IEC 60915:2006 contains preferred dimensions for shaft ends and bushes and for the mounting of single-hole, bush-mounted, shaft-operated variable capacitors, variable resistors and potentiometers. If other dimensions not listed in this standard have to be used, it is recommended to select them also from IEC 60390 and IEC 60620. This second edition cancels and replaces the first edition published in 1987 and constitutes a minor revision, related to tables, figures and references. This bilingual version, published in 2008-07, corresponds to the English version. The contents of the corrigendum of December 2008 have been included in this copy.
