Research on Air Tightness Performance of Building Exterior Door and Window System Based on Measurement Uncertainty Evaluation
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.
