Tile not Manufactured to Industry Standards

MANUFACTURERS' STANDARDS

American National Standard Specification for Ceramic Tile A137.1, A137.2, and A137.3 are the only nationally recognized specification for ceramic tile.

Many domestic and foreign manufacturers of tile produce tile products made to the "manufactur er's own standards." In many cases, these standards allow variation in shade, density, consistency of texture, wear resistance, absorption, fractures, squareness, size, thickness, warpage, and mounting that are considerably less stringent than ANSI standards. Some manufacturers make broad disclaimers in their literature, virtually relieving themselves of responsibility for owner dissatisfaction or for the performance and appearance of their products. Some disclaimers deny responsibility after the tile is installed. Often, visual inspection prior to installation does not reveal inadequacies of the tile's performance or possible installation problems.
