Development and implementation of a database system for the comparison of international measurement standards and national systems of traceability

Worldwide access to data from comparisons of national measurement standards is now needed to ensure the comparability of measurements between national and regional systems of metrology. Measurement and calibrations data need to be accessed to ensure the integrity and strength of traceability links within a region of country. The National Institute of Standards and Technology, in cooperation with other National Metrology Institutes (NMIs) has developed an International Comparisons Database (ICDB) system to answer these needs. Design features of the system and its WEB interface will be described as well as examples of how data from comparison participants can be compared.
