Temperature table for use in Zone 21
For devices for use in Zone 21, the ambient temperature-fluid temperature dependency,
indicated in the temperature table for Zone 1 and Zone 0, applies with the following
restrictions in the ambient temperature, however:
–20 °C ≤ T ≤ 55 °C
a
Surface temperature for devices for use in Zone 21
The surface temperature of the device may not exceed 2/3 of the ignition temperature
of a dust cloud. The maximum surface temperature must observe a safety distance of
75 K from the glow temperature of a dust layer of 5 mm.
Example: configuration of the temperature class T4 (135 °C) is suitable for dust with
an ignition temperature of 202.5 °C (1.5 x 135 °C) and a glow temperature of 210 °C
(135 °C + 75 °C).
