In areas which are explosion-hazardous due to com-
bustible dusts, the surface temperature must not exceed
two-thirds of the ignition temperature in ° C of the
dust/air mixture. The temperatures of surfaces on which
hazardous deposits of combustible dusts can be formed,
must not exceed the glow temperature of the relevant
dust minus 75K. Greater safety margins are required if
the thickness of the dust layer exceeds 5 mm.

The corresponding surface temperatures can be derived
from the lowest values for glow and ignition
