IEC TS 62607-6-26:2025 PDF

IEC TS 62607-6-26:2025, which is a Technical Specification, establishes a standardized method to determine the mechanical key control characteristics (KCCs) • Young's modulus (or elastic modulus), • residual strain, • residual stress, and • fracture stress of 2D materials and nanoscale films using the • bulge test. The bulge test is a reliable method where a pressure differential is applied to a freestanding film, and the resulting deformation is measured to derive the mechanical properties. • This method is applicable to a wide range of freestanding 2D materials, such as graphene, and nanometre-thick films with thicknesses typically ranging from 1 nm to several hundred nanometres. • This document ensures the characterization of mechanical properties essential for assessing the structural integrity and performance of materials in applications such as composite additives, flexible electronics, and energy harvesting devices.
