If final inspection is the service being provided, that would be a reasonable scope, wouldn't it? I have used a company that manufactured products and had a very capable lab with a lot of downtime, and the lab was certified as a service independent of the product manufacturing. Their lab services were ISO17025, IATF16949, ect, but the consumer goods they manufactured obviously did not need that certification. But I think this discussion might be a little off topic.
This is not what we do, but imagining it this way might give a better picture of the issue. The OP1 is the mining of iron ore and processing it into metal stock. the OP2 is machining and treating the metal into the metal fasteners the customer wants. Before accepting the metal stock into inventory for OP2, we do testing and inspection like one would for a normal external supplier. We do not want anyone seeing our super special mining techniques in OP1.
