摘 要：由于真值不可能通過測量得到，借助測量不確定度可以了解到被測量值在什么范圍內(nèi)，所以試驗(yàn)室有必要對測量結(jié)果的不確定度進(jìn)行評定。本文根據(jù)JJF 1059.1-2012《測量不確定度評定與表示》和GB 18352.6-2016《輕型汽車污染物排放限值及測量方法（中國第六階段）》附錄F的規(guī)定，對試驗(yàn)室開展的蒸發(fā)污染物排放試驗(yàn)測量結(jié)果進(jìn)行了不確定度分析評定。

Abstract：The truth value of an ideal concept cannot be measured， while the range of measurements can be known via the evaluation of uncertainty in measurement. It is necessary to evaluate the uncertainty of measurement results for the laboratory. According to JJF 1059.1-2012 Evaluation and Expression of Uncertainty in Measurement and Appendix F of GB 18352.6-2016 Limits and Measurement Methods for emissions from Light Vehicle Pollutants （China 6）， this paper evaluates the uncertainty in measurement of evaporation emission results for the laboratory.

Key words：measurement， evaporative emissions test， uncertainty
