Abstract
Overview
ISO 11531:2022 - Metallic materials - Sheet and strip - Earing test specifies a standardized method to determine ear height in metal sheet and strip (nominal thickness 0.1 mm to 3 mm) after deep drawing. The earing test evaluates the tendency of drawn cylindrical cups to develop uneven rim heights ("ears") that reflect anisotropy and material properties. The standard defines test principle, equipment, test pieces, procedure, result interpretation and reporting requirements for reproducible measurement of ear formation.
