Required software for downloads?
In order to use some of the features or services provided by the IEC, you may need additional software. The links below are provided to help you find such software. Please note that the IEC cannot be responsible for either these links or the software products themselves. Also, in most cases, there are alternative solutions which work perfectly well.

• To read Acrobat PDF files, you will need Adobe Acrobat Reader.
• To open compressed files (zipped files), we suggest using Winzip.

Wrong web site?
Our initials are CEI in French, and IEC in English. Here are some other organizations which use these acronyms. If one of these is what you are really looking for, here is the link to their site:
