摘　　要：根据《测量不确定度评定与表示技术规范》(JJF 1059.1-2012)的要求,系统地对浸渍纸层压木质地板吸水厚度膨胀率的测量结果不确定度进行了评定。针对浸渍纸层压木质地板吸水厚度膨胀率试验中的测量不确定度的特点,分析了试验过程中影响测量准确性的因素。结果表明:试验条件下的浸渍纸层压木质地板吸水厚度膨胀率测量结果的扩展不确定为0.7%。The uncertainty of measurement results of thickness swelling rate of water absorption for laminate flooring was systematically evaluated according to the requirement of JJF1059. 1- 2012. Some factors influencing the precision were analyzed in the experiments aimed at the characteristics of the measurement uncertainty of thickness swelling for laminate floor covering. Results showed that the expanded uncertainty of thickness swelling rate of water absorption for laminate floor was 0. 7% under laboratory conditions.
