HÄFNER short portrait
HÄFNER's quality management system was introduced as early as 1998. It is certified by DQS GmbH (German Society for the Certification of Management Systems) according to DIN EN ISO 9001:2015 (Reg. No. 059 993 QM15).
Our calibration laboratory "MASSCAL" complies with the international standard DIN EN ISO/IEC 17025:2015 and is accredited by DAkkS (German Accreditation Authority; Registration No. D-K-15192-01-00). DAkkS is a full member of the following European and international accreditation organizations: EA (European co-operation for Accreditation), IAF (International Accreditation Forum), and ILAC (International Laboratory Accreditation Cooperation).
Through multilateral agreements and conventions of national accreditation bodies with European and international accreditation organizations (EA MLA, IAF MLA and ILAC MRA), mutual recognition of services and results of accredited bodies is ensured. Our calibration services and certificates therefore receive international recognition.
Our calibration laboratory MASSCAL is a member of the DKD (German Calibration Service). Through active participation in the "Mass" technical committee of the DKD and close cooperation with the PTB (Physikalisch-Technische Bundesanstalt), HÄFNER is always at the cutting edge of science and technology.
