Measurement procedures for materials used in photovoltaic modules - General tests. Moisture permeation testing of polymeric materials Ingestion-build-86103 Household range hoods or cooking1 Scope This document 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
