Testing Devices per DIN VDE 0701, Part 1: 2000
The limit values specified in the following chapters correspond to current revision levels of
official standards at the time of going to print. Please note that normative legislation is contin-
uously updated to meet the safety requirements necessitated by changing market situations,
and that the listed limit values are thus subject to change. Please contact our update service
department in order to adapt test instruments to new standards.
5.1
General
According to DIN VDE 0701, part 1, edition 2000, repaired or modified electrical devices
must provide users with the same protection against electrical energy as is offered by new
devices. The following tests must be performed to this end, in the order indicated:
1 Visual inspection
2 Protective conductor resistance
3 Insulating characteristics:
if technically sensible, i.e. if the DUT does not include any all-pole,
electrically actuated switches:
– Insulation resistance followed by protective conductor current or equivalent leakage
current
– Other: leakage current during operation (protective conductor current and contact
current), safety extra-low voltage (only at connecting points for safety extra-low
voltage generated within the device under test)
4 Function test
5 Labelling inspection
6 Documentation
Note!
+
Measurement of residual current is only possible with the METRATESTER
â
5/5-F.
Changes to DIN VDE 0701-1: 1993
•
The standard has been completely revised as regards both layout and technical aspects.
•
Test procedures have been adopted for devices whose insulation characteristics cannot
be fully evaluated before initial start-up.
•
The limit values for protective conductor resistance and insulation testing have been
re-specified.
•
Device-specific supplements in parts 10 through 13 and 260 have been integrated by
means of device-specific appendices E through H in part 1.
•
In order to substantiate the insulation characteristics of the device under test,
measure-
ment of leakage current with line voltage
has been additionally prescribed. This represents a
stiffening of previous stipulations, which takes the ever increasing percentage of devices
with capacitive circuitry into consideration.
•
Protective conductor resistance values
have been aligned to DIN VDE 0702.
The limit value is:
–
0.3
W
(for up to 5 meters) plus 0.1
W
for each additional 7.5 meters.
•
The protective conductor for safety class I hand-held electric tools can now be tested
with minimal test currents as well.
