If the measured variation appears to be excessive then; B) Notify and then discuss with your supplier. Excessive ceramic tile size variation and squareness problems occur differently in a stamped (moulded) tile than a rectified edge tile. This allows the tile to be installed with a narrower grout joint width. }. Stand all of the tiles on edge and see if any of them vary in length. It is their "deluxe" series.  −  Rectified tiles are those that have been trimmed to size with dressed (or finely finished) edges using special cutting tools. .hide-if-no-js { Cause: The tile size specified for fixed size tessellation is smaller than the tolerance as specified in the layer metadata. 6 any piece that can fit into an area of 49 cm 2 ).

This means that the tiles can be 297.75mm to 302.25mm and still be within the standard. If any issues were detected read on; These out of square tiles fail the squareness test using the 90 degree angle ruler, Steps: As in sizing, try to determine the pattern of occurence. }, Help us to keep this site secure 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. six If the measured tile size variance is within the tolerance specified by the manufacturer you will have to use the joint gap size recommended by the manufacturer. 0000005696 00000 n }. There are a number of British Standards applicable to the wall and floor tile industry; these include Standards which define ceramic and natural stone tiles, tile fixing, tile adhesives and grouts. Accordingly, the tolerance for variation from tile to tile includes the actual warpage of the tile. 0000004177 00000 n Help us to keep this site secure The maximum of 2 mm applies to large tiles, hence a 600 mm tile would have a maximum variance of +/- 0.33%.  =  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. .hide-if-no-js { Non-Rectified Tile : Size Tolerance +/- 1.5mm.
