安全监测设备校准用标准气体质量安全风险研究

Research on the Quality and Safety Risk of standard Gas Used in the Calibration of Safety Monitoring Equipment

对市场上流通的部分氮中一氧化氮、氮中二氧化氮、氮中硫化氢三类安全监测设备校准用气体标准物质进行采样,并使用一级标准物质进行标称值的检测和比对。对测试过程进行了不确定度评定,通过显著性分析来确定市售二级标准物质的标称值与实测值之间是否有显著性差异,并对该结果可能产生的事故风险进行了评估。从结果来看,标称值不准确的气体标准物质在市场流通会对生产活动造成一定的风险,需要有关监管部门加大重视力度。

In this essay,some of the nitrogen monoxide in nitrogen,nitrogen dioxide in nitrogen,and hydrogen sulfide in nitrogen three types of gas reference materials for calibration of safety monitoring equipment in the market were sampled,and the primary reference materials were used for the detection and comparison of the nominal value.The uncertainty of the test process was evaluated,and the significance analysis was used to determine whether there was a significant difference between the nominal value of thecommercially available secondary reference material and the measured vaLue,and the pos-sible accident risk of the result was evaluated.From the results,the circulation of gas reference materials with inaccurate nominal values in the market will cause certain risks to production activities,and relevant regulatory authorities need to pay more atention.
