Many technical universities subscribe to IEC Webstore or IHS Markit standards packages. If you are a student, professor, or affiliated researcher, you can download the PDF for free from your campus network. Public libraries in large cities sometimes have subscriptions to engineering standards databases.
While I can guide you on where you might find a free PDF, I must note that accessing standards for free can sometimes be challenging due to copyright laws and the need for standards organizations to fund their activities. Here are a few strategies:
IEC standards are protected by international copyright laws (Berne Convention). Unauthorized distribution is illegal. Companies have been fined for using unlicensed copies in their quality systems.
If you are in a developing country, you may qualify for free access via the IEC National Committee under the “IEC Just Published” program or through IEC Academy webinars. Check with your country’s electrotechnical committee (e.g., ANSI in the US, BSI in the UK, DKE in Germany).
If you have landed on this page searching for an “IEC 60034-9 PDF free download” , you are likely an electrical engineer, maintenance technician, or procurement specialist dealing with industrial motors. You need the official standard for determining the noise limits of rotating electrical machines—but you may not want to pay the high cost of an official IEC document.
