Through the evaluation and analysis of the measurement uncertainty introduced by the air tightness performance test stipulated in ASTM E283/E283M-19 and GB/T 7106-2019,combined with tests,the difference of the test results of the air tightness performance of the door and window system under different evaluation systems was studied.The results showed that:When the measurement uncertainty is introduced,the measurement uncertainty of ASTM E283/E283M-19 airtight performance test method with the corrected air density correction factor is less than the measurement uncertainty of GB/T 7106-2019 airtight performance grading test method.And the test results of ASTM E283/E283M-19 on air leakage rate are smaller than those of GB/T 7106-2019.
