dear,
there will instruments to be installed for fuel system in KSA where the maximum outdoor ambient temperature reaches 85C without sunshade.
The instruments are specified as class T3 where the maximum surface temperature can be up to 200 degree C.
Supplier is giving instruments satisfiying 85C as class T6.... my question, is this acceptable? i mean the supplied instruments are specified as working for the maximum outdoor temperature which is 85 degree C.
shall i accept them or stick to the requirement of class T3 (max=200 degree C).
I want to understand is the specified maximum temperture from Atex as T3, does it mean that the instruments will be still functional even an explosion has occured making the temperature reach 200 degree C?
thanks for your clarifications.
