Annotation of standard text IEC 62358-ed.3.0 :

IEC 62358:2026 provides standard AL values (inductance factors) and their tolerances of Pot, RM, ETD, E, EER, EP, PQ, PM, EC, EFD and low-profile gapped ferrite cores. This edition includes the following significant technical changes with respect to the previous edition: a) addition of AL value (inductance factor) and its tolerance for PM-cores; b) addition of AL value (inductance factor) and its tolerance for EC-cores; c) addition of AL value (inductance factor) and its tolerance for EFD-cores.
