摘要
为了提高保暖袜透湿性能测试结果的有效性和准确性,对保暖袜透湿性能的不确定度进行了有效性评估,从而能更好地改善保暖袜的舒适性能。采用标准FZ/T 73054-2015《保暖袜》中透湿率的方法,对针织保暖袜的透湿性能进行了测试。在测试过程中,选取10只不同的保暖袜作为样本,重复测量10次,对该过程中的影响因素包括样品测量重复性、测试方法的正确性、设备仪器的精确性等进行逐一分析,通过计算标准差等数理统计的方法,得出不确定度的分量,最终计算出合成不确定度和扩展不确定度。所测保暖袜透湿率结果的扩展不确定度为88.98 g/(m2·24 h)。
In order to improve the effectiveness and accuracy of the test results of the moisture permeability of the thermal socks, the uncertainty of the moisture permeability of the thermal socks was effectively evaluated, so that the comfort performance of the thermal socks could be better improved. The moisture permeability of the knitted thermal socks was tested by the method of moisture permeability in the standard FZ/T 73054-2015 "thermal socks". During the test, 10 different thermal socks were selected as samples, and the measurement was repeated 10 times. The influencing factors included the repeatability of the sample measurement, the correctness of the test method, and the accuracy of the equipment instruments in the process. These factors were analyzed one by one. By mathematical statistical methods such as calculating the standard deviation, the component of the uncertainty was obtained. The synthetic uncertainty and the extended uncertainty were calculated. The expanded uncertainty of the moisture permeability of the tested thermal socks was 88.98 g/(m2·24 h).
