Cooperation and Competition Following International Mutual Recognition-The World after the Conclusion of CIPM-MRA

摘要

In recent years, a key word of "globalization" is advancing for good or for bad. This trend is not limited to economy. The metrology has originally had an international nature. In 1999, the International Committee for Weights and Measures concluded a mutual recognition agreement (CIPM-MRA). After this, more international co-operations are requested and competitions are more intense, because this agreement has been intended to guarantee mutual equivalence. It was agreed to publicly announce the results of international key comparisons and list up the calibration items and their CMCs (Calibration and Measurement Capabilities). The data of each country is released from the website of International Bureau of Weights and Measures as KCDB (Key Comparison Database) (http://kcdb.bipm.org/). CIPMMRA has been signed now by 75 economies and three international organizations. In this KCDB, 703 international key comparisons, 248 supplementary comparisons and a total of 23,184 CMCs have been registered. The table shows the total number of CMCs, number of international comparison participation, and number of pilot laboratories undertaken for these comparisons. These figures indicate the " capability" of the countries in metrology as result of the conclusions of CIPM-MRA.
