BS EN 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. This procedure can be
applied to uncured or recently cured EVA sheet as well as uncured or recently cured EVA from
PV modules.
This test procedure can also be applied to cross-linking ethylenic co-polymers other than EVA.
The temperatures identified for the calorimetry measurements in this procedure have been
optimized for EVA. Therefore, if the test procedure is applied to other encapsulation materials,
the range of the test temperatures can have to be adjusted based on the active temperature of
the curing agent and/or the melt/freeze temperature of the base material.
