仪器设备的期间核查是实验室认可和资质认定评审活动中必查的技术要素之一,是实验室质量控制的一种有效方式。本文以平面光栅摄谱仪的期间核查为例,结合本实验室的实际情况,对期间核查定义、期间核查与检定或校准的关系、期间核查的必要性进行了阐述,对期间核查的对象、核查的参数、核查标准的选择、核查周期或频率确定、核查方式的选择、核查结果的判定准则等方面进行了分析探讨,介绍了期间核查规程编写的要求和规则,提出了期间核查结果有效性评价的重要性,指出了实施仪器设备的期间核查既能确保仪器设备检定/校准状态的准确可靠性,又能达到质量控制的目的。
The periodical verification of equipment is one of the technical elements to be checked in the laboratory accreditation and accreditation activities and is an effective way of laboratory quality control. In this paper, the plane grating spectrometer during the verification as an example, combined with the actual situation of the laboratory, the definition of verification during the verification and verification or calibration during the relationship between the need for verification during the elaboration of the verification of the object, The parameters of verification, the selection of verification standards, the period or frequency of verification, the selection of verification methods and the criteria for the verification of verification results. The requirements and rules for the preparation of verification procedures during the period are introduced, and the validity of verification results during the period is presented The importance of the evaluation indicates that the verification during the implementation of the instrumentation and equipment can both ensure the accuracy and reliability of the verification / calibration status of the instrumentation and achieve the purpose of quality control.
