TPO防水卷材拉伸强度测试的不确定度评定

Evaluation on measurement uncertainty of tensile strength of TPO waterproofing membrane

通过对热塑性聚烯烃(TPO)防水卷材拉伸性能进行实验,发现影响拉伸强度测试结果的主要因素为重复性实验和拉力值测试,并对检测结果的不确定度进行了评定。

This article analyses measurement uncertainty of tensile strength of TPO waterproofing membrane,the results indicat- ed that repeated experiments and tension values measured are the main factors affecting the tensile strength measurements of the TPO waterproofing membrane. And the uncertainty of test results was also evaluated in this study.
