标准摘要
[中文适用范围]： 本部分 IEC TS 62788 提供了测量光伏（PV）模块层压板内大多数界面粘附能的方法。与一般使用的其他粘附测试相比，该方法通过临界能量释放率提供粘附能的测量，因此更适用于比较不同试样类型的粘附性；例如不同材料、模块或样品，或应力暴露前后的材料。这是一种“最弱环节”测试，意味着在给定测试中最有可能失效的是最弱的界面。如果系统中存在较弱的界面，则可能难以有意测量特定层的粘附性。 [外文原描述]： IEC TS 62788-6-3:2022 describes the single cantilevered beam (SCB) test, useful for characterizing adhesion in photovoltaic (PV) modules. This document offers a generalized method for performing the test, with the expectation that best practices for utilizing this test method will be developed for specific applications. This document provides a method for measuring the adhesion energy of most interfaces within the photovoltaic (PV) module laminate. This method provides a measure of adhesive energy, via the critical energy release rate, and so is more useful for comparing adhesion of different specimen types; e.g. different materials, module or coupon samples, or materials before and after stress exposure.
