Note:
Burrs, nicks, and scratches are defined as material raised above normal surface, which if not removed would
prevent complete and proper mating of parts and sealing surfaces. Where nicks or scratches allow bare
metal to show through a protective finish, note defect and assign part for repair. Dents or damage must not
impair finish or functional operation of any part.
