Magnetic materials - Method of measurement of the coercivity of magnetic materials in an open circuit
This European standard specifies the method of measurement of the coercivity of magnetic materials in an open magnetic circuit.
It applies to magnetic materials having a coercivity up to 500 kA/m. Special precautions to take in measuring coercivities below 40 A/m and above 160 kA/m are given in annex A.
Magnetische Werkstoffe - Verfahren zur Messung der Koerzivität magnetischer Werkstoffe im offenen Magnetkreis
Diese Europäische Norm legt das Verfahren zur Messung der Koerzivität magnetischer Werkstoffe in einem offenen Magnetkreis fest.
Die Norm gilt für magnetische Werkstoffe mit einer Koerzivität bis 500 kA/m. Besondere Vorkehrungen müssen bei Messungen von Koerzivitäten unter 40 A/m und über 160 kA/m getroffen werden, siehe Anhang A.
Matériaux magnétiques - Méthode de mesure du champ coercitif des matériaux magnétiques en circuit magnétique ouvert
La présente Norme européenne spécifie la méthode de mesure du champ coercitif des matériaux magnétiques dans un circuit magnétique ouvert.
Elle s'applique aux matériaux magnétiques possédant un champ coercitif inférieur ou égal a 500 kA/m. Les précautions particulieres a prendre dans le cas des champs coercitifs inférieurs a 40 A/m et supérieurs a 160 kA/m sont données dans l'annexe A.
