IEC 62317-11:2015 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of EC-cores, the essential dimensions of coil formers to be used with them, and the effective parameter values to be used in calculations involving them. This first edition cancels and replaces the first edition of IEC 60647 published in 1979. This edition constitutes a technical revision and includes the following significant technical changes with respect to the first edition of IEC 60647:
- addition of EC90 and EC120 cores in Table 1,
- addition of effective parameter and A<sub>min</sub> values and main dimensions of coil formers for EC90 and EC120 cores.
