Traceability, Accreditation, Measurement Accuracy: How to Get It and How to Keep It!
C S. Brickenkamp, E L. Garner
Many of us in the scientific and technological arenas are measurement middlemen taking measurements provided by others, and making measurements for others. This discussion is intended to explore traceability and the value of accreditation in the context of the rapidly changing global marketplace of measurements and measurement services:* Measurement users and measurement makers need first to find out how accurate their measurements must be, that is, how much uncertainty they can tolerate in their measurements.* Requiring measurements to be traceable using the current international definition of traceability can provide assurance that measurements meet accuracy needs.* Because the task of determining whether measurements are traceable can be somewhat formidable and time consuming, there is enormous value added by requiring accreditation of measurement providers.
