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
Describes the dimensions that are of importance for mechanical interchangeability for a preferred range of square cores (RM-cores) made of magnetic oxides, the dimensional limits for wound coil formers to be used with these cores and the locations of their terminal pins on a 2.54 mm printed wiring grid in relation to the base outlines of the cores.
