Gases and dusts are classified according to their ignition properties For gases and vapors, the gas group (explosion group) is determined according to:
MESG - maximum experimental safe gap (IEC 60 079-1A)
MIC - minimum ignition current ratio relative to methane (IEC 60 079-3)
The danger of the gases increases from gas group IIA to IIC.
Temperature class is based on the auto-ignition temperature of the material
