ENAC presents the new accreditation mark

The accreditation mark is the means by which the market identifies both the accredited entities and the certificates and reports covered by the ENAC accreditation and which, therefore, have the reliability provided by the accreditation and the recognition of the accreditation bodies in the more than 100 countries with which ENAC has signed agreements.

For this reason, for ENAC it is a priority objective to achieve the maximum visibility of the brand and, with it, of the accredited activities. In this sense, in 2021 an analysis was carried out to assess whether the brand that had been used for the last 25 years continued to fulfill its objective in the best possible way.

The main result of this analysis was that the great similarity between the accreditation mark and the ENAC logo could not only generate confusion among the different market agents, but also represented an inconvenience from the point of view of communication and promotion of the same reason why it was decided to undertake a change with the aim of providing the design with a greater brand appearance and, likewise, offering accredited entities an instrument adapted to the current context.

To this end, it has been decided to provide the new brand with its own visual identity, differentiated from the logo, with cleaner lines and contemporary typography, but maintaining the elements that identify the Agency, thus ensuring recognition of the brand of ENAC on the market.

Thus, the new accreditation marks that are now being presented have their own character, transversal, universal, up-to-date, but without losing the recognition obtained over the years while maintaining their link with the principle of trust that underpins the ENAC accreditation system.

The ENAC mark on reports and certificates is the guarantee of having the support of ENAC, international acceptance in more than 100 countries and official recognition in the European Union.

Certificates and reports without the Accreditation Mark do not benefit from these advantages.

To make the international character of accreditation more visible worldwide, the ILAC and IAF accrediting organizations have developed their own marks to be used in conjunction with the national marks. ENAC-accredited bodies may use these combined marks instead of the ENAC mark, although their meaning is identical to the ENAC mark.

Only those organizations that are accredited can make use of the ENAC Mark or reference to the accredited condition.

ielab gains international recognition: New ENAC brand

The ENAC brand in reports and certificates is the guarantee of having ENAC’s support, international acceptance in more than 100 countries and official recognition in the European Union.

Following the establishment of the Recognition Agreement for Proficiency Testing Schemes Providers and with the aim of making the international character of the accreditation of these activities more visible worldwide, the accrediting organizations ILAC and IAF have developed their own brands to be used in conjunction with national brands. ENAC-accredited bodies may use these combined marks in place of the ENAC mark, although their meaning is identical to the ENAC mark.

This new brand allows providers of accredited Proficiency Testing Schemes to have a means to report, not only nationally but internationally, on their technical competence. With the inclusion of these marks it is achieved that, immediately and easily, the customers and users who receive the certificate or report recognize that the organization that has issued it is internationally accredited and recognized, providing it with the necessary confidence in the veracity and technical solvency of the issuer.
