금속소재의 참조표준 평가기준 개발

"Reference standards" are usable data to be used repeatedly, widely and continuously in all fields. They are authorized by analyzing scientifically and estimating the accuracy and reliability of measurement data and information. They are physical-chemical constants, authorized properties, authorized scientific- technological statistics, etc. Reference standards are national infra in connection with almost industry field as well as basic scientific technique fields. To develope reference standards evaluation system for tensile properties of metallic materials, evaluation procedure and criterion of tensile properties of metallic materials were described briefly in this study.
