ATEX intrinsic safety certification of product nRF9160

[Lukas Gabriel]

Would you like to know how to access the produte nRF9160 intrinsic safety certification? I needed this certification, to find out if the product meets intrinsic safety requirements for me to use it in my project. 

I await your response, thank you very much.

Dear Lukas,

nRF9160 is not certified formally for ATEX. However, we have tested (with external certifiation body) nRF9160 as component for ATEX compliance according to IEC/EN 60079-0 and IEC/EN 60079-11. Test certification criteria for nRF9160: II 1G Ex ia IIB Ga. As a result we have intrinsic protection values: Ci, Li, Ui, Ii and Power, including temperature operation limits. Temperature is defined for classification T4: "maximum service temperature range of -40°C ≤ Tservice ≤ 85°C at the installation location".

Sincerely,  Mika

Dear Lukas,

You wrote: "As a result we have intrinsic protection values: Ci, Li, Ui, Ii and Power, including temperature operation limits. "

What are those limits?

What do you mean with "protection values?

In a differents post Heidi stated that the intrinsic Capacitance Ci is 73 uF, hence already too high for ATEX certifiaction!?
