71 age 72 of 186 Test Report Ref. No.: VDE ET In item a) add the following notes: Considered NOTE 1: Any voltage below maximum systems voltage can be used but the test should start at zero voltage because it may happen that maximum systems voltage is not stated or unknown. NOTE 2: When increasing the test voltage partial discharges may appear periodically. In that case, the inception voltage is the test voltage at which permanent discharges occur for a duration of at least 60 s. In item b) add the following notes: Considered NOTE 3: Because partial discharges can disappear periodically, partial discharges at extinction voltage should stay below 1 pc for minimum of 60 s In item e) replace Uoc by Voc Considered

Both backsheets have identical chemical, electrical and physical properties. Due to engineering decision only the V-BS MGEW-SbR backsheet was tested. The testing on the black patterned back sheet BS V-BS MGEW-SbR was omitted since it was considered less critical all black version.

114 age 148 of 186 Test Report Ref. No.: VDE ET2-1 Summary of testing: Tests performed (name of test and test clause): Retest clause e) Backsheet(V-BS MGEW-SbR, V-BS MGEW-SbR) addition, Black string connector (Black , Sn-b, 40 μm) addition. Both backsheets have identical chemical, electrical and physical properties. Due to engineering decision only the V-BS MGEW- SbR backsheet was tested. The testing on the black patterned back sheet BS V-BS MGEW-SbR was omitted since it was considered less critical all black version.
