GB/T 41203-2021 specifies accelerated aging test methods for encapsulation materials such as glass, encapsulant films, and backsheets used in photovoltaic modules, with other related encapsulation materials being referentially applicable. The standard includes two types of tests: high-pressure steam cooking and ultraviolet-high-temperature-high-humidity. It details requirements for sample preparation, environmental conditioning, and data processing. Core instruments used include aging test chambers, spectrometers, tensile testing machines, and colorimeters. By simulating harsh environments to accelerate material aging, the standard tests and calculates indicators such as transmittance retention rate, yellowing index, and peel strength to evaluate the weather resistance stability of materials. This provides a unified technical basis for the reliability design and quality control of photovoltaic modules.
