IEC 62788-1-6:20 7+A1:2020定义了测量光伏（PV）组件中使用的乙烯-醋酸乙烯酯（EVA）封装片固化程度的术语、测试设备、测试环境、样品制备、测试程序和测试报告。本文包括差示扫描量热法(残余焓和熔融/冷冻方案两者)和凝胶含量方法。材料或模块制造商可以使用该程序来验证交联添加剂的存在和活性。该程序还可用于验证模块制造（层压）工艺，以达到质量和工艺控制的目的。该程序还可用于评估卷内EVA制剂的均匀性以及比较卷与卷之间EVA制剂的变化。该合并版本由第一版（2017年）及其修正案1（2020年）组成。因此，除本出版物外，无需下令修订。

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. 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 consolidated version consists of the first edition (2017) and its amendment 1 (2020). Therefore, no need to order amendment in addition to this publication.
