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.
