1. About IEC publications
An IEC reference number for a publication is composed of a header plus three elements: 1) the publication number, 2) the part number and 3) the section number.
As from 1997 all new IEC publications and parts, as well as new editions, revisions and amendments are being issued with a designation in the 60000 series, however this does not affect the content. It is now necessary to add 60000 to the existing base number.
Example: IEC 529 is now referenced as IEC 60529.
The 80000 series is allocated to multipart standards jointly developed by IEC and ISO in some exceptional cases, in which some parts are published by ISO and others by IEC. The use of the ISO/IEC prefix is strictly limited to ISO/IEC JTC1 publications as well as some ISO/IEC guides.
IEC publications are bilingual (English/French) or monolingual, some versions are derived from the bilingual publication by deleting the French-language or English-language pages as appropriate. Most publications are also available in Spanish and some in Russian.
The following letter codes denote the available language(s) for each publication:
The International Electrotechnical Commission is the leading global organization that publishes consensus-based international standards and manages conformity assessment systems for electric and electronic products, systems and services, collectively known as electrotechnology.
The IEC develops different types of publications:
- international standard (IS)
- technical specification (TS)
- technical report (TR)
- publicly available specification (PAS)
- systems reference deliverable (SRD)
- technology report (TEC)
- white paper (WP)
For more information click here.
For IEC Conformity Assessment we have:
- conformity assessment (CA)
- component specification (CS)
- operational document (OD)
- test report form (TRF)
You will find below categories of technical questions and who to contact:
Please contact the secretary of the IEC National Committee in your country.
Error in the publication
Please contact us.
If your questions do not fall into any of these categories, please contact us.
The IEC Central Office has introduced “Series packages” for a limited selection of bestselling standards. Each package includes all parts of the series and amendments where needed.
A 15% discount of the total catalogue price is included.
You will find here the list of series available.
The IEC publishes consolidated versions of its publications with all the amendments included in the base document.
|Edition 1.0||base document without any amendments|
|Edition 1.1||base 1.0 edition consolidated with one amendment|
|Edition 1.2||base 1.0 edition consolidated with two amendments|
|Edition 2.0||second edition of a base document.
This may include new information combined as well as amendments from edition 1.x.
|Edition 2.1||second edition consolidated with one amendment|
Since May 2010, additions and deletions are displayed in red, with deletions being struck through in all new consolidated versions. Since May 2012, the release of the consolidated version is strictly synchronized with that of the amendment.
I have edition 1.2, do I have to buy amendments?There is no need to buy the amendments because they are already included in the consolidated version.
If you have the base edition (1.0, 2.0, 3.0,…) of a standard, you may purchase amendments separately.
A technical corrigendum is issued to correct either:
- A technical error or ambiguity in an International Standard, a Technical Specification, a Publicly Available Specification or a Technical Report, inadvertently introduced either in drafting or in printing and which could lead to incorrect or unsafe application of the publication, or
- Information that has become outdated since publication, provided that the modification has no effect on the technical normative elements of the standard.
Once published corrigenda are immediately integrated in the corresponding publication. They are also available separately and can be freely downloaded here.
Electropedia contains all the terms and definitions in the International Electrotechnical Vocabulary or IEV which is published also as a set of publications in the IEC 60050 series that can be ordered separately from the IEC Webstore.
Electropedia is the world's most comprehensive online electrical and electronic terminology database containing more than 20 000 terms and definitions in English and French organized by subject area, with equivalent terms in various other languages: Arabic, Chinese, Czech, Finnish, German, Italian, Japanese, Norwegian (Bokmål and Nynorsk), Polish, Portuguese, Russian, Serbian, Slovenian, Spanish and Swedish (coverage varies by subject area).
An interpretation sheet provides a quick formal explanation to an urgent request by a user of a standard (testing laboratory, manufacturer, etc.). Changes of requirements or test procedures in a standard by means of an interpretation sheet shall be avoided. It is recognized that it is sometimes difficult to define what is a "matter of interpretation" for a given standard.
For more information please refer to ISO/IEC Directives.
All the Interpretation sheets can be freely downloaded here.
IEC Publications are generally available in paper and PDF electronic format, but the ones with over 300 pages are provided on CD instead of paper.
On our Webstore, you can find out the document format available for publications of your choice.
The following format symbols are used on our Webstore:
|Portable Document Format (Adobe Acrobat Reader)|
|CD / DVD / Blu-ray ™|
|Ebooks (PDF, ePub)|
|Word (only for TRF)|
For customers wishing to purchase a large quantity of standards we can deliver on CD.
A Redline version contains both the current IEC standard and a Redline version of the document which shows changes from the previous edition marked in colour. With the Redline you can quickly spot changed sections and tell specifically what has been changed from the previous edition, saving time and avoiding confusion.
The development of a Redline version is not systematic. Criteria are the popularity of the Publication and the clear structure of the changes. If the changes are too much interwoven into the content, a Redline version may be unreadable and thus, lose the benefit of a clear and quick identification of the changes.

Commented version is the only product where the consensus-based content of a publication is enriched with technical information. It is made of a redline version with highlighted areas where technical committee experts provide the reasons and rationale of the most relevant changes. The summary of comments is also provided at the end of the document.
With commented versions, users can better understand the rationale for changes made to the newest edition of the standard. Comments include an explanation for the changes as well as information on the impact of these changes on the application and usability of the standard.
Commented versions are an enhanced version of the traditional IEC Redline Version (RLV) which highlights the changes between the previous edition and the new edition.
This value-added product consist of a package, which includes both the new edition of the publication, and the commented redline version.

We currently have the following:
IEC 61204-7:2016 EXV which includes the provisions of the general rules dealt with in IEC 62477-1:2012.
The Extended version is not an official IEC Standard. Only the current versions of the related standards are to be considered the official documents.
IEC 62040-1:2017 EXV which includes the provisions of the general rules dealt with in IEC 62477-1:2012.
The Extended version is not an official IEC Standard. Only the current versions of the related standards are to be considered the official documents.
The development process for IEC standards follows defined stages. The stage codes used by IEC are based on the international harmonized stage code system.You can find the list of stage codes at the following address.
Systems Reference Deliverable (SRD) is a deliverable produced by Systems Committees only. A SRD is a guidance document on the use and application of specific standards in the SyC domain. A SRD can be a normative document. SyCs may produce multiple SRDs that address, but are not limited to:
A Test Report Form (TRF) is a document prepared by a National Certification Body (NCB) allowing a test laboratory to record the evidences and the results of the tests and analysis made on a product. Its primary intent is to support the emission of a Certification Body Certificate.
Made available for all the community, a TRF represents the “State of the Art”. All the required information to document a test or analysis are included in the TRF and its use is ease by a common structure fully aligned with the structure of the IEC or ISO standard.
What is the added value for customers ?“Save time and money and promote your know-how by using TRF” !
When buying a TRF, you don’t need to “re-invent the wheel”. Developed by the Certifications Bodies engaged in the IECEE, they represent the “State of the Art”. All the required information to document a test or analysis are included in the TRF and its use is ease by a common structure fully aligned with the structure of the IEC or ISO standard. No need to spend days to create your own forms, with the risk to forget something. These TRF will save your time and your money.
Why they are only in English version ?As its main intent is to evidence of compliance to the customers, certification body, regulators and all other stakeholders on the market, it has to be understood by all. It’s why the TRF are issued only in English language, which is the most common language used by technical people.
How are these documents updated ?The issuance and the update of a given TRF is done and managed by one dedicated Certification Body of the IECEE, following the guidance provided in the document OD-2020.
Does it exist a TRF for each IEC standard ?Close to 2'000 TRF are available, they focus mainly on electrical safety standards.
How the customers can use a TRF ?The publication may be reproduced in whole or in part for non-commercial purposes as long as the IECEE is acknowledged as copyright owner and source of the material. IECEE takes no responsibility for and will not assume liability for damages resulting from the reader's interpretation of the reproduced material due to its placement and context.
2. Search and find publications
The search results mention a Stability date for some publications. The contents of the publications will remain unchanged up to the Stability date. At this date, the publication will be either reconfirmed, withdrawn, replaced by a revised edition or amended. If there is a revision or amendment on-going then this is mentioned under the publication in the “Work in progress” tab, if you don't see this tab it means that there is no project under development.
Stability periods are based on an assessment of the maturity of the technology and future, foreseen changes due to development or maintenance of associated publications. Typically stability periods are between 3 and 12 years. If a committee needs to process an amendment or revision before the review date, it may decide to advance the review date and modify the stability date accordingly.
Several publications are available in database format. You will find the complete list here

You can cost-effectively share electronic versions of IEC publications on your company or organization's computer network. Simply multiply the price of the IEC publication according to the relevant factor. Choose between multiple workstations and networking with simultaneous users.
What are your rights? You can preview a copy of the licence here.
- The publication is stored on an internal network and its access is monitored to limit the access to the chosen number of simultaneous users.
- It is permitted to make hard copies of each publication, up to the specified number of users.
- Example for a simultaneous licence for up to 5 users: any 5 users at a time may access the publication, you may print up to 5 copies of the publication.
Networking with simultaneous users
|No. of users requiring access to the publications||Networking factor|
|Up to and including 3 users||2.5|
|Up to and including 5 users||3.0|
|Up to and including 10 users||3.5|
|Up to and including 15 users||4.0|
|Up to and including 20 users||4.5|
|Above 20 users||Please contact the Customer Service Centre|
For example IEC 61508-1 has a price of CHF 310.-. For up to and including 5 users, the price would be 310.- x 3 = CHF 930.- (the equivalent of CHF 186.- per user).
- The publication has to be stored on a fixed number of workstations.
- It is permitted to make hard copies of each publication, up to the specified number of workstations.
- Example for a workstation licence for up to 3 workstations: the publication can be stored on a maximum of 3 different workstations, you may print up to 3 copies of the publication.
|No. of workstations having access to the publications||Multiplying factor|
|Up to and including 3 workstations||1.5|
|Up to and including 5 workstations||2.0|
|Up to and including 10 workstations||2.3|
|Up to and including 15 workstations||2.8|
|Up to and including 20 workstations||3.2|
|Above 20 workstations||Please contact the Customer Service Centre|
For example IEC 61508-1 has a price of CHF 310.-.
For up to and including 5 workstations, the price would be 310.- x 2 = CHF 620.- (the equivalent of CHF 124.- per workstation).
To purchase a multiple workstation licence please contact the Customer Service Centre, specifying what publications you are interested in and for how many workstation they would be for.

The IEC Central Office cannot sell or send out working documents because they are still in the project stage and modifications may overcome.
We also suggest you to contact the IEC National Committee in your country, who may be able to give you the information on the projects.
The corporate account facility has been designed for companies who regularly purchase standards on the IEC Webstore. It is therefore not meant for one off purchases.
To benefit from this service you pay in advance either by credit card or bank transfer a minimum of CHF 2'000.- and you get an extra credit of 15% on the amount paid. Upon payment you receive a login and password allowing you to download IEC publications on our website. All the costs of your future orders will be automatically deducted from your account.
For example if you pay CHF 2’000.- you will be able to download up to CHF 2’300.- worth of publications. You can then place several orders for as many publications as you require, as long as the total does not exceed the credit limit. The system does not allow you to place an order if the publication price exceeds the remaining credit in your account.
You will receive an invoice receipt when your corporate account is set up, and a statement of account on a monthly basis that lists all the orders placed through our Webstore and shows the balance remaining on your account.

I have two publications with the same number but one is IEC and the other BS EN. What is the difference?
Other entities and/or organizations can adopt IEC standards to which they have the possibility of adding changes. However, we are not necessarily informed of those changes/modifications. Please therefore contact the organisation that has published the standard in question.
The IEC runs four conformity assessment systems, each of which operates schemes based on third-party conformity assessment certification. Together they establish that a product is reliable and meets expectations in terms of performance, safety, efficiency, durability and other criteria.
IECEE: IEC System of Conformity Assessment Schemes for Electrotechnical Equipment and Components.
IECEx: IEC System for Certification to Standards relating to Equipment for use in Explosive Atmospheres.
IECQ: IEC Quality Assessment System for Electronic Components.
IECRE: IEC System for Certification to Standards Relating to Equipment for Use in Renewable Energy Applications
If you have questions, you will need to choose the right conformity assessment scheme for your products. Please click here for more information.
We are the Central Office of the International Electrotechnical Commission (IEC) that prepares and publishes international standards for all electrical, electronic and related technologies.
Although some 90% of European standards are identical or very closely based on IEC international standards, if you are interested in a specific EN reference or other European standards, you should contact CENELEC (European Committee for Electrotechnical Standardization).
You don't need to be an IEC member to purchase IEC standards, you can place an order directly on our Webstore.
IEC membership is only open to countries and not to regional organizations, companies or individuals. An IEC member is called a National Committee and each NC represents its nation's electrotechnical interests in IEC management and standardization work.
If you wish to participate in the development and elaboration of IEC standards, please get in touch with the IEC National Member Body in your country, who will give you further information. Please click here to get the contact details.
Please also check the related information.
The ISO/IEC Guide 21-1 provides the methods for adoption of IEC International Standards as regional or national standards and includes a system for indicating the degree of correspondence so as to promote coherence in the way regional or national standards bodies adopt international standards and indicate the degree of correspondence with international standards. It applies equally to the adoption of other international normative and informative documents such as technical reports. Greater uniformity in the indication of both correspondence and deviations among countries will aid communication, avoid confusion and facilitate trade.
You cannot use the IEC logo as a mark to confirm that your product follow our standards. You should use the certification body logo instead (SGS, TUV,...).
Our attention has been drawn to a number of references “IEC 61216” being used in the solar photovoltaics (PV) industry, more particularly in the field of certification.
IEC Central Office wishes to make clear that it has never issued an international standard (or any other publication) under the reference “IEC 61216”, neither in the PV field, nor in any other field.
The standard to be used in the field of solar photovoltaics is IEC 61215: 2005, Crystalline silicon terrestrial photovoltaic (PV) modules - Design qualification and type approval.
IEC 61215 is being revised; in its new edition (expected to be published in 2016) it will be available as a series of standards, under references IEC 61215-1, IEC 61215-1-1, IEC 61215-1-2, IEC 61215-1-3, IEC 61215-1-4, IEC 61215-2.
To help bring electrical energy to some of the 1,3 billion people without access or with only limited energy access, the IEC, World Bank Group and United Nations Foundation have a cooperative agreement to provide developing countries with access to important technical documents that support rural electrification, at a specially discounted price.
The IEC Technical Specification 62257 series Recommendations for small renewable energy and hybrid systems for rural electrification outlines international best practice solutions to support energy access in developing countries across a range of technologies. The three organizations are cooperating to offer discounts to qualified stakeholders purchasing documents in the IEC TS 62257 series.
The IEC 62257 series contains numerous technical specifications which address three main topics – introduction to rural electrification; project management and implementation guidelines; and technical specifications for components and systems. The IEC TS 62257 series also provides assistance to the project implementer, with information on how to select the right product based on what is available in their local market, product tests to be performed under the local future field conditions, and technical and economic aspects of equipment, skills required etc.
The details of the available discounts are:
75 % discount on IEC TS 62257-9-5 (with or without all normative references)
75 % discount on IEC TS 62257-9-8 (with or without all normative references)
58% discount on entire IEC TS 62257 series + all normative references
or 50% discount on any individual documents in the IEC TS 62257 series
