Anotation

IEC 60404-5:2015 is to define the method of measurement of the magnetic flux density, magnetic polarization and the magnetic field strength and also to determine the demagnetization curve and recoil line of permanent magnet materials. This edition includes the following significant technical changes with respect to the previous edition: - adaption of the measurement methods and test conditions to newly introduced magnetically hard materials with coercivity values HcJ higher than 2 MA/m; - update of the temperature conditions to allow the measurement of new materials with high temperature coefficients. LIEC 60404-5:2015 a pour objectif de definir la methode de mesure de linduction magnetique, de la polarisation magnetique et lintensite du champ magnetique, mais aussi de determiner la courbe de desaimantation et la droite de recul des materiaux pour aimants permanents. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: - adaptation des methodes de mesure et des conditions dessai aux materiaux magnetiquement durs recemment introduits possedant un champ coercitif HcJ superieur a 2 MA/m; - mise a jour des conditions de temperature, afin de permettre la mesure de nouveaux materiaux avec des coefficients de temperature eleves.
