International standardization for wires and magnetic components

A large number of mechanisms and technologies are used in the modern world. Introducing more global systems into the technical support of an organization, one should not forget that the clarity and structure of the process being carried out fully depends on how well certain parts of the overall system function. Thus, it can be said that the regulation and tracking of the use of each part is an important aspect in production processes. Today we will talk about the international regulation of the use of wires and magnetic components.

Specifications for particular types of winding wires - Part 0–2: General requirements - Enamelled rectangular copper wire

Ferrite cores - Guidelines on dimensions and the limits of surface irregularities - Part 1: General specification

EN IEC 63093–1:2020

The division of standards into general characteristics and detailed regulation makes it possible to build a well-established system that will comply with all international norms and market rules. One such document is IEC 63093–1: 2020.

This standard specifies the dimensions and allowable limits of surface irregularities of ferrite cores. It is intended that this document excludes ferrite cores which are specialty cores with limited use. Also, special cores which are only marginal variations upon standard cores are excluded. IEC publishes electrical standards for families of ferrite cores, as well as this series of dimensional standards for families of ferrite cores. Modifications to the ferrite cores listed in one type of standard are reflected in the other type. This document is considered as a general specification useful in the dialogue between ferrite core suppliers and users about surface irregularities. This first edition cancels and replaces the second edition of IEC 60424–1 published in 2015 and the first edition of IEC 62317–1 published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous editions of IEC 60424–1 and IEC 62317–1: a) this document integrates IEC 60424–1 and IEC 62317–1.

Ferrite cores - Guidelines on dimensions and the limits of surface irregularities - Part 9: Planar cores

EN IEC 63093–9:2020

Sometimes individual parts of documents govern different stages and different characteristics of parts and technologies. One example is IEC 63093–9: 2020.

This standard specifies the shapes and dimensions of ferrite cores for inductive components (transformers and chokes), whose the coil is typically made of multi-layer boards (or the coil is part of the motherboard), and the effective parameter values used in calculations. This document gives guidelines on allowable limits of surface irregularities applicable to planar-cores as well. This document is considered as a sectional specification useful in the negotiation between ferrite core suppliers and users about surface irregularities. 

This first edition cancels and replaces the first edition of IEC 60424–5 published in 2009 and first edition of IEC 62317–9 published in 2006 and its Amendment 1:2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous editions of IEC 60424–5 and IEC 62317–9: a) IEC 63093–9 integrates IEC 60424–5 and IEC 62317–9; b) Table 1, Table 2 and Table 3 in IEC 60424–5:2009 have been moved to Annex B; c) some numbers are corrected in Table 4; d) Table 6 is amended following IEC 60205.

In order to more clearly understand which part of the standard is most suitable for you, read the detailed characteristics of the document and harmonize it with the requirements of your field of activity.

Magnetic powder cores - Guidelines on dimensions and the limits of surface irregularities - Part 1: General specification

EN IEC 63182–1:2020

Magnetic elements and parts are the simplest mechanism subject to the laws of nature. But this is only separate. If we talk about their application in production, then it should be noted that this mechanism is becoming more difficult and complex and that is why they are regulated by international standards, one of which will be discussed further.

IEC 63182–1:202 (E) specifies the dimensions of magnetic powder cores. 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. 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.

If you use the above technologies in your production or come into contact with them due to the activities carried out, we recommend that you familiarize yourself with this standard in order to understand the requirements of international markets and take a leading position in the implementation of activities on them.

Test method for the mechanical strength of cores made of magnetic oxides

EN IEC 61631:2020

Despite the fact that the test methods were originally created to further minimize risks, even they are regulated by international standards. Since the test methods are one of the first and fundamental stages in the use of technologies for their further launch, a lot of attention is paid to their international standardization and the creation of regulatory legal acts. One of the documents governing test methods in the use of magnetic devices is IEC 61631: 2020.

This standard is available as IEC 61631:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 61631:2020 specifies a test method for the mechanical strength of cores made of magnetic oxides. This test method is suitable for most of the E-cores, ETD-cores, I-cores and ring-cores but other core types such as U-cores could be tested according to a derived method agreed by the parties concerned. This document is also applicable to the mechanical strength measurement of magnetic powder cores. This edition includes the following significant technical changes with respect to the previous edition: - the phrase: "This document is also applicable to the mechanical strength measurement of magnetic powder cores" has been added in the scope; - IEC 61246 has been replaced by IEC 63093–8; EN 1002–2 has been replaced by ISO 7500–1; ISO 4677–1 and ISO 4677–2 have been withdrawn; - dimensions D and F in Figure A.1 and Table A.1 have been changed to be consistent with Figure 1 of IEC 63093–8:2018; - addition of the content of ring-cores test; - addition of Annex B; - the location of the jig is amended in Figure 3; - in Figure 5, the roller bars are moved to the edge of the I-core, aligned with the core.

Since the test methods are quite narrow-profile and specialized in each production, we recommend that you clarify the technical characteristics in more detail before purchasing the standard.

Terms and nomenclature for cores made of magnetically soft ferrites - Part 1: Terms used for physical irregularities and reference of dimensions

EN IEC 60401–1:2020

Since the number of technologies used is increasing every day, therefore, the variety of materials introduced into the process is increasing. The concept of "international market" has already become commonplace, and that is why regulation at the supranational level is necessary for the smooth functioning of the current system. One of the documents that regulates the use of magnetic products at this level is IEC 60401–1: 2020.

The standard is available as IEC 60401–1:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 60401–1:2020 provides a nomenclature of the most frequent surface, bulk and shape irregularities relevant to cores made of soft ferrites (magnetic oxides). Most irregularities are graphically exemplified as visual aids. A general recommendation is also given in Annex A for a consistent scheme for specifying the exact location of the irregularity, combining a general name for the location with more detailed qualifiers of the specified location. This document can also be useful as a terminology reference when preparing technical documentation, irregularity inspection specifications, etc. This document also presents a method for defining the designation nomenclature for the major physical attributes of soft ferrite core shapes. 

The purpose of this document is to facilitate uniform usage of dimensional characters by manufacturers, specifiers, and users when describing core dimensions on drawings, in tables, and on catalogue specification sheets. This second edition cancels and replaces the first edition of IEC 60401–1 published in 2002 and the second edition of IEC 60401–2 published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous editions of IEC 60401–1 and IEC 60401–2: - added the surface irregularity term "pores" in 4.3.1.6; - added the surface irregularity term "scratch" in 4.3.6.3; - removed the surface irregularity term "crater" in 4.1.5 of IEC 60401–1: 2002; - removed the bulk irregularity terms "superpores" in 5.1, "inclusions" in 5.2, "internal stratification" in 5.3 and "internal crack" in 5.4 of IEC 60401–1: 2002; - removed the contents related to "yoke ring cores" in 7.1.3 and 7.4 of IEC 60401–1:2002; - replaced the surface irregularity term "stratification" with "lamination" in 4.3.4.7; - replaced the location related terms "upper surface of back" with "bottom surface" and "lower surface of back" with "back surface" in Figure A.1; - changed Clause 7 of IEC 60401–1:2002 into Annex A.

It is this document that contains very detailed characteristics of the scope of possible application and parameters. Before purchasing this document, we recommend that you more clearly check the technical parameters of your organization and those specified in the standard.
