标准摘要
[中文适用范围]： 本文档规定了磁性材料中电气钢带和钢带的几何特性的测量和试验方法，包括：边缘波（波度因子）、残余曲率、边缘弯曲度、剪切线偏差（内应力）和毛刺高度。本文档适用于用于构建磁路的电气钢带和钢带，且符合IEC 60404-1中B2、C21、C22和C23类别的钢带和钢带。 [外文原描述]： IEC 60404-9:2018 specifies the measurement and test methods for the determination of the 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 of magnetic circuits and corresponding to Classes B2, C21, C22 and C23 of IEC 60404-1. This edition includes the following significant technical changes with respect to the previous edition: a. revision of terms and definitions; b. specification of the length of test specimens for the determinations of edge wave (wave factor) and edge camber; c. addition of the horizontal method for the determination of residual curvature, and a note that informs about a safety concern of the vertical method; d. clarification that the burr height was characterized by the maximum value; e. addition of the measuring procedure using a hand-held micrometer to determine the burr height.
