I have a circuit that can generate a 0.13mJ spark, well below the minimum ignition energy (MIE) of methane (0.28mJ).

I want to see if this circuit is intrinsically safe for a Class 1 Div 1 Group D environment with a minimum ignition current ratio (MIC) spec of 0.8.

What to I need to convert between MIE and MIC?

Thanks,

John D
