木质平托盘用胶合板甲醛释放量测定不确定度分析

摘要

从随机效应和系统效应两个方面,依据JJF 1059—1999《测量不确定度评定与表示》及CNAS—GL05：2006《测量不确定度要求的实施指南》对胶合板甲醛释放量的检测结果进行了不确定度的评定,并对评定结果进行了分析。结果显示：对于该被测量估计值,在95%的置信水平下,扩展不确定度为0.11 mg/L,其中贡献最大的分量为随机效应带来的分量,其次是量值数值修约带来的分量。%The presented article evaluated the uncertainty of the determination of formaldehyde emission from plywood pallets,from random and system effects,following two standards：JJF1059—1999 The expression of uncertainty in measurement and CNAS—GL05：2006 The implementation guide of the requirements of measurement uncertainty.The results indicated that：when the confidence level is 95%,the expanded uncertainty is 0.11 mg/L.The most significant contribution factor was random effects,followed by rounding off of numerical values.
