摘要
为了确保检测结果的准确性和实验的重复性,依据JJG1059-1999《测量不确定度评定与表示》,采用GB/T19941-2005《皮革和毛皮化学试验甲醛含量的测定分光光度法》对裘皮制品中的甲醛进行定量检测,本研究详细分析了该检测方法在检测过程中的各个环节影响检测结果的分量,并对所涉及的分量进行了评定,最终得出结论:裘皮制品中甲醛检测测量不确定度评定主要来源于标准储备液不确定度和曲线拟合过程中系列配制所产生的不确定度。
In order to improve the accuracy and repeatability of test results ,according to the method of GB/T 19941-2005 and the method of JJG 1059-1999, uncertainty in formaldehyde content measurement was evaluated. Finally, the result of determination of formaldehyde in Fur Products suggests that the main causes of uncertainty that affect the determination results are the stock solution of formaldehyde and preparation of formaldehyde standard series.
