IEC 62788-5-1 Ed. 1.0 b:2020 Measurement procedures for materials used in photovoltaic modules - Part 5-1: Edge seals - Suggested test methods for use with edge seal materials
standard by International Electrotechnical Commission, 03/19/2020
Full Description
IEC 62788-5-1:2020 provides procedures for standardized test methods for evaluating the properties of materials designed to be used as edge seals. When modules are constructed with impermeable (or extremely low permeability) front- and backsheets designed to protect moisture-sensitive photovoltaic (PV) materials, there is still the possibility for moisture to get in from the sides.
