Example 15: Tested! Completely turned.

The requirement on cables for the energy supply chain with regard to its "torsion resistance" is not new, but is clearly defined only very rarely. So how would you evaluate a statement like "This cable is torsion-resistant up to ±180°!"? That's why it is all the more important to be able to deliver comparable and conclusive test results.

Due to this requirement, the "torsion test bench" was developed according to the igus® standard. Here diverse cable types are twisted to a specified cable length of 1 meter, which also conforms to the distance of the fixed points. The torsion angle can be freely selected and is fixed according to the requirement on the specimen, but the test standard is ±180°.

After a specified number of double strokes or a negative electrical and/or mechanical test result, the relevant specimen is taken apart, thereby precisely determining the type and position of possible damages.

By means of this igus® standard test, the first Chainflex® CF ROBOT types were developed up to series production.
