DAkkS is the name of the German accreditation agency. A DAkkS calibration certificate issued by a DAkkS-accredited calibration laboratory is internationally accepted. Calibration is in accordance with DIN EN ISO 376, and hence includes measurement sequences in three different installation positions. 10 levels of force are used in the calibration (10% steps until full scale is reached). The certificate states the relative zero offset, the relative non-linearity, the relative hysteresis, the non-repeatability (in constant installation position), the relative extended comparative precision (for different installation positions) and the DIN EN ISO 376 classification. The certificate also indicates measurement uncertainties for different situations under DIN EN ISO 376. burster runs a DAkkS accredited calibration laboratory in accordance with DIN EN ISO/ IEC 17025 and also works with DAkkS-accredited partner laboratories.
