We don't know and that is the problem. A lot of manufacturing is about process and we have rigid processes because it reduces risk. There are no checks in this, no qualification/pilot run, no one checking the design who understands the requirements. The only solace I can find is that the factory might have done all of this, they just want to cover their asses in case something goes wrong.
