摘要
阐述了测量不确定度评估的意义,并以盐雾试验为例,评估测量不确定度分量如配置盐溶液、盐溶液PH值、盐雾沉积量、试验箱温度、样品的放置与恢复条件、试验后的检测等对盐雾试验结果的影响,提出了控制各分量的措施。
The significance of evaluation of uncertainty of measurement was expatiated.As a sample,the uncertain quantities of measurement affecting salt spray test result were evaluated, including collocating salt solution,PH valure of salt solution,salt spray deposition, temperature of chamber, condition of placement and recovery sample, test after salt spray test,etc.Some measures controlling each quantities were also put forward.
