Conducting tests:
General information on DIN VDE 0701-0702:2008-06

Up to June 2008, appliances able to be disconnected from the system via
plug connections were to be tested according to DIN VDE 0701 after any
maintenance, repair or modification measures. Repeated tests were to be
performed according to DIN VDE 0702.

The VDE 0702 standard, applicable since June 2004, states that electrical
devices which are normally connected via a plug connection but are
actually permanently connected must be tested according to this standard.
The decisive factors for the testing / inspection interval are how the
movable electrical device is used, how it is affected by the environment
and how it is moved. The main consideration is always the estimation of
possible danger to the user in the case of a defect.
Devices belonging to a stationary system are to be tested together with the
associated system according to DIN VDE 0105-100. However, it is also
possible to separate devices from a system which they are permanently
connected to and test them according to the VDE 0702 „Periodic
inspections“.

Point 4 of the DIN VDE 0701-0702 standard „Inspection after repair,
modification of electrical appliances - Periodic inspection on electrical
appliances - General requirements for electrical safety“, applicable since
June 2008, clearly states that:
„A device that cannot be moved without auxiliary equipment and which is
connected to an electrical system via a permanent, protected cable and
which is not held in the hand when used correctly may be subjected to
periodic inspection according to Point 5 (of DIN VDE 0701-702) or according
to DIN VDE 0105-100 depending on the decision of the electrical professional
responsible“.
In contrast to tests after repair or modification, periodic inspections usually
take place on site. The device is to be disconnected from the „mains“, i.e.
the electrical system, before testing. This is the only way of performing a
full test on this type of device.

VDE 0701-0702 defines the sequence of tests as follows:
–

Visual inspection

–

Protective conductor test

–

Insulation resistance measurement
(where possible, not with IT devices)

–

Protective conductor current

–

Touch current

–

Evidence of safe disconnection from the power supply circuit
(SELV and PELV)

–

Evidence of the effectiveness of other safety devices

–

Final inspection of the inscriptions

–

Function test

If the device to be tested cannot be disconnected from the electrical system,
then proceed as follows:
–

Visual inspection

–

Measure the protective conductor resistances for protective class I
devices and

–

Measure the touch current on touchable, conductive parts of protective
class II devices and touchable, conductive parts of protective class I
devices that are not connected to the protective conductor.

If the memory card or the internal memory needs to be fully erased, then
press the

[delete] function button

(Fig. 12) in the configuration menu

(Page 2) and confirm the confirmation prompt.

Caution! The [delete] function permanently deletes all existing data
from the internal memory or the memory card.

Use the

[internal copy –> MMC/SD] function button

(Fig. 12) to copy

the internal memory to the memory card.

To read out the stored measurement results and create a test log - see the
operating manual of the PC software supplied with the tester.
