The big question while installing the tile & Stone will be how much shall be the tile joint width?
Let see which standard has provided the answer for this:
A108.19 Interior Installation of Gauged Porcelain Tiles and Gauged Porcelain Tile Panels/Slabs by the Thin-Bed Method bonded with Modified Dry-Set Cement Mortar or Improved Modified Dry-Set Cement Mortar - 2017
17 Workmanship, lippage, and grout joint size:
17.2 To accommodate the range in facial dimensions of the tile supplied for a specific project, the actual grout joint size shall be at least three times the actual variation of facial dimensions of the tile supplied. Example: for tile having a total variation of 1/16 in. (1.6 mm) in facial dimensions, a minimum of 3/16 in. grout joint shall be used. In no circumstance shall the grout joint be less than 1/16 in. (1.6 mm). Projects requiring field fabrication may also of necessity require additional variation from the grout joint size specified.
Hence check the Tile & Stone manufacturer's TDS and find out the dimension tolerance. Multiply with 3 and you get the answer in inches, convert it to mm.
If you know any other standard which talks about the tile join width dimension, please comment below.
