8. Conducting tests in accordance with
DIN VDE 0701-0702 Definition of standards
The sequence of tests is specified in the standard.
8.1. Visual inspection
The test objects are inspected for externally visible defects.
8.2. Measuring the protective conductor resistance
(for devices of protection class I)
The limit value is:
≤≤≤≤≤ 0.2 Ω Ω
Ω Ω
Ω for devices with connecting cables up to 5 m,
plus 0.1
Ω Ω
Ω Ω
Ω
for every extra 7.5 m, up to a maximum of
1.0

Also applies to touchable conductive parts of test objects
in protection class I that are not connected to the protective
conductor.
2)
If the required insulation resistance is not achieved in the
case of test objects in protection class I with heating
elements with a total capacity
≥
3.5 kW, the test object is
nevertheless rated as faultless if the protective conductor
current does not exceed the limit values.
