0 S: N2 L' L7 s* D) z/ r$ JAs it is very difficult to evaluate "wear impairing their further use" without testing, a non-subjective evaluation criterion is needed.

After the temperature rise and the repetition of the test according to clause 14.2, both with positive results, it can be assumed that wear impairing further use is not present.
