Measurement procedures for materials used in photovoltaic modules - Part 6-3: Adhesion testing for PV module laminates using the single cantilevered beam (SCB) method

Scope

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.
