摘要
期间核查是实验室质量控制的重要手段,能够有效弥补仪器设备在校准周期之间可能出现的性能变化监测空白,国内外的实验室认可机构和资质认定部门,都明确规定实验室应当建立并实施期间核查程序。本文介绍了梳状波发生器的特点,明确了EMC发射系统期间核查对梳状波发生器的参数要求,分析了期间核查的具体流程,详细论述了期间核查的实施要点,旨在为实验室的期间核查工作提供帮助。
Intermediate check is an important means of laboratory quality control,which can effectively fill the monitoring gaps for possible performance changes of instruments and equipment between calibration cycles.Both domestic and foreign laboratory accreditation bodies(such as the China National Accreditation Service for Conformity Assessment,CNAS)and qualification certification departments clearly stipulate that laboratories should establish and implement intermediate check procedures.This article introduces the characteristics of the comb generator,clarifies the parameter requirements of the comb generator for intermediate check of the EMC emission system,analyzes the specific process of intermediate check,and elaborates on the key points of implementing intermediate check,which is expected to provide assistance for the intermediate check work of laboratories.
