Porcelain and Ceramic tile specifications

Water Absorption

Water absorption is measured using ASTM C373-88. Tiles are weighed, saturated with water

and then weighed again. The percent difference between the two conditions is referred to as the

water adsorption value.

Impervious: Tiles exhibiting 0.5% or less.

Vitreous: Tiles exhibiting more than 0.5% but not more than 3.0%

Semi-Vitreous: Tiles exhibiting more than 3.0% but not more than 7.0%

Non-Vitreous: Tiles exhibiting more than 7.0%

Shade Variations

Tile range from complete consistency to a more appearance. Here’s an overview of color and

shading of individual tile selections

Scratch Hardness (MOHS)

This test it’s based on a scale from 1 to 10. The softest mineral used is talc (1 rating) and the

hardest is a diamond (10 rating). Other minerals of varying hardness providing Mohs scale of

Mineral Hardness values of 5 or more are suitable for most residential floor applications. A value

of 7 or greater is normally recommended for commercial applications.

Breaking Strength

Ceramic and Porcelain tiles used on floors and walls must be able to withstand the expected

load bearing capacity of various installations. A force is applied to an unsupported portion of the

tile breakage occurs. The breaking strength is then recorded in pounds.

CERAMIC ∙ PORCELAIN ∙ MOSAIC ∙ HARDWOOD ∙ LAMINATE FLOOR Chemical Resistance A tile sample is placed in a continuous contact with a variety of chemicals for 24 hours, rinsing the surface and then examining the surface for visible variation. Abrasion Resistance The durability of a glazed tile is measured by observing the visible surface abrasion of the tile when subjected to the testing procedure. This test method includes the following classification system.
