Annotation of standard text IEC 62788-1-6-ed.1.0 :
IEC 62788-1-6:2017 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. The procedure can also 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. L’IEC 62788-1-6:2017 definit la terminologie, lequipement dessai, lenvironnement dessai, la preparation des eprouvettes, les procedures dessai et le rapport dessai pour le mesurage du degre de durcissement de la couche dencapsulation en ethylene-acetate de vinyle (EVA) utilisee dans les modules photovoltaiques (PV). Les methodes de lanalyse calorimetrique differentielle a balayage (protocoles denthalpie residuelle et de fusion/gel) et du taux de gel sont incluses dans le present document. Cette procedure peut etre utilisee par les fabricants de materiaux ou de modules pour sassurer que ladditif de reticulation est present et actif. La procedure peut egalement etre utilisee pour verifier le procede de fabrication (stratification) du module a des fins de controle de la qualite et des processus. Elle peut en outre etre utilisee pour evaluer luniformite de la formulation d’EVA dans un rouleau et comparer les differences de formulation d’EVA dun rouleau a lautre.
