Quality management

HÄFNER works according to a quality management system and is certified by DQS according to DIN EN ISO 9001:2015 (Reg. No. 059 993 QM15).

Our calibration laboratory "MASSCAL" (D-K-15192-01-00) complies with the international standard DIN EN ISO/IEC 17025:2018 and is accredited by the Deutsche Akkreditierungsstelle GmbH (DAkkS). This gives our calibration certificates international recognition.

Due to our active participation in the technical committee "Mass" of the German Calibration Service (DKD) and the intensive cooperation with the Physikalisch-Technische Bundesanstalt (PTB) we are always up to date with the latest state of science and technology.
