This section of IEC 60598-2 specifies requirements for luminaires intended for use where the necessity of limited temperature on the outer surface exists, due to the risk of combustible dust accumulating on the luminaires, 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 1000 V.
This standard specifically excludes requirements for luminaires for use in explosive gas atmospheres and explosive dust atmospheres.
A special limitation of the temperature of luminaires likely to be covered by combustible dust applies, for instance in locations where textile materials are processed or stored and in spaces where combustible dust, for instance colour powder, wood dust, grain dust, flour and textile dust, are accumulated in large quantities but where the risk of explosion does not exist.
