Magnetic powder cores - Guidelines on dimensions and the limits of surface irregularities - Part1: General specification

This part of IEC 63182 specifies the dimensions of magnetic powder cores.
It is intended that this document will include magnetic powder cores which are widely used and
referenced in industry, either because they are included in national standards, or because they
are seen to have broad-based use in industry. Where applicable, it is intended that the existing
industrial name for each powder core will appear with the part within the IEC 63182 series.
This document also gives guidelines on the allowable limits of surface irregularities of magnetic
powder cores. It is considered as a general specification useful in the dialogue between
magnetic powder core manufacturers and users about surface irregularities.

Noyaux en poudre magnétique comprimée - Lignes directrices concernant les dimensions et les limites des irrégularités de surface - Partie 1: Spécification générale

L'IEC 63182-1:2020 spécifie les dimensions des noyaux en poudre magnétique. Le présent document spécifie également des lignes directrices concernant les limites admissibles des irrégularités de surface des noyaux en poudre magnétique. Il convient de considérer ces lignes directrices comme une spécification générale utile dans le dialogue entre les fabricants et les utilisateurs des noyaux en poudre magnétique portant sur les irrégularités de surface. Il est prévu que le présent document inclue les noyaux en poudre magnétique largement utilisés et référencés dans le secteur industriel, soit parce qu’ils sont inclus dans des normes nationales, soit du fait de leur emploi réputé généralisé dans ledit secteur. Le cas échéant, il convient que le nom industriel existant pour chaque noyau en poudre magnétique apparaisse avec la partie dans la série de normes IEC 63182.

FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their

preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

may participate in this preparatory work. International, governmental and non-governmental organizations liaising

with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence between

any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

rights. IEC shall not be held responsible for identifying any or all such patent rights.
