Non-incendive and transmitters

[Bankster]

If my transmitter is FM ClassI, DivI would there be a need/requirement for a seal on a transmitter if the circuit is non-incendive?

If for some reason it is not working normally. It could still ark. The standard you mention is not intended to cover equipment for use in Class I and Class II, Division 1 locations, such as equipment constructed to be intrinsically safe, dust ignition-proof, or explosion-proof. Such equipment is, however, suitable for use in Class I and Class II, Division 2 locations in the same group and temperature class for which it is suitable.
