Technical Reports (TR)
Publicly Available Specifications
Limited consensus products
Industry Technical Agreements (ITAs)
Technology Trend Assessments (TTAs)
For more information click here.
|How does your numbering system work?|
|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.
|Which publication formats are available?|
|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:
For customers wishing to purchase a large quantity of standards we can deliver on CD.
|In which languages are your publications available?|
|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. |
The following letter codes denote the available language(s) for each publication:
|What is a consolidated edition?|
|The IEC publishes consolidated editions of its publications with all the amendments and corrigenda included in the base document.|
Since May 2010, additions and deletions are displayed in red, with deletions being struck through in all new consolidated versions.
Amendment: a normative document developed according to consensus procedures. It changes the technical normative elements of a particular international standard.
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 edition.
But if you have a base edition (1.0, 2.0, 3.0,…) in such case it is recommended that you obtain amendments if available.
|What are the series collection?|
|To better serve the needs of IEC customers, the Central Office has introduced "Series Packages" for a limited selection of best selling standards. Each package includes all parts of the series and amendments where needed.|
To encourage the sale of the packages they will be priced at a 15% discount of the total catalogue price.
You will find here the list of standards included in each package.
|What is a Redline ?|
|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 color. With the Redline you can quickly spot changed sections and tell specifically what has been changed from the previous edition, saving time and 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.
|Where can I find corrigenda?|
|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.
|Where can I find Interpretation sheets?|
|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.
|I have questions related to the content of a specific IEC publication|
|You will find below categories of technical questions and who to contact:|
Please contact the secretary of the IEC National Committee in your country.
Please contact the secretary of the IEC National Committee in your country, or check here to see if there is an interpretation sheet for the publication you are looking for.
Error in the publication
Please contact us.
If your questions do not fall into any of these categories, please contact us.
|What is Electropedia?|
|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, German, Japanese, Portuguese, Polish, Russian, Spanish and Swedish (coverage varies by subject area).
|How can I find a standard which covers…?|
|Our Webstore is an ideal tool for you to find the standard you want. It offers several search possibilities (by text, by reference, by TC/SC, ICS code and publication date). |
We also offer you a “preview” service to view the cover page, table of contents, foreword, scope and normative references of a standard before purchase. After having obtained search results, please click on the preview icon.
Contact us if you do not find the publication you need.
|What is the validity of IEC 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 given under the publication and entitled "Work in progress".|
|How can I find updates for my IEC standards?|
|If you purchase IEC publication from our Webstore, you will automatically receive an email alert service “Standards Watch” that gives you updated information as and when its amendment(s) or new edition(s) become available.|
If, however, you obtained the standard from other institutions, you may wish to subscribe to our free e-mail service Just Published which is sent out twice a month and lists titles of all newly published standards. To subscribe please click here.
Or, you can send us a list of IEC standards and we will send you a quote / pro forma.

|Can I share IEC publications with my colleagues?|
|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 tables below. Choose between multiple workstations and networking with simultaneous users. There are also national and international ( two or more countries) licences.|
What are your rights? You can preview a copy of the licence here.
Networking with simultaneous users
- 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.

For example IEC 61508-1 has a paper price of CHF 240.-. For up to and including 5 users on a national basis, the price would be 240.- x 2.5 = CHF 600.-(the equivalent of CHF 120.- per user).
Networking - International access
For example IEC 61508-1 has a paper price of CHF 240.-. For up to and including 5 users on an international basis, the price would be 240.- x 3.5 = CHF 840.- (the equivalent of CHF 168.- per user).
To purchase an international networking licence please contact the Customer Service Centre, specifying what publications you are interested in and for how many users they would be for.
Multiple workstations - National access
For example IEC 61508-1 has a paper price of CHF 240.-. For up to and including 5 workstations on a national basis, the price would be 240.- x 1.6 = CHF 384.- (the equivalent of CHF 77.- per workstation).
Multiple workstations - International access
For example IEC 61508-1 has a paper price of CHF 240.-. For up to and including 5 workstations on an international basis, the price would be 240.- x 2.4 = CHF 576.-(the equivalent of CHF 115.- per workstation).

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 you 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. If no orders have been placed in a particular month, no statement will be sent. You can reload your account (again for a minimum of CHF 2'000.-) if your credit is not large enough to buy new publications.
In order to continue benefiting from this service, a minimum of 2 purchases per calendar year is required. If a corporate account remains inactive for an extended period of time, the IEC reserves the right to close the corporate account.
If you wish to open/reload a corporate account please send an email to email@example.com, including the following details:

Please also check the related information.
|How are IEC standards adopted as regional or national standards?|
|The ISO/IEC Guide 21-1 provides the methods for adoption of 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.|
|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.|
|I need information about EN publications / European standards / directives|
|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).
|I need information on Testing / Certification / Test equipment|
|The certification of products according to IEC standards are carried out by conformity assessment bodies:|
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.
If you have questions, you will need to choose the right conformity assessment scheme for your products. Please click here for more information.
