The legal foundationsfor DAkkS are Regulation (EC) No. 765/2008 and the German Federal AccreditationLaw (AkkStelleG).DAkkS is the successor to DKD (Deutscher Kalibrierdienst) for calibration laboratories.As a joint governmental-industrial body,DAkkS represents a link between the nationalstandards established by Germany'sPTB (Physikalisch-Technische Bundesanstalt)and the measuring instruments usedin industrial and research laboratories, andby testing institutions and authorities.It thus effectively complements the existingverification system, the primary focus ofwhich is consumer protection.DKD – well-known name, completelynew functionFollowing the establishment of DAkkS,DKD is no longer active in accreditationmatters, and it was reconstituted in 2011with a new mission under guidance fromthe PTB. Since that time, DKD has beenresponsible for further developing thefundamentals of metrological calibration,expanding technical support, and promotingstandardization in metrology.DAkkS calibration laboratoryThe former DKD calibration laboratory at BRAND for volumetric instruments was changedinto an accredited calibration laboratory by the DAkkS according to DIN EN ISO/IEC17 025. The calibration laboratory at BRAND is therefore authorized to issue DAkkS calibrationcertificates for the following volumetric instruments. They are available in severallanguages.BRAND calibrates the following volumetric instruments, no matter if they are new or alreadyin use:For ordering volumetric instrumentswith DAkkS calibrationcertificate, add "DAkkS" as aprefix to the catalog number.To obtain a DAkkS calibrationcertificate for volumetric instrumentsalready in use (regardlessof their make), send the instrumentsto BRAND marked withthe note "DAkkS calibration".■ Piston-operated pipettes,from 0.1 µl to 10 ml■ Multichannel piston-operatedpipettes, from 0.1 µl to 300 µl■ Piston-operated burettes,from 5 µl to 200 ml■ Dispensers, dilutors,from 5 µl to 200 ml■ Glass volumetric instruments,adjusted to contain (TC, In)from 1 µl to 10 l■ Glass volumetric instruments,adjusted to deliver (TD, Ex)from 100 µl to 100 ml■ Plastic volumetric instruments,adjusted to contain (TC, In)from 1 ml to 2000 ml■ Plastic volumetric instruments,adjusted to deliver (TD, Ex)from 1 ml to 100 ml■ Glass density bottles,from 1 cm 3 to 100 cm 3A major difference between works calibration services and DAkkS laboratories is the accuratedetermination of the respective uncertainty of measurement guaranteed by the accreditedlaboratory and supervised by the DAkkS.DAkkS calibration certificateThe DAkkS calibration certificate documents officially the traceability of measuring resultsto national and international standards as required by the standards DIN EN ISO 9001 andISO/IEC 17 025 for the monitoring of measuring instruments.When is a DAkkS calibration certificate necessary?DAkkS calibration certificates are appropriate in uses in which calibrations of an accreditedlaboratory are requested, where high level calibrations are demanded and for calibration ofreference standards and instruments for comparative measurements.328info@brand.de
