What is the DGUV V3 test?

Most entrepreneurs are familiar with the term DGUV V3 inspection or formerly BGV A3. But what exactly is it about? And what actually has to be tested? Do the test reports actually have to be documented?

The DGUV V3 is a VDE test that ensures that all electrical equipment is working properly and provide protection against electric shock, the results of which must be documented.

The DGUV V3 stands for …

The DGUV stands for the German statutory accident insurance. This is a compulsory insurance, which all employers in Germany have to bear. This serves to ensure the protection of all employees. With the underlying regulation, the DGUV wants to prevent as many work accidents as possible. Which is why there are basic principles that all entrepreneurs in Germany must follow.

One of these regulations is the Rule 3.

This means the DGUV V3

Regulation 3 contains all regulations concerning the “testing of portable electrical equipment and devices“. This includes, for example, the following devices:

  • All household appliances such as toasters, blenders, coffee makers, refrigerators etc.
  • Power tools
  • Notebooks, computers
  • Screens
  • Printer
  • Extension cords and multiple sockets
  • Chargers
  • Etc.

Which test deadlines must be observed?

If a new device, equipment or system is purchased, or if a modification has been made, it must be tested for functionality and for safety against electric shock before it is put into operation for the first time. The device, equipment or system may only be put into operation if these tests are faultless.

The inspection intervals for the repeat inspections then depend on the following factors:

  • Error rate, i.e. how often did abnormalities or deficiencies occur during the tests.
  • Place of use, e.g. office, construction sites, kitchens, building cleaning, laboratories, schools, etc.
  • Frequency of use, i.e. daily or rather every few months

Based on these factors, a hazard assessment is made and the inspection intervals are selected in relation to this hazard assessment. The DGUV V3 recommends a general inspection period of 6 months, i.e. the devices should be inspected every 6 months. However, this is only a guideline, the actual testing interval is determined based on the risk assessment. If the error rate is below or above 2%, the inspection interval can be extended or shortened accordingly.

Here are some examples:

  • For power tools in the craft sector, which are used almost daily, the DGUV V3 recommends a period of 3 months. Due to the high stresses, these devices are more often prone to conspicuities and defects.
  • For electrical equipment in kitchens for communal catering, the DGUV recommends an inspection period of 6 months.
  • Electrical equipment that is used, for example, in building cleaning, laboratories and schools is test period of 12 months is recommended..
  • In care facilities and office operations, a testing period of 24 months isprovided because the portable equipment in these areas is often moved little to not at all.
