(Amendment)Low-voltage switchgear and controlgear - Part 1: General rules
Low-voltage switchgear and controlgear - Part 1: General rules
The purpose of this standard is to harmonize as far as practicable all rules and requirements of a general nature applicable to low-voltage switchgear and controlgear in order to obtain uniformity of requirements and tests throughout the corresponding range of equipment and to avoid the need for testing to different standards. All those parts of the various equipment standards which can be considered as general have therefore been gathered in this standard together with specific subjects of wide interest and application, e.g. temperature-rise, dielectric properties, etc.

Nizkonapetostne stikalne naprave - 1. del: Splošna pravila (IEC 60947-1:2007/A1:2010)
Namen tega standarda je, kolikor je to praktično, uskladiti vsa pravila in zahteve splošne narave, ki veljajo za nizkonapetostne stikalne naprave, da se doseže enotnost zahtev in preskusov za celoten ustrezen razpon opreme in da se izogne potrebi po preskušanju za različne standarde. Vsi ti deli različnih standardov za opremo, ki se lahko štejejo za splošne, so bili potemtakem zbrani v tem standardu, skupaj s posebnimi temami, za katere velja široko zanimanje in uporaba, npr. dvig temperature, dielektrične lastnosti itd.
