Installations and equipment must regularly be subjected to an electrical safety test.

The Inspections methods are described in the NEN 3140 standard. This standard focuses on safety (e.g. earthing) and limiting the fire hazard (due to poor contacts).
Experimental objects must also satisfy the NEN 3140 standard.
Wall sockets and extension leads must be checked regularly. The same applies to tools.
