RODUCT INFORMATION
Temperature limits for explosion-hazardous
dusts In areas that are potentially explosive
due to combustible dusts, the surface temperature
must not exceed two-thirds of the ignition temper-
ature in C of the dust/air mixture. The tempera-
tures of surfaces on which hazardous deposits of
combustible dusts can be formed must not exceed
the glow temperature of the relevant dust that is
reduced by 75K. Greater safety margins are re-
quired 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 temperatures of dusts specified in the
HVBG/BIA report 12/97 "Combustion and explo-
sion characteristics of dusts".
Examples:
Synthetic rubber, soot-containing:
Glow temperature 220 C - 75 C = 145 C max.
permissible surface temperature
Stearic acid:
Ignition temperature 190 C x 2/3 =126 C max.
permissible surface temperature
