Inspection and Monitoring

Certification with the VDE mark is required when the production of the approved products is monitored. The aim of monitoring the certified products is to ensure constant quality and condition – analogous to the initial authorization.

The VDE Institute conducts – either upon request or as a special inspection measure as part of conformity monitoring – additional inspections and product control tests.
