While doing a PFMEA for a six sigma project "To improve silver purity of a Pyro refining operation " I do need some help in deciding "detection ranking" of a failure mode .
The Potential Cause(s)/ Mechanism(s) of Failure : Due to small capacity of Bottom blowing oxygen cupel of smaller size it is difficult to control temperature because of small thermal capacity.
Since We know that our furnace is having a limitation with regard to size .
Result :- Occurrence rating =10
What about Detection rating ????
We are almost certain about this fact.
At present no design control exist.
A case study would also help in this regard.
