摘　　要：根据现行国家标准GB/T 7107-2002以及GJ/T 211-2007的要求,研制出建筑外窗气密性现场检测装置,用于检测建筑门窗安装在墙体洞口后的气密性能.通过对建筑外窗气密性检测结果的不确定度评定,找出影响测量结果的主要因素,为提高检测精度提供依据.The testing device for the air permeability performance of the exterior windows was developed ,according to the national standard GB/T 7107--2002 and GJ/T 211--2007. With the device, air tightness of building exterior windows can be measured. With the testing data of this device, the uncertainty in measuring the testing results was evaluated in the article, and the principal influence factors were analyzed. It provided the basis for improving the accuracy of test.
