Floor Tile Tolerances

Up to 10 of tiles as supplied.

Floor tile tolerances.

Ceramic tiles have always had warpage and other dimensional variations although current production technology results in more consistency. 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. 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.

This information is critical for any new tilers. 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. 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. There are tolerances for tile lippage.

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. Tolerances when tiles 8 x 8 or larger had been selected. Table 1 in as 4459 1 1999 also iso 10545 1 1995 ceramic tiles part 1. When a tile is warped but within standards all of the corners cannot be set in the plane of the adjoining tiles.

2 how many tiles from any one batch can be outside the tolerances described in iso 13006 1998. For large format tiles with one. 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. Sampling and basis for acceptance allows one tile in 10 to be outside the above dimensional tolerances i e.

Qld standards and tolerances for ceramic and porcelain tiles. Tolerances for modern rectified edge tiles are expected to be extremely tight. Accordingly the tolerance for variation from tile to tile includes the actual warpage of the tile. Ansi a137 1 specifications for ceramic tile has established allowable tolerances criteria for each type or category of ceramic tile.
