Contents of BGV A3: The test as per BGV A3 is divided into a visual and a metrological test.

Visual inspection:

- Protective conductors (protection class I )

- Insulating parts

- Housing

- Connecting cables

- Typeplate

- Machine-specifi c components

Metrological test:

- Short-circuit test

- Protective conductor resistance (RSL)

- Equivalent leakage current (IEA)

- Insulation resistance (Riso)

- Functional test

Attention!

 If one of the above-specifi ed criteria cannot be fulfi lled, then the test is

 considered a failure.

If the customer refuses the necessary repair, he must be informed in writing to this eff ect. Clear reference must 

be made to the fact that safe operation of the system cannot be assured. This must be counter-signed by the 

operating company. 

You must fulfi l this obligation as you, as an expert, will be required to produce evidence in the event of dama-

ge.

FIVE SAFETY RULES 

The Five Safety Rules are more than just rules. They are the precondition for working on electrical systems and appliances. Please 

take these rules seriously - they are essential for your safety. 

Isolation 

Isolation means all-pole disconnection of a system from live parts. 

All live cables must be disconnected at all poles at the place of work before starting work. This can be done by means of main 

switches, expert removal of fuses, disconnection of plug connectors etc. 

Protecting against restarting 

In order to prevent inadvertent restarting of a system on which work is being carried out, restarting must be prevented reliably 

and safely. For example the unscrewed fuse elements can be replaced with lockable disabling elements or circuit-breakers can be 

masked with adhesive fi lm. A "Please do not switch on - work in progress" sign can also be affi  xed. For appliances which are con-

nected to the network by a plug connector, it is suffi  cient to store the unplugged connector on the machine in such a way that it 

cannot be mixed up with another connector. In addition, the connector must always be kept in the worker's immediate vicinity. 

Verifi cation of safe isolation from the supply 

Verifi cation of safe isolation from the supply in low-voltage networks, i.e. systems with operating voltages below 1000 V, must 

only be carried out using devices or equipment suitable for this purpose. A two-pole measuring instrument must be used. The 

voltage detectors used must comply with the respective rated voltage and must be tested before and after verifi cation of safe 

isolation from the supply. I.e. the function of the detectors must be tested on a reliable live source.
