General tests - Moisture permeation testing of polymeric materials

IEC 62788-6-2:2020 provides methods for measuring the steady-state water vapour transmission rate (WVTR), water vapour permeability (P), diffusivity (D), solubility (S), and moisture breakthrough time (10) (defined as the time to reach 10% of the steady state WVTR) for polymeric materials such as encapsulants, edge seals, frontsheets, and backsheets.

These measurements can be made at selected temperatures and humidity levels as deemed appropriate for evaluation of their performance in PV modules.

Measurement is accomplished by inspection of the transient WVTR curve and by fitting it to a theoretical Fickian model.

This document is best applied to monolithic films. If multilayer films are used, the D and S values are only apparent values, but the steady-state values can still be measured.
