烟尘采样器瞬时和累积流量示值误差的不确定度评定及思考

Evaluation and reflection on uncertainty of indication error of instantaneous and accumulated flow in smoke sampler

本文对我国空气环境问题的危害、烟尘采样器量值溯源的重要性进行了讨论,根据JJG 680-2007对烟尘采样器的瞬时流量示值误差和累积流量示值误差进行了检定,并根据JJF1059.1-2012中规定的方法和要求进行检定结果的不确定度评定。

In this paper,the importance of airborne environmental problems and the importance of traceability of soot sampler are discussed.According to JJG680-2007,the instantaneous flow indication error and cumulative flow indication error of smoke and dust sampler are tested.The uncertainty of the test results is based on the method and requirements specified in JJF1059.1-2012.
