IIC
Explosion group; for gases needing the lowest amount of energy to ignite
an explosion, e.g. hydrogen
T4
Temperature class, defining that the maximum surface temperature a gas
can reach in this apparatus (SISO3) stays always below 135 °C
Gc
Equipment for explosive gas atmospheres, having a normal level of
protection, which is not a source of ignition in normal operation.
