How to interpret this certification
Each certificate covers specific products and uses. These details explain what is covered.

DNV type approval is proved by the certificate and its Approval Finder record. A DNV logo on a brochure does not show the approved model, application, environmental category or expiry.
Fire safety products often covered

- Shipboard alarm and control equipment
- Fixed fire-extinguishing systems
- Fire-resistant construction products
- Offshore safety equipment
Points to check before you buy
- 01
DNV GL certificates may remain in historical records; current certificates use the DNV name. Verify either through Approval Finder.
- 02
Match the vessel, class notation, environmental category, software version and certificate conditions.
- 03
MED certificates issued by DNV are separate from DNV class type approval.
Before you buy
What to check before relying on this certification
Certification is normally limited to a named model, configuration, standard and use. These checks turn a marketing claim into a procurement record.
- 01
Confirm the vessel's flag, class society, notation and the equipment category required by the approved design.
- 02
Match the exact model, software version, environmental category and installation limitations to the certificate.
- 03
Distinguish EU Marine Equipment Directive wheelmarking from a class-society type approval.
- 04
Check certificate validity, production-surveillance status and whether flag or class acceptance is still required.
