24、ture 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 e
25、xcludes requirements for luminaires for use in explosive gas atmospheres and explosive dust atmospheres. 24.2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the editi
