| Abstract: | Objective:To evaluate the data consistency of water vapor permeation of plastic films by three analytical methods, including cup method, electrolytic detection sensor method and infrared detection sensor method. Methods:Three analytic methods were used separately to determine the water vapor permeation of plastic films with uniform thickness. Then an equivalence test was used to evaluate the consistency of the data gained by using three methods. Results:The measurement of water vapor permeation of plastic films determined by cup method, electrolytic detection sensor method and infrared detection sensor method was 7.03, 7.02 and 6.99 g/(m2·day) respectively. Conclusion:The data obtained by using three methods were equivalent, which provided a good basis for comparison of laboratory data for measuring water vapor permeation of plastic films. |
