The IEC 62788 series covers various measurement procedures for materials used in photovoltaic modules.
PD IEC/TS 62788-2 is the second part of the series that defines test methods and datasheet reporting requirements for safety and performance-related properties (mechanical, electrical, thermal, optical, and chemical) of non-rigid polymeric materials intended for use in terrestrial photovoltaic modules as polymeric front sheets and back sheets.
The test methods in PD IEC/TS 62788-2 define how to characterize back sheet and front sheet materials and their components in a manner representative of how they will be used in the module, which eventually includes a combination with other matched components such as encapsulant or adhesives.
PD IEC/TS 62788-2 on measurement procedures for materials used in photovoltaic modules useful to:
Datasheet reporting of plastics and polymers used in photovoltaic modules is required to ensure that materials and products perform as expected and last as long as possible.
Improve the performance of photovoltaic modules by adopting PD IEC/TS 62788-2 test procedures datasheet reporting requirements for safety and performance-related properties of non-rigid polymeric materials.
The methods described in PD IEC/TS 62788-2 support the safety and performance-related tests defined on PV module-level as defined in the series IEC 61730 and IEC 61215.
PD IEC/TS 62788-2 defines test methods for assessment of inherent material characteristics of polymeric backsheets and frontsheets or their components, which may be required in datasheet reporting or can be useful in the context of product development or design of PV modules.
