Measurement procedures for materials used in photovoltaic modules - Part 1-6: Encapsulants - Test methods for determining the degree of cure in Ethylene-Vinyl Acetate
Measurement procedures for materials used in photovoltaic modules - Part 1-6: Encapsulants - Test methods for determining the degree of cure in Ethylene-Vinyl Acetate.
IEC 62788-1-6:2017+A1:2020 defines the terminology, test equipment, test environment, specimen preparation, test procedures, and test report for measuring the degree of cure of Ethylene-Vinyl Acetate (EVA) encapsulation sheet used in photovoltaic (PV) modules.
The differential scanning calorimetry (both residual enthalpy and melt/freeze protocols) and gel content methods are included herein.
This procedure can be used by material- or module-manufacturers to verify that the cross-linking additive is present and is active.
The procedure can also be used to verify the module manufacturing (lamination) process for the purposes of quality- and process-control.
Additionally, the procedure can be used to assess the uniformity of the EVA formulation within a roll as well as to compare variation of the EVA formulation from roll to roll.
This consolidated version consists of the first edition (2017) and its amendment 1 (2020). Therefore, no need to order amendment in addition to this publication.
