Under a certain test temperature, a constant humidity difference is generated between two sides of the test specimen. The water vapor permeates through the specimen and into the dry side. By measuring the weight changes of the test dish in different time, water vapor transmission rate and other parameters can be obtained.
water vapor transmission rate—the steady water vapor flow in unit time through unit area of a body, normal to specific parallel surfaces, under specific conditions of temperature and humidity at each surface.” 4. Summary of Test Methods 4.1 .ABSTRACT: The oxidation of calcium films by water vapor is the basis of the “Ca test” used to measure low water vapor transmission rates (WVTRs) through gas diffusion barriers. The Ca test assumes that the Ca film oxidation rate is linear with H 2 O flux transmitted through the barrier. However, lag times are often observed during WVTR .C406H Oxygen /Water Vapor Transmission Rate Test System. ⚫ In the test process, the automatic control on flow, temperature and relative humidity is realized, reaching higher accuracy.
