IEC 60598-2-24:20 13系列规定了灯具的要求，这些灯具用于由于热效应、材料燃烧或降解的风险而需要限制外表面温度，但不存在大气中爆炸的风险。灯具与电源电压不超过1 000 V的电光源一起使用。本标准特别排除了在爆炸性气体环境和爆炸性粉尘环境中使用的灯具的要求。这第二版取消并取代了1997年出版的第一版。它构成技术修订。与上一版相比，此版本包括以下重大技术变更: a)将所需防护等级从IP6X改为IP4X，以符合国际布线规则；b)对暴露于灰尘风险的任何光源的玻璃表面引入的温度限制。 本出版物应与IEC 60598-1:20 08一起阅读。

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.
