氨气报警器检定过程中的注意事项及测量值的不确定度评定
|
摘要
本文对氨气的物理特性和化学危害做了简要叙述,介绍了氨气报警器的分类和用途,根据JJG1105-2015《氨气检测仪检定规程》中的技术要求,并结合日常检定工作中的经验,给出了检定过程中的注意事项和常见问题的解决。文中分析了氨气检测报警器测量值的不确定度的主要来源,对各个分量进行分析和合成,最后给出合成标准不确定度和扩展不确定度,并给出了评定的过程。根据评定结果,采取措施,合理地减小不确定度。
This paper briefly describes the physical characteristics and chemical hazards of ammonia,and introduces the classifications and applications of ammonia alarm. According to the technical requirements of JJG1105-2015 ammonia gas detectors verification regulation,and combined with the experience of daily verification work,the matters needing attention in the verification process and the solution of common problems are given. In this paper,the main sources of uncertainty of ammonia detection alarm measurement results are analyzed,and each component is analyzed and synthesized. Finally,the uncertainty of synthesis standard and extended uncertainty are given,and the evaluation process is given. According to the evaluation results,measures should be taken to reduce the uncertainty reasonably.
