After searching several libraries of data, I found a reference to a heater element. I do not know if this data is the same category that you asked for, namely heater element at 1300 degrees C. The value that I found is 0.02 failures per million hours. The environment was considered to be ground benign which is tightly controlled temperature and humidity levels.
