Measurement procedures for materials used in photovoltaic modules-Encapsulants. Test methods for determining the degree of cure in Ethylene-Vinyl Acetate 光伏组件用材料的测量程序
发布日期: 2020-07-29
IEC 62788的本部分定义了用于测量光伏组件中乙烯-醋酸乙烯酯(EVA)封装板固化度的术语、试验设备、试验环境、试样制备、试验程序和试验报告。本文包括差示扫描量热法(残余焓法和熔融/冷冻法)和凝胶含量法。材料或模块制造商可使用此程序验证交联添加剂是否存在且是否有效。该程序还可用于验证模块制造(层压)过程,以实现质量和过程控制。该程序还可用于评估卷内EVA配方的均匀性,以及比较不同卷之间EVA配方的变化。 该程序适用于未固化或最近固化的EVA板,以及来自光伏组件的未固化或最近固化的EVA。包含以下内容:BS EN 62788-1-6:2017
This part of IEC 62788 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.Incorporates the following:BS EN 62788-1-6:2017
