IEC 61243-1 Ed. 2.1 b:2009
Live working - Voltage detectors - Part 1: Capacitive type to be used for voltages exceeding 1 kV a.c.
"IEC 61243-1:2003+A1:2009 is applicable to portable voltage detectors, with or without built-in power sources, to be used on electrical systems for voltages of 1 kV to 765 kV a.c., and frequencies of 50 Hz and/or 60 Hz. This part applies only to voltage detectors of capacitive type used in contact with the part to be tested, as a complete device including its insulating element or as a separate device, adaptable to an insulating stick which, as a separate tool, is not covered by this standard (see 4.4.1 for general design). The contents of the corrigendum of October 2005 have been included in this copy."
