Does anyone know of a cosmetic specification for part surfaces that indicates acceptable levels of defects (scratches, digs...) for non-optical parts. We have a few parts that we are looking for a uniform exterior surface finish allowing a level of imperfections. I've found a number of company specific guidelines / specifications but have not found anything universal (ASME, MIL, ...)
For our application, the metal surfaces are being sanded or ground to create a uniform finish but occasionally we get in parts with a few scratches. Our QA is rejecting parts that are not perfect so we'd like to give the suppliers some room to get the parts to an acceptable level of quality without requiring perfection. We can create our own standard but if there is already one in existence I'd prefer to reference it.
