建筑门窗气密性能检测结果不确定度分析

Uncertainty Analysis of Result of Building Doors and Windows Airtight Performance

测量不确定度是指根据所用到的信息,表征赋予被测量值分散性的非负参数。通过对检测结果不确定度分析,一方面能检查检测工作是否存在差错,另一方面能评价检测中何种分量对检测结果影响最大,通过加以控制,能减轻检测人员和检测机构风险,更有利于检测结论的判定。依据GB/T 7106-2008《建筑外门窗气密、水密、抗风压性能分级及检测方法》,在实验条件下进行建筑门窗的气密性能测试,并对其检测结果的不确定度进行分析评定。

Measurement uncertainty showed the non-negative parameter of measured value range according to the mentioned information. By analyzing the uncertainty of testing result, on the one hand can check whether there was any error in detection work, on the other hand can evaluate what weight the biggest influence on test results in detection, through the control can reduce the inspection personnel and institutional risk, which is more advantageous to the judgment of test conclusion. According to GB/T 7106- 2008 ＂Building outside the window, wind resistance, airtight, watertight classification and detection methods＂, under the experimental conditions for building doors and windows, airtight performance test and the test results of uncertainty evaluation for analysis.
