摘要

1m,3,气候箱法是人造板甲醛释放量测定的主要方法之一。为探究检测过程中的误差来源,提高测量结果的准确度,从1m,3,气候箱法检出限及不确定度等方面进行研究。结果表明:50 mm光程比色皿的检出限较低,适宜后续甲醛释放量测试时采用;对于低甲醛释放量的人造板样品,重复测量引入的不确定度对总体不确定度的贡献最大。

Abstract

The 1 m,3, climate chamber method is one of the main and important tools to determine formaldehyde emissions from wood-based panels.In order to improve the accuracy of test results,the detection limits and uncertainty of the 1 m,3, climate chamber method were studies.The results showed that the detection limit of a 50 mm optical path colorimeter was not very high,which would be suitable for following formaldehyde emission tests.As for wood-based panels with low formaldehyde emissions,the uncertainty derived from duplicated measurements took a major contribution to the overall uncertainty.
