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.
Tile lippage is becoming more prevalent as the use of large format tiles has gained popularity. The preparation of the substrate is essential for an acceptable installation. Tile lippage can result from: 1) Insufficient preparation of the substrate to accommodate a large format tile. 2) The use of a dry set mortar that was not designed to accommodate the weight of the large format tile. 3) Grout joints that are set too tight with no allowance for warped tile.
