FOREWORD
PREFACE
1 Scope
2 Conversion system
3 Primary standards
4 Derived standards
5 Standard inductance measuring coils
APPENDIX A - Square coil design
APPENDIX B - Example of a standard for the main dimensions
             of coil formers for square cores (RM-cores)
             meeting the IEC primary standard
Annex ZA (normative) Normative references to international
         publications with their corresponding European
         publications

Defines important dimensions for mechanical interchangeability for a preferred range of square cores (RM-Cores) made from magnetic oxides, dimensional limits for wound coil formers for use with these cores and locations of their terminal pins on a 2.54 mm printed wiring grid relative to the base outlines of the cores. In addition, it defines the main parameters of a range of standard inductance measuring coils for test purposes.
