Note: Unaided eye includes vision assisted by corrective lenses normally worn by the person inspecting the specimen.
5.1.2 Performance Visible surfaces shall be free of blemishes, cracks, die marks, pinholes, and wrinkles. Surface details that are part of the design shall not be cause for rejection.
5.2 Warpage test
5.2.1 Procedure The specimen shall be placed on a flat and level surface to ascertain the amount of deviation from the horizontal plane that exists at its edges. A feeler gauge of a thickness equal to the total warpage allowed in Clause
5.2.2 shall not slide under the specimen unless forced. If the specimen rocks on two opposite corners, the horizontal plane shall be determined by placing one feeler gauge, as thick as the total warpage allowed, under a corner that does not touch the flat and level surface. This gauge is inserted by not more than 1/16 in.Forcing the specimen down on this gauge, a second feeler gauge of the same thickness shall not slide under the specimen at any other point.ASME A112.3 pdf download.ASME A112.3-2017 pdf free download
