I'm not an ISO expert either, but my understanding of ISO is that it requires a company to follow its written policies. I don't think ISO requires a company to change PNs if FFF change.I'm not an expert on ISO9000, but would imagine it specifies you need a proper Configuration Management policy? I'm an ME in the Aerospace/Defense business; not changing the part number, once a baseline was established and product was in the field, after a major design change would be unheard of.
My premise is there was no design change, only an improved inspection regime. I thought for a while that the reason it took so long for the recall to be implemented was that Ford was trying to figure out if they could develop an inspection process that dealers could use to examine whether the existing hoses were OK; only replacing those that were deemed defective, instead of all of them. Just speculation on my part.
A revised spec or inspection procedure that alters which parts are accepted is still a FFF change.
