Difference between Traceability and Certificate of Calibration?
The major difference between the Report of Traceability and the Calibration Certificate is the Report of Traceability is a tolerance test and is only available for new weights. The Certificate of Calibration is a full report of the parameters tested. The Certificate of Calibration will, however, give a smaller uncertainty and a more precise value of the actual mass due to the multiple measurements that are made during the calibrating process. If you require a accredited laboratory certificate to meet ISO/IEC 17025 & ANSI/NCSC Z540-1 then you need a NVLAP Certificate of Calibration and you should NOT buy this weight set since it includes only a Report of Traceability
We offer a choice of 21 and 9 piece weight sets or individually weights ranging from 5kg to 1mg. See the complete offering of calibration weights here.
