HÄFNER works in accordance with a quality management system and is certified by “Deutsche Gesellschaft zur Zertifizierung von Managementsystemen” (DQS) in accordance with DIN EN ISO 9001 (Reg. No. 059 993).

Our calibration laboratory "MASSCAL" fulfils the international norm DIN EN ISO/IEC 17025 and is accredited (Reg. No. D-K-15192-01-00) by DAkkS (Deutsche Akkreditierungsstelle / German Accreditation Body).
DAkkS is a member of the international accreditation organisations: European co-operation for Accreditation (EA), International Accreditation Forum (IAF) and International Laboratory Accreditation Cooperation (ILAC). A key objective of the international accreditation network is the mutual recognition of the services and results of accredited bodies in order to prevent technical obstacles and multiple accreditations.

This is made possible by multilateral agreements and treaties (MRA or MLA) between the national accreditation bodies and the international accreditation organisations. It creates both national and international recognition that e.g. each laboratory accredited by DAkkS is able to conduct certain calibrations in a competent manner.  Our calibration service and certificates are getting international recognition.

Furthermore, MASSCAL is a member of DKD (Deutscher Kalibrierdienst / German Calibration Service). Through our active cooperation in the technical committee on "Mass and Weighing Instruments" of DKD (Deutscher Kalibrierdienst) and the intensive cooperation with the Physikalisch-Technische Bundesanstalt (PTB) we are always at the cutting edge of science and technology.
