IEC 60598-2-23:2020 specifies requirements for extra-low-voltage lighting systems for ELV light sources, intended for ordinary interior use on supply voltages not exceeding 1 000 V. The luminaires, being connected in parallel, are supplied via freely suspended continuous supporting conductors or profiles, the current in the ELV part of the system not exceeding 25 A.This second edition cancels and replaces the first edition published in 1996 and Amendment 1:2000. This edition constitutes a technical revision.This edition includes the following technical changes with respect to the previous edition (there are no major technical changes, see Annex A):a) The title has been modified to allow the inclusion of other light sources;b) The scope has been updated to be aligned with the other parts of the IEC 60598-2 series and to include other light sources;c) Normative references and the reference to transformer and controlgear standards have been updated;d) The short circuit test (23.7.6.1 and 23.7.6.2) was removed and reference is now made to the same test in Part 1.
