Full Description

IEC 60404-9 Ed. 2.0 b:2018 specifies the measurement and test methods for the determination ofthe following geometrical characteristics of electrical steel strip and sheet: edge wave (wave factor); residual curvature; edge camber; deviation from the shearing line (internal stress); burr height.This document applies to electrical steel strip and sheet intended for the construction ofmagnetic circuits and corresponding to Classes B2, C21, C22 and C23 of IEC 60404-1.
