IEC 62788-1-1:20 24定义了用于地面光伏（PV）模块中作为聚合物密封剂的非刚性聚合物材料（例如聚（乙烯-醋酸乙烯酯）、EVA）特性（光学、机械、电气、热和化学）的测试方法和报告要求。 本文件中的测试方法定义了如何以代表封装材料将如何在模块中使用的方式表征封装材料，包括与其他组件（如前片、底片、粘合剂、边缘密封或玻璃）的组合。本文件中描述的方法支持和补充了IEC 61730-2和IEC 61215-1中定义的PV模块级别的安全和性能相关测试。该文件还定义了聚合物密封剂材料特性的一般评估的测试方法。本文件中描述的测试方法可用于以下目的:数据表报告（辅助模块设计或材料研究和开发）；过程和制造控制（如进料或出料检验）；在模块安全和设计型式鉴定协议中的应用；或可靠性和耐久性研究/标准制定

IEC 62788-1-1:2024 defines test methods and reporting requirements for characteristics (optical, mechanical, electrical, thermal, and chemical) of non-rigid polymeric materials (e.g., poly(ethylene-co-vinyl acetate), EVA) intended for use in terrestrial photovoltaic (PV) modules as polymeric encapsulants.
The test methods in this document define how to characterize encapsulant materials in a manner representative of how they will be used in the module, which includes combination with other components such as frontsheets, backsheets, adhesives, edge seals, or glass.The methods described in this document support and supplement the safety- and performance-related tests defined on the PV module level, as defined in IEC 61730-2 and IEC 61215-1. This document also defines test methods for general assessment of material characteristics of polymeric encapsulants.
The test methods described in this document may be used for the purposes of: datasheet reporting (aiding module design or material research and development); process and manufacturing control (e.g., incoming or outgoing inspection); application in module safety and design type qualification protocols; or reliability and durability study/standards development
