GMC-I Messtechnik GmbH 57
19.3 Periodic Testing per DGUV Regulations 3 (formerly BGV A3)
– Limit Values for Electrical Systems and Operating Equip-
ment
Limit Values per DIN VDE 0701-0702
Maximum Allowable Limit Values for Protective Conductor
Resistance for Connector Cables with Lengths of up to 5 m
1
This value may not exceed 1  for permanently connected data processing sys-
tems (DIN VDE 0701-0702).
2
Total protective conductor resistance: max. 1 
Minimum Allowable Limit Values for Insulation Resistance
* With activated heating elements (where heating power > 3.5 kW and R
INS
< 0.3
M: leakage current measurement is required)
Maximum Permissible Limit Values for Leakage Current in mA
* For devices with heating power of greater than 3.5 kW
Note 1: Devices which are not equipped with accessible parts that are
connected to the protective conductor, and which comply with re-
quirements for housing leakage current and, if applicable, patient
leakage current, e.g. computer equipment with shielded power
pack
Note 2: Permanently connected devices with protective conductor
Note 3: Portable X-ray devices with mineral insulation
