This section of the scope specifies the requirements for limiting the external surface temperature of lighting fixtures. The use of lighting fixtures does not pose a risk of explosion, but there is a risk of combustible dust accumulation on the fixtures. The voltage of the light source used in the lamp shall not exceed 1000 V. The content of this section does not involve lamps used in explosive gas environments or explosive dust environments. The special temperature limits for lamps that may be covered by combustible dust apply to places such as handling or storing textile materials, as well as places where large amounts of pigment powder, wood chips, grain fragments, flour, and textile debris may accumulate, but there is no risk of explosion in these places. 1.1 Normative References: The clauses in the following documents are referred to in this part of GB 7000 and become the clauses of this part.
