for test weights, class E2, 1 mg - 500 mg
Calibrated measuring equipment requires calibrated checking equipment. For balances, these are calibrated test weights, also called 'standard weights'. The issued DAkkS calibration certificates are proof of the metrological traceability to national and international standards, as required by the DIN EN ISO 9000 and DIN EN ISO/IEC 17025 standards, amongst others.
