IEC 60598-2-24:2013 series specifies requirements for luminaires intended for use where the necessity of limited temperature on the outer surface exists, due to the risk of thermal effects, combustion or degradation of materials but where the risk of explosion in the atmosphere does not exist. The luminaires are for use with electric light sources on supply voltages not exceeding 1 000 V. This standard specifically excludes requirements for luminaires for use in explosive gas atmospheres and explosive dust atmospheres. This second edition cancels and replaces the first edition published in 1997. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) change of required degree of protection from IP6X to IP4X to harmonize with the international wiring rules;
b) temperature limits introduced for glass surface of any light source exposed to risk of dust.

This publication is to be read in conjunction with IEC 60598-1:2008.
