How the detection ranking of the testing machine shouls be done?
e.g. in a process for 'X' product, the product is tested for leak in leak testing machine. Now as per the fourth edition of FMEA manual (page99)
: Assume the failure has occured & then access the capabilities of all "current process controls" to prevent shipment of the part having this failure mode.
Now in this leak test should we assume that leak testing machine has failed to detect the leak & we have to detect in next process before shipment?
Is this logic clear? or we should not consider failures at testing machine?
Please help!
