摘要
为测定人造板中的五氯苯酚含量,通过对LY/T 1985-2011《防腐木材和人造板中五氯苯酚含量的测定方法》的研究,得出了不确定度来源及其数学模型,对各不确定度分量进行计算,结果发现样品处理及设备重复性对不确定度贡献最大,因此应尽量提高试验结果平行性,以提高结果的准确度.
Abstract
In order to determine pentachlorophenol content in manmade board,through study on LY/T 1985-2011 Method for Determination of Pentachlorophenol Content in Preserving Timber and Manmade Board,the uncertainty source and mathematical model was obtained,the uncertainty components were calculated.The results showed that sample processing and equipment repeatability had the maximum contribution to the uncertainty,the parallelism of test results should be improved as far as possible to improve the accuracy of test results.
