IEC\u00a060404-9:2018 specifies the measurement and test methods for the determination of the following geometrical characteristics of electrical steel strip and sheet:
\n\u2013\u00a0\u00a0\u00a0 edge wave (wave factor);
\n\u2013\u00a0\u00a0\u00a0 residual curvature;
\n\u2013\u00a0\u00a0\u00a0 edge camber;
\n\u2013\u00a0\u00a0\u00a0 deviation from the shearing line (internal stress);
\n\u2013\u00a0\u00a0\u00a0 burr height.
\nThis 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\u00a060404-1.
\nThis edition includes the following significant technical changes with respect to the previous edition:
\na. revision of terms and definitions;
\nb. specification of the length of test specimens for the determinations of edge wave (wave factor) and edge camber;
\nc. addition of the horizontal method for the determination of residual curvature, and a note that informs about a safety concern of the vertical method;
\nd. clarification that the burr height was characterized by the maximum value;
\ne. addition of the measuring procedure using a hand-held micrometer to determine the burr height.<\/p>\n","protected":false},"excerpt":{"rendered":"
