초록

정밀측정장비의 성능을 진단 및 확인하는 교정 시스템은 교정결과의 신뢰성 확보를 위해 국제규격의 요구조건을 준수함으로 교정결과의 오판정 위험을 최소화하고 있다. 본 논문에서는 교정기관에서 고성능의 장비를 획득 및 운영하기에 불가능한 경우 불확도 요인 분석을 통한 교정 시스템 적합성 평가 방안과 가드밴드 기법을 이용하여 성능기준을 대체하는 최적화된 시험기준 산출모형을 제안한다. 제안된 방법은 교정 시스템의 정량적인 평가기준과 국제규격에서 요구되는 허위수락위험 확률 기준을 충족을 위한 최적화된 시험기준을 제공한다.

A calibration system for diagnosing and confirming the performance of precision measuring instruments minimizes the risk of misjudgment of calibration resulted by complying with international standard requirements in order to ensure the reliability of calibration results. This paper uses a proposed calibration system suitability assessment and a guard-band technique through an analysis of uncertainty factors when it is impossible to acquire and operate high-performance equipment at a calibration laboratory, and proposes an optimized test limit output model substituting performance standards. The proposed method provides an optimized test standard to meet the quantitative evaluation criteria of the calibration system and the probability of false acceptance risk required by international standards.
