适用范围:1.1 Domeniu de aplicarePrezenta porte a CEI 404 are scopul de a stabili metodele de m?surare a induc?iei magnetice, a polariza?iei magnetice ?i a intensit??ii c?mpului magnetic precum ?i determinarea curbei de demagnetizare ?i a dreptei de revenire a materialelor magnetic dure pentru magne?i permanen?i a?a cum sunt specificate ?n CEI 404-8-1, propriet??i ce se presupun a fi omogene ?n ?ntreg volumul.Caracteristicile unui sistem magnetic sunt dependente nu numai de propriet??ile materialului magnetic permanent, ci ?i de dimensiunile sistemului, ale ?ntrefierului, precum ?i de propriet??ile altor elemente ale circuitului magnetic. Metodele descrise ?n acest standard se refer? la m?surarea propriet??ilor magnetice ?n circuit magnetic ?nchis, care simuleaz? un tor.1.2 Referin?e normativeUrm?toarele documente normative con?in prescrip?ii care, ?mpreun? cu referin?ele din acest text, constituie prescrip?ii ale acestei p?r?i a CEI 404.
