Magnetic powder cores - guidelines on dimensions and the limits of surface irregularities - Part 4: Block-cores

This part of IEC 63182 specifies the preferred range of the dimensions that are important for mechanical interchangeability and the guidelines on allowable limits of surface irregularities for block-cores made of metallic magnetic powder.
This document is a specification about surface irregularities which is useful in the negotiations between suppliers and users of magnetic powder core.
The use of "derived" standards which give more detailed specifications of component parts while still permitting compliance with this standard is discussed in Annex A.

Magnetpulverkerne – Richtlinien zu Maßen und Grenzen von Oberflächenbeschädigungen – Teil 4: Blockkerne

Noyaux en poudre magnétique - Lignes directrices concernant les dimensions et les limites des irrégularités de surface - Partie 4: Noyaux en blocs

L’IEC 63182-4:2021 spécifie la plage préférentielle des dimensions qui sont importantes pour l’interchangeabilité mécanique, ainsi que les lignes directrices concernant les limites admissibles des irrégularités de surface pour les noyaux en blocs en poudre magnétique métallique. Le présent document est une spécification portant sur les irrégularités de surface, qui est utile pour les négociations entre les fournisseurs et les utilisateurs de noyaux en poudre magnétique.

Jedra iz magnetnega prahu - Smernice o merah in mejnih vrednostih površinskih nepravilnosti - 4. del: Blokovna jedra

Ta del standarda IEC 63182 določa prednostni razpon mer, ki so pomembne za mehansko medsebojno zamenljivost, in smernice o dovoljenih mejnih vrednostih površinskih nepravilnosti za blokovna jedra, izdelana iz kovinskega magnetnega prahu.
Ta dokument je specifikacija o površinskih nepravilnostih, ki je uporabna za sklepanje dogovorov med dobavitelji in uporabniki jeder iz magnetnega prahu.
Uporaba »izpeljanih« standardov, ki podajajo podrobnejše specifikacije o delih komponent in hkrati dovoljujejo skladnost s tem standardom, je obravnavana v dodatku A.

27 FOREWORD

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

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

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

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

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

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

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

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

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

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

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

39 interested IEC National Committees.

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

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

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

43 misinterpretation by any end user.

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

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

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

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

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

49 services carried out by independent certification bodies.

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

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

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

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

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

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

56 indispensable for the correct application of this publication.

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

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