建筑排水用硬聚氯乙烯(PVC-U)管材拉伸屈服强度检测结果的不确定度分析

Construction draining water(PVC-U) the tubing stretches the yield strength test results with the hard polyvinyl-chloride of uncertainty analysis

对建筑排水用硬聚氯乙烯(PVC-U)管材拉伸屈服强度检测结果的不确定度进行评定,分析不确定度产生的来源,影响因素及过程计算,得到不确定度范围,使之在检测工作中进行质量控制,确保测量结果更为准确。

The stretch yield strength of the construction draining water uses the hard polyvinyl-chloride（PVC-U） the tubing to evaluate the uncertainty arite,influencing factors and the process,theobtained uncertainty range,so that thework in the detection of control,more accurate measurements.
