The KEYMARK - The Key to the European Market

A uniform Product Quality Mark for European Consumers

On recommendation of the European Council to improve the consumer protection and to counteract the uncertainty of consumers by a mark variety, the European Standards Organizations CEN and CENELEC have developed a harmonised European Mark System for standardized products.

The KEYMARK is the European Certification Mark showing the conformity of products and services with European Standards.

Whereas CE-marking shows the observance of legal minimum requirements, the KEYMARK provides a real surplus value for the consumer: tested and certified observance of uniform European Quality Standards. The legally requested CE-marking for certain products can be completed thereby in a meaningful way.

A product may only be marked with the KEYMARK, if it was tested and certified before by a neutral, independent and competent body. The factory inspection and Initial Type Testing (ITT), apart from the regular inspection, constitute an important element of the procedure for granting the KEYMARK.

Beyond that, the manufacturer has to carry out a Factory Production Control (FPC) in consideration of the relevant product standards and the elements of EN ISO 9001. This quality system is controlled by an annual inspection and is completed by type testing which takes place at least every 2 years.

Testing laboratories, inspection and certification bodies, taking part in the procedure, have to prove an accreditation according to relevant standards. Furthermore, certification bodies have to be empowered to grant the KEYMARK.

Since 2015, the empowerment of certification bodies, the administration of the KEYMARK and the management on behalf of CEN is assumed by DIN CERTCO.

Benefits for manufacturers and service providers
