Lead Terminal Strength Tester
The Lead Terminal Strength Tester is designed to evaluate the adhesion strength of photovoltaic (PV) module lead terminals to the module body. By applying controlled tensile, torsional, and surface-fixed forces, it simulates mechanical stresses encountered during installation, transportation, and operation.
Standards
IEC 61215-2:2016 – Photovoltaic (PV) Module Design and Certification Standard
