Anotace

IEC 60670-22:2024 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60670-22:2024 applies to boxes, enclosures and parts of enclosures (hereafter called "boxes" and "enclosures") for electrical accessories with a rated voltage not exceeding 1 000 V AC and 1 500 V DC intended for household or similar fixed electrical installations, either indoors or outdoors. Boxes and enclosures complying with this document are suitable for use at ambient temperatures not normally exceeding +40 °C, but their average over a period of 24 h does not exceed +35 °C, with a lower limit of the ambient air temperature of -5 °C. Other temperatures outside the above range can apply according to the classification of the boxes and the enclosures. This document applies to junction connecting boxes or tapping connecting boxes or both. This second edition cancels and replaces the first edition published in 2003 and Amendment 1:2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) addition of cable joints as a new type of box with the related tests and requirements; b) addition of tests and requirements for boxes and enclosures exposed to direct sunlight with the related Annex CC; c) addition of connecting boxes and enclosures having encapsulation capability as a new type of boxes with the related tests, requirements and related Annex DD.
