installations. The tile industry uses ASTM C648-04 to determine the strength and durability of the tile. A force is
applied to an unsupported portion of the tile specimen until breakage occurs. The ultimate breaking strength is
then recorded in pounds. Final selection of the tile should be based upon the breaking strength and the appropriate
installation method. Tile integrity is critically dependent upon proper installation. Marazzi recommends strict
adherence to industry installation guidelines set forth in ANSI A108, A118 and A136.
Chemical Resistance, ASTM C650-04
Chemical resistance is measured using ASTM C650-04. A tile sample is placed in continuous contact with a variety
of chemicals for 24 hours, rinsing the surface and then examining the surface for visible variation.
Shade Variations
Tiles range from complete consistency to a more random appearance.
Here’s an overview of color and shading of individual tile selections:
Shade variation V0 Monochromatic appearance
Pieces of the same shade value are very uniform and
smooth in texture.
Shade variation V1 Low variation
Dierences among pieces from the same production run
are minimal.
Shade variation V2 Medium variation
Clearly distinguishable dierences in texture and/or
pattern within similar colors.
Shade variation V3 High variation
While the colors and/or texture present on a single piece
of tile will be indicative of the color and/or texture to be
expected on the other tiles, the amount of color and/
or texture on each piece may vary significantly. It is
recommended that the entire range be viewed before
selection.
Shade variation V4 Random variation
Random color and/or texture dierences from tile to
tile, so that one tile may have totally dierent colors
and/or textures from that on other tiles. Thus, the final
installation will be unique. It is recommended that the
entire range be viewed before selection.
Frost Resistance
Industry criteria dictate that tile shall not exceed 5% water absorption to be recognized as frost resistant. To be
recognized as Porcelain tile, the water absorption rate cannot exceed 0.50% (impervious). Wall tile must not exceed
20% water absorption and is not frost resistant.
