Over deze norm
|Commissie||Werkvoorschriften - NEC 623|
NEN-EN-IEC 61243-3 is applicable to hand-held two-pole voltage detectors with their accessories (crocodile clips and detachable leads) to be used in contact with parts of electrical systems: - for a.c. voltages not exceeding 1000 V at nominal frequencies between 16 2/3 Hz and up to 500 Hz, and/or - for d.c. voltages not exceeding 1500 V. Contact electrode extensions are not covered by this standard. Voltage detectors covered by this standard are intended to be used under dry and humid conditions, both indoor and outdoor. They are not intended to be used under rain conditions. Voltage detectors covered by this standard are not intended to be used for continuous operation. Voltage detectors covered by this standard are intended to be used up to 2 000 m above sea level. This standard also includes provisions for the following supplementary functions when available (see Annex B): - phase indication, - rotating field indication, and - continuity check. Other supplementary functions are not covered by this standard. Voltage detectors covered by this standard are not considered as measuring devices. Relevant safety requirements for measuring devices are included in IEC 61010 series.
