DAkkS calibration certificate or factory calibration certificate?

We are frequently asked in which cases the relatively inexpensive factory calibration certificate would be adequate in place of the more costly DAkkS certificate.

Factory calibration certificates are issued based upon the use of standards which are subjected to test equipment monitoring on a regular basis. Traceability of the utilized standards is assured by means of test equipment monitoring at regular intervals.

Factory calibration certificates are sufficient where calibration accuracy is important for the utilized measuring and test equipment, as long as it is not used as a standard.

DAkkS calibration certificates are issued based upon the use of standards whose traceability is assured by means of DAkkS certificates or calibration certificates issued by the laboratories of the DAkkS (= German national accreditation body). DAkkS calibration certificates may only be issued by calibration laboratories which have been accredited by the DAkkS and only for specifically accredited measured quantities. This assures the maintenance of high standards of calibration quality by means of regular audits, traceable standards, precisely defined ambient conditions and specially trained personnel. These cost and personnel-intensive measures result in a higher price, but they also assure the reliability required for correct measuring results.

Due to guaranteed traceability to national standards, DAkkS calibration should be used for the re-calibration of test equipment which itself is used as a standard for the monitoring of other measuring and test equipment.
