Ceramic Tile Tolerances

This document con tains both a definition and specific dimensional tolerances for rectified tile.

Ceramic tile tolerances.

Ceramic tiles are generally manufactured to conform to the european agreed standard of which the english language version is bs 6431 or the newer iso dis 10545. 2 the tiles themselves may not be as flat as one would ordinarily think. The intent of the standard is to define reasonable lippage from one tile to another. 2b place another tile face down directly over the first.

For example if you have a 400 mm square tile then the maximum gap between the straight. Sampling and basis for acceptance allows one tile in 10 to be outside the above dimensional tolerances i e. 2a take one tile and place it face up in a table or counter. Up to 10 of tiles as supplied.

Tolerances when tiles 8 x 8 or larger had been selected. Accordingly the tolerance for variation from tile to tile includes the actual warpage of the tile. 2 how many tiles from any one batch can be outside the tolerances described in iso 13006 1998. Maximum deviation from square edge is 0 5 of length of tile.

However as of 2011 subsurface tolerances for tile installation based on tile unit size have been updated in the tcna handbook. Manufacturing tolerances for ceramic tiles. When a tile is warped but within standards all of the corners cannot be set in the plane of the adjoining tiles. 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.

As an example under iso13006 the tolerances are. Both specifications use the water absorption characteristic to define product type as water absorption is a commonly related item for all. Bowing or curvature is one of the most common imperfections however bowed tiles are deemed acceptable if they are within specified tolerances. For large format tiles with one.

There are ways to measure. Standard specification for ceramic tile that is currently being balloted rectified tiles are addressed. The size requirements for rectified tile tile q a by bill griese rectifying the misconceptions associated with rectified tile and. Many times larger tiles are warped curved pillowed or just plain crooked.

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. Table 1 in as 4459 1 1999 also iso 10545 1 1995 ceramic tiles part 1. 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.
