ActiveTest method for determining the content of vinyl acetate in ethylene-vinyl acetate copolymer applied in photovoltaic modules—Thermal gravimetric analysis (TGA)
光伏组件用乙烯-醋酸乙烯共聚物中醋酸乙烯酯含量测试方法 热重分析法（TGA）
Application Summary AI generated
This standard specifies a thermal gravimetric analysis (TGA) method for measuring the vinyl acetate (VA) content in ethylene-vinyl acetate (EVA) copolymer films used in photovoltaic modules. It is applied by solar panel manufacturers and quality testing laboratories to verify the VA content of EVA encapsulant materials, which directly affects the module's optical transmission, cross-linking behavior, and long-term durability. The test ensures consistent material properties for reliable photovoltaic module production and performance validation.
