- Abstract:
- Recent situation on global metrology is reviewed from the view point of requirements of science and technology. Basic infrastructure on quantities and units is built up under the international recognition and rules in science of measurement. Metrological traceability to a metrological reference such as a measurement unit, a reference procedure, and a reference material is considered to be fundamentals in calibration and measurement. In order to confirm the reliability of a measurement result, statement of metrological traceability chain together with attributed measurement uncertainty is required for calibration and testing laboratories. Concepts and definitions of terms are documented in such as SI brochure, VIM, GUM and some other standard documents of ISO, IEC, OIML and ILAC. In Mutual Recognition Arrangement (MRA) such as CIPM and ILAC, statements of competence for both quality management system and technology based on ISO/IEC 17025 are required. Detailed description on metrological traceability and measurement uncertainty for a measurement result is also required in many fields of science, industry and our social life from the safety point of view.
