What is BS EN IEC 62788 ‑ 6 ‑ 2 about?
BS EN IEC 62788 ‑ 6 ‑ 2 is a part of a multi-series standard that deals with the performance qualifications of materials used in photovoltaic modules. BS EN IEC 62788 ‑ 6 ‑ 2 provides methods for measuring the steady-state water vapor transmission rate (WVTR), water vapor permeability (P), diffusivity (D), solubility (S), and moisture breakthrough time (Ƭ10) (defined as the time to reach 10 % of the steady-state WVTR) for polymeric materials such as encapsulants, edge seals, front-sheets and back-sheets. BS EN IEC 62788 ‑ 6 ‑ 2 gives specifications for test procedures, such as ter...
