Overview
EN 60404-8-6:2017 (identical to IEC 60404-8-6:2016) is a European standard that specifies requirements for soft magnetic metallic materials. It covers general requirements, magnetic properties, geometric characteristics and tolerances, and inspection procedures for materials such as pure iron, silicon‑iron, nickel‑iron and cobalt‑iron in the forms of bar, billet, sheet, strip or wire. The alloys addressed correspond to classes A, C1, C2, E1–E4 and F1–F3 as defined in IEC 60404-1. A notable change in this edition is the removal of Table 2b).
Key topics and technical requirements
- Classification and designation of soft magnetic metallic materials in line with IEC 60404-1.
- Magnetic property requirements:
- DC and AC measurement procedures for permeability, coercivity and related magnetic parameters (referenced specimen types and test methods).
- AC measurements at power frequencies (50 Hz / 60 Hz) for sheet and strip.
- Geometric characteristics and tolerances:
- Thickness, width, flatness and edge camber for flat products (sheet/strip).
- Dimensional tolerances, straightness and surface condition for long products (bar, rod, wire).
- Specific dimensional requirements for toroidal strip-wound cores.

Applications and users
EN 60404-8-6:2017 is used to:
- Specify material acceptance criteria in procurement of soft magnetic materials.
- Guide quality assurance and laboratory testing for transformer cores, inductors, motors, relays, and other electromagnetic devices.
- Support material selection by electrical and mechanical designers who require defined magnetic performance and dimensional tolerances. Typical users include material suppliers, component manufacturers, test laboratories, procurement engineers, and product designers working with soft magnetic metallic alloys.

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.
International Standard IEC 60404-8-6 has been prepared by IEC technical committee 68:
Magnetic alloys and steels.
This third edition cancels and replaces the second edition published in 1999 and
Amendment 1:2007. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:

Soft magnetic metallic materials
1 Scope
This part of IEC 60404 specifies the general requirements, magnetic properties, geometric
characteristics and tolerances as well as inspection procedures for pure iron, silicon-iron,
nickel-iron and cobalt-iron. The materials are in the form of bar, billet, sheet, strip or wire. The
alloys covered correspond to those defined by classes A, C1, C2, E1 to E4 and F1 to F3 in
IEC 60404-1.
Magnetic materials used primarily for relays, iron and steel products, classified only by
coercivity, are covered in IEC 60404-8-10. IEC 60404-8-10 is less restrictive in terms of
magnetic properties than the irons (class A) and the silicon steels (classes C21 and C22)
specified in this standard, but it gives more comprehensive dimensional tolerances.
Non-oriented and oriented silicon steels (C21 and C22) for industrial power frequency
applications, classified by specific total loss, are covered in IEC 60404-8-3, IEC 60404-8-4
and IEC 60404-8-7.
Non-oriented and oriented thin magnetic materials for use at medium frequencies, classified
by specific total loss, are covered in IEC 60404-8-8.

この記事では、SIST EN 60404-8-6:2017における「磁性材料-第8-6部：個々の材料の仕様-軟磁性金属材料（IEC 60404-8-6:2016）」の仕様について取り上げています。この規格では、純鉄、シリコン鉄、ニッケル鉄、コバルト鉄の一般的な要件、磁気特性、ジオメトリ特性と許容差、検査手順が定められています。これらの材料はバー、ビレット、シート、ストリップ、ワイヤーなどの形状で提供されます。IEC 60404-1で定義されたAクラス、C1クラス、C2クラス、E1〜E4クラス、F1〜F3クラスに対応する合金がカバーされています。ただし、中継器、鉄および鋼製品に主に使用される磁性材料は磁気特性による分類に限定され、IEC 60404-8-10で取り上げられています。IEC 60404-8-10は、この規格で指定されている鉄（Aクラス）やシリコン鋼（C21およびC22クラス）よりも磁気特性については制約が少ないですが、寸法許容差に関してはより包括的です。工業用の電力周波数応用のための非方向性および方向性のシリコン鋼は、IEC 60404-8-3、IEC 60404-8-4、IEC 60404-8-7で扱われています。中周波数で使用するための非方向性および方向性の薄い磁性材料は、IEC 60404-8-8で扱われています。
이 기사는 SIST EN 60404-8-6:2017에 대한 내용을 다루고 있습니다. 이 기준은 연성 자성 금속 재료에 대한 일반 요구 사항, 자기 특성, 기하학적 특성 및 허용 오차, 검사 절차를 명시합니다. 이 요구 사항은 순철, 실리콘-철, 니켈-철, 코발트-철로 이루어진 막대, 빌렛, 시트, 스트립 또는 와이어 형태의 재료에 적용됩니다. 이 기준에 따른 합금은 IEC 60404-1에서 A, C1, C2, E1부터 E4, F1부터 F3 클래스로 정의됩니다. 리프레이, 철 및 강 제품에 사용되는 자기 재료는 IEC 60404-8-10에서 다루며, 이 기준은 이 기준에 기술된 순철(A 클래스)과 실리콘 강(C21 및 C22 클래스)보다 자기 특성에서는 덜 제한적이지만 기하학적 허용 오차에서는 보다 포괄적입니다. 패턴이 없거나 방향성이 있는 실리콘 강(C21 및 C22)은 IEC 60404-8-3, IEC 60404-8-4 및 IEC 60404-8-7에서 다루고, 중간 주파수 사용을 위한 패턴이 없거나 방향성이 있는 얇은 자기 재료는 IEC 60404-8-8에서 다룹니다.
The article discusses the specifications outlined in SIST EN 60404-8-6:2017 for soft magnetic metallic materials. The standard covers pure iron, silicon-iron, nickel-iron, and cobalt-iron in various forms such as bar, billet, sheet, strip, or wire. These materials fall into classes A, C1, C2, E1 to E4, and F1 to F3 as defined in IEC 60404-1. However, materials used for relays, iron and steel products, and classified only by coercivity are covered in IEC 60404-8-10, which has less restrictive magnetic properties but more comprehensive dimensional tolerances. Non-oriented and oriented silicon steels for industrial power frequency applications are covered in other standards (IEC 60404-8-3, IEC 60404-8-4, and IEC 60404-8-7), while non-oriented and oriented thin magnetic materials for medium frequency use are covered in IEC 60404-8-8.
