Floor Tile Tolerances

For tiles with all edges less than 15 the maximum allowable variation is 1 4 in 10 and no more than 1 16 in 12.

Floor tile tolerances.

Qld standards and tolerances for ceramic and porcelain tiles. When a tile is warped but within standards all of the corners cannot be set in the plane of the adjoining tiles. Ansi a137 1 specifications for ceramic tile has established allowable tolerances criteria for each type or category of ceramic tile. 7 vba guide to standards and tolerances 2015 11 floor and wall tiling 54 11 01 floor and wall tiling 54 11 02 floor and wall tiling where the builder supplies the tiles 54 11 03 floor and wall tiling where the owner supplies the tiles for laying by the builder 54 11 04 floor and wall tiles where the owner supplies and lays the tiles 54.

There are rectified porcelain tiles that are more consistent in size tolerances where they recommend 1 16 inch wide grout joints. The intent of the standard is to define reasonable lippage from one tile to another. For large format tiles with one. Accordingly the tolerance for variation from tile to tile includes the actual warpage of the tile.

Up to 10 of tiles as supplied. Tolerances when tiles 8 x 8 or larger had been selected. Sampling and basis for acceptance allows one tile in 10 to be outside the above dimensional tolerances i e. If your tile has a rectified machine trimmed edge then there is a higher requirement for size control as the joint gaps will be narrow.

The ansi a108 02 standards say that acceptable lippage for floor tiles with a grout joint width of 1 16 to less than 1 4 is 1 32 plus the allowable inherent warpage of the tile. Ceramic tiles have always had warpage and other dimensional variations although current production technology results in more consistency. This information is critical for any new tilers. Table 1 in as 4459 1 1999 also iso 10545 1 1995 ceramic tiles part 1.

Floor and wall tiling tolerances and standards in accordance with queensland regulations below is some helpful yet brief information about the different standards and tolerances that exist for floor and wall tiling within queensland. Tile lippage which is were one edge of a tile is higher or lower than the adjacent tile edge is normal to a degree but there are limitations. If the grout joint width is 1 4 or greater then the allowable warpage is 1 16 plus the allowable inherent warpage of the tile. 2 how many tiles from any one batch can be outside the tolerances described in iso 13006 1998.
