BS PD IEC/TS 62788-2:2017 defines test methods and datasheet reporting requirements for safetyand performance related properties (mechanical, electrical, thermal, optical and chemical) ofnon-rigid polymeric materials intended for use in terrestrial photovoltaic modules as polymericfrontsheets and backsheets.
The test methods in this document define how to characterize backsheet and frontsheetmaterials and their components in a manner representative of how they will be used in themodule, which eventually includes combination with other matched components such asencapsulant or adhesives. The methods described in this document support the safety andperformance related tests defined on PV module level as defined in the series IEC 61730 andIEC 61215.
This document also defines test methods for assessment of inherent material characteristicsof polymeric backsheets and frontsheets or their components, which may be required indatasheet reporting or may be useful in the context of product development or design of PVmodules.
