Chemical Measurement Traceability

摘要

Traceability of chemical measurements is handled in a variety of ways by testing laboratories and calibration laboratories. For many laboratories, the ways of ensuring traceability do not meet the requirements of ISO/IEC 17025. The measurements are presumed to be traceable to a national standard, but the proof of the traceability is not always complete. Outdated industry applications of traceability are often found in laboratories since chemical measurements have not been the focus, until now. The recent need for traceability of chemicals has resulted in new discussions and presentations to improve the industry standards for chemical measurement traceability.
