JJF1069—2003《法定计量检定机构考核规范》的7.5.3.3中对“期间核查”规定为:应根据规定的程序和日程对计量基(标)准、传递标准或工作标准以及标准物质进行核查,以保持其检定或校准状态的可信度。这一概念及要求实际上就是实验室自身对其测量标准应根据作业指导书,按照事先确定的期间核查计划进行技术检查,以确保其检定/校准状态的置信度。有不少实验室由于对这一概念理解不到位,在实施过程中遇到一些困难,本文以实例对“期间核查”的程序及实施作一些个人的见解。
JJF1069-2003 “Statutory metrology institutes examination norms,” the 7.5.3.3 of the “period of verification” provides that: should be based on the prescribed procedures and schedule measurement basis (standard), transfer standards or standards of work and the standard material verification, To maintain its verification or calibration of the credibility of the state. This concept and requirement is actually the laboratory itself should be based on the measurement standards operating instructions, according to a predetermined period of time to verify the technical inspection plan to ensure that the verification / calibration status of the confidence. Many laboratories have encountered some difficulties in the process of implementation due to the lack of understanding of this concept. This article gives some personal views on the procedure and implementation of “period verification” by means of examples.
