The intent of the standard is to define reasonable lippage from one tile to another. When a tile is warped but within standards, all of the corners cannot be set in the plane of the adjoining tiles. Accordingly, the tolerance for variation from tile to tile includes the actual warpage of the tile.
Re: Mill Tolerance. Mill tolerance is the deviation allowed to a pipe manufacturer from the actual nominal thickness of a pipe. 1) This has been considered by relevant pipes ASTM standards, ASME B31 codes, and ASME B36.10 due to incapability of any mill to produce a pipe with an exact nominal thickness defined. The value in all the mentioned standards has been set to 12.5% of nominal thickness. 2) Both positive or negative mill tolerances can exist in a pipe. Positive would not be causing any significant impact but negative may put you in an odd situation if you didn't consider mill tolerance during piping thickness calculation.
