so that any displacement relative to the gland can be easily detected

2. The cable is pulled for duration of 1s, 50times, without jerks in the direction of the axis with the relevant force

3. At the end of the pull test, remove the force from the test mandrel, then measure the displacement of the cable at the outlet of the junction box

Cord Anchorage torque testing

1. After the pull test the specimen shall be mounted in the test apparatus for torque test

2. The unloaded cable shall be marked so that any torsion relative to the gland can be easily detected, and then a  

torque shall be applied for 1min

3. During the test, the twist or torsion inside the cable gland or other cord anchorage shall not exceed 45°, the cable shall be held in position by the cord anchorage
