OVERVIEW

This list shows the main international, European and British standards which may be relevant to the design or application of variable-speed drives.

International Electrotechnical Commission (IEC) standards are generally preferred for the purposes of harmonisation to facilitate world trade. They are not in themselves mandatory, whereas national standards and European harmonised standards may be adopted under legally binding regulations and become effectively or actually mandatory.

Many IEC standards are identical in technical content with the CENELEC (EN...) standard of the same number; in this case, the CENELEC standard is listed here. There may be discrepancies when revisions are ratified at different times, and in that case both are listed.

IEC standards with four or less digits in the number have been renumbered by the addition of 6000. Where the standard has not been revised recently, the old number may still appear on the document.
