摘要
根据GB/T 12704.2—2009《纺织品织物透湿性试验方法第2部分:蒸发法》对纺织品透湿性能进行测试,详细分析和评定测试过程中影响结果的各个不确定度分量。结果表明,不确定度主要来自于量取水的体积和读取时间的数据,其次是重复测量和称量引起的不确定度。在检测时须严格按规范操作,提高多次检测的稳定性,同时使用精确度高的称量仪器和量具。
According to the test method for water vapor transmission in textiles based on the standard GB/T 12704.2--2009 Textile-Test Method for Water-vapour Transmission of Fabrics-Part 2： Water Method, the sources of the uncertainty components effecting determination results are analyzed and evaluated. The results show that the uncertain is mainly derived from the amount of water volume and data of reading time, followed by repeated mea- surement and weighing. Accordingly, through normative operation and grasping the technique to ensure the uncer- tainty in appropriate range to effectively improve the accuracy of measuring result.
