The Perfect Weight HÄFNER sets standards worldwide with high-quality weights and highly accurate dimensional standards. A wide variety of industries, institutes and authorities trust our accredited expertise. Because they know: HÄFNER stands for perfection. In every calibration, every test and adjustment. 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 for mass, solid density and solid volume; registration no. D-K-15192-01-00). The DAkkS is a full member of the following European and international accreditation organisations: EA (European co-operation for Accreditation), IAF (International Accreditation Forum) and ILAC (International Laboratory Accreditation Cooperation). Through multilateral agreements and conventions of the national accreditation authorities with the European or international accreditation organisations (EA MLA, IAF MLA und ILAC MRA), the mutual recognition of the services and results of accredited authorities is made possible. Our calibration work and calibration certificates thus receive international recognition. Our calibration laboratory MASSCAL is a member of the DKD (German Calibration Service). Through active participation in the DKD's "Mass" technical committee and intensive cooperation with the PTB (Physikalisch-Technische Bundesanstalt), HÄFNER is always at the cutting edge of science and technology.
