) Measurements were executed on studs size M8/7 or M8/10 and grating clip size 3-25 37/41, 28/32 and 25/30
respectively and averaged over tree test samples.
Test setup:
The test setup was in the spirit of IEC / EN 61537, Section 11.1 and the measurements were con-
ducted with the 4-wire resistance measurement method.
