ESTABLISHMENT OF TRACEABILITY FOR THERMOPHYSICAL PROPERTY DATA AND DEVELOPMENT OF THEIR DATABASE
In this decade, National Metrology Institute of Japan (NMIJ), AIST has been devoted to reinforcement of metrological standards by establishing more than 250 new physical standards and 250 new reference materials as technical infrastructure responding to mutual recognition arrangement for increasing international trade and to global approach for safety, health, energy, and environmental issue. As a part of this effort, standards and traceability for thermophysical property measurements have been developed and, consequently, thermophysical property data traceable to the national standard can be produced systematically, continually, and efficiently (Baba et al., 2010 to be published). Uncertainty of these data can be evaluated based on the guide for expression of uncertainty in measurement (GUM) (ISO/IEC Guide 98-1:2009). If a material is characterized and identified quantitatively enough, traceable thermophysical property data for the material with uncertainty produced by above mentioned scheme can be accepted as reliable and universal information. Thus, accumulation of these data is expected as important scientific and technical infrastructure to contribute sustainable development of the world (Ono et al., 2001). We report a new type of database, which is optimized to store and evaluate traceable thermophysical property data with uncertainty and material identification, developed by NMIJ under this concept and scheme in collaboration with Japan Society on Thermophysical Properties (JSTP) (Baba, Yamashita, Nagashima, 2009).
