Use of certification marks

Certification by DNV GL

Certification by DNV GL to international or national standards demonstrates your commitment to continual improvement and sustainable business performance. This achievement is more than a ticket-to-trade. It is something to be proud of, and communicating your commitment in the market can help build stakeholder trust and brand confidence.

Companies achieving DNV GL certification are entitled to use DNV GLs Certification Mark. The Certification Mark is designed specifically for the purpose of visually and clearly communicating your commitment to the market. The certification mark can be used in various ways, from marketing material to company buildings.

Typical example of the look and feel for DNV GLs Certification Mark used for management system certification:


There are certain limitations for use of the Certification Mark for management system certification standards. One important condition is to avoid using the mark in a way that could indicate that the product or service provided is certified. The above mark is therefore not allowed to be used on

  • Product and product packaging (including accompanying information)
  • Certificates, statements of conformity, reports etc. as an output from services provided by the certificate holder (e.g. testing and calibration activities, inspections, assessments etc.)

DNV GL has established guidelines and rules for use of its certification marks, which is distributed to certified clients. In addition to providing guidance for the correct use of the marks, it also provides useful examples on where it can be displayed etc.

Use of the DNV GL inscription – an alternative to the mark

An alternative to the use of the Certification Mark is to use the Inscription. The Inscription can in general be applied where the Certification Mark can be applied. However, the Inscription is additionally allowed to be used where the Mark has its restrictions as listed above, except on products.

Conditions and guidance for use of the Inscription is covered as part of the DNV GL guidance document here.

Typical example of the inscription used for management system certification:
