(Main)Magnetic materials - Methods of determination of the geometrical characteristics of electrical steel sheet and strip
Magnetic materials - Methods of determination of the geometrical characteristics of electrical steel sheet and strip
This European Standard is intended to define the test methods used for the determination of the following geometrical characteristics of electrical steel sheet and strip:
— edge wave (wave factor);
— residual curvature;
— edge camber;
— deviation from the shearing line due to internal stresses;
— burr height of cut edges.
This European Standard applies to electrical steel sheet and strip intended for the construction of magnetic circuits and corresponding to Clauses B2, C21 and C22 of IEC 60404-1:2000.
Magnetische Werkstoffe - Verfahren zur Bestimmung der geometrischen Kenngrößen von Elektroblech und -band
Dieses Dokument soll die Verfahren festlegen, nach denen die folgenden geometrischen Kenngrößen von Elektroblech und –band zu bestimmen sind:
— Kantenwelligkeit;
— Bogigkeit;
— Kantenkrümmung;
— Abweichung von der Schnittlinie aufgrund innerer Spannungen;
— Grathöhe von Schnittkanten.
Dieses Dokument gilt für Elektroblech und –band, das zum Aufbau magnetischer Kreise und entsprechend den Abschnitten B2, C21 und C22 der EN 60404-1:2017 verwendet werden soll.
Matériaux magnétiques - Méthodes de détermination des caractéristiques géométrique des bandes et tôles en acier électrique
Le présent document a pour objet de définir les méthodes d’essai à utiliser pour la détermination des
caractéristiques géométriques suivantes des bandes et tôles en acier électrique :
— ondulation de rive ;
— courbure résiduelle ;
— rectitude ;
— déviation par rapport à la ligne de cisaillage due aux tensions internes ;
— hauteur de bavure des rives cisaillées.
Le présent document s’applique aux bandes et tôles en acier électrique destinées à la construction de
circuits magnétiques et correspondant aux Articles B2, C21 et C22 de l’EN 60404-1:2017.

This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 459/SC 8.
If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.
This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.
CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and
