摘要
依照JJF1059.1-2012《测量不确定度的评定与表示》的方法,对细木工板甲醛释放量测量试验进行了不确定度分析,并对各不确定度分量进行量化和评定,计算了合成标准不确定和扩展不确定度。结果表明:甲醛释放量为(1.3±0.2)mg·L^(-1),其中扩展不确定度的包含因子k=2,置信概率P=95%。
Based on JJF1059.1-2012 Evaluation and Expression of Uncertainty in Measurement,the uncertainty for determination of formaldehyde emission of blockboard was analyzed.Uncertainty components of measurement were made sure by calculation.The combined uncertainty and expanded uncertainty were calculated.The results showed that formaldehyde emission was（1.3±0.2）mg·L-（-1）,which expanded uncertainty coverage factor k=2,fiducially probability P=95%.
