Traceability and the JCSS System-The Spread of Measurement Literacy and the Expansion of Calibration Laboratories

摘要

As mentioned in other articles in this issue, NMIJ continues establishment of physical standards and reference materials based on the Intellectual Infrastructure Improvement Plan. The scene where these standards are used in the industrial world is increasing. The two factors that contributed to such a result are mentioned below.The first factor is cooperation with external organizations. The goal of the Intellectual Infrastructure Improvement Plan was to reach the same level of intellectual infrastructure as there is in foreign countries. But, national metrology institutes such as the U.S. National Institute of Standards and Technology (NIST) and the German Physikalisch-Technische Bundesanstalt (PTB) have a far larger scale than NMIJ. A level comparable to these nations cannot be reached by NMIJ alone.
