PROBLEM TO BE SOLVED: To retrieve quickly a calibration certificate from a field measuring apparatus to a national standard for reliability certification of a measurement result. SOLUTION: In a metering standard traceability system for tracing from a measuring apparatus to a national metering standard, an address is added to a metering standard for calibrating the measuring apparatus, and information (an attribute, a calibration value, a calibration certificate, and by which host reference standard a metering standard at a calibration time is calibrated, or the like) of a calibration implement is exhibited on the Internet (including a membership system Web), and the host reference standard is retrieved on the Internet, and traced successively up to the national standard, and reliability certification of the measurement result is performed quickly by retrieval of linkage of the calibration certificate.
