摘要
作为省级计量检定机构,我所使用的计量标准装置都需经上级计量检定机构根据计量标准考核规范,考核合格,发放相应的检定/校准证书,方可开展计量检定工作。我所大流量检定站所使用的计量标准装置———标准表法空气流量标准装置。经上级检定机构考核合格,给出扩展不确定度:U=0.3%,k=2。作为一名计量检定人员,对所使用的计量标准装置,从构造原理到技术指标都要做到心中有数。
Qinghai Metrological Verification Test Institute as the provincial metric calibration organizations, the used metering standard device need to be validated by metric calibration organizations at a higher level according to the examination standard of measurement standard and if it is qualified, the metric calibration organizations at a higher level would issue the corresponding validation or calibration certificate, and then carry out the work. We have large flow of metering standard device used by the verification station--standard meter method air flow standard equipment. After approved by the metric calibration organizations at a higher level, it gives the extended uncertainty： U=0.3%,k=2. As a verification officer, we should have a pretty clear idea from the structural principle to technical indicators.
