NEK 405-3-2 Electrical Control Road Traffic Systems is a substandard in the NEK 405 series, with methodology and certification scheme for the road sector for third-party assessment of deliveries of electrical installations and electrical equipment to ensure that these comply with regulatory and contractual requirements.

The standard shall also form the basis for third-party assessment of fulfilment of operation and maintenance contracts and general control of assignments. The standard initially covers the road sector, but is based on a model that may be relevant for the entire transport sector and for critical infrastructure in general.

Typical clients are road owners such as the Norwegian Public Roads Administration, Nye Veier, Counties and municipalities.

In December 2023, the competency requirements were increased in order to take the exam.

The course provides a good competence base for conducting certification exams. If you wish to take the exam, you can follow the link.



The exam can be conducted digitally on for example teams, after the course. This is agreed with the person you are going to certify with (DNV or NEMKO).
