Technical Tests and Standards
 
ISO 10545-7

ASTM C1027
Resistance to Abrasion and Tread Wear
Abrasion resistance is the capacity of the glazed surface to resist the wear caused by foot traffic or the abrasion caused by mechanical equipment. The wear action determines the suitable applications for each tile.

Class 2 Residential: suitable for residential excluding kitchen, entryways, and stairs
ISO 10545-3

ASTM C373
Water Absorption
Absorption is the product capacity for water penetration. Porcelain tile is an impervious, very dense product with a very low absorbency rate. Ceramic tiles are more porous and generally less durable than porcelain tiles due to a less dense body composition. Ceramic wall tiles are the least dense and can have a water absorption rate of over 10% of its weight.
Porcelain tile is less than .5% absorption by definition therefore it meets ISO standard 10545-3.
ISO 10545-13

ASTM C650
Chemical Resistance
The ISO standard 10545-13 tests a tiles resistance to chemical interaction. Tiles, which are going to be exposed to aggressive chemical, should be evaluated based on the performance of the test. (Commercial kitchens, swimming pools).
ISO 10545-4

ASTM C648

Break Strength
Tests the tiles resistance to heavy loads. The breaking strength is the force needed to break the tile.
ISO 10545-14

ASTM C1378
Stain Resistance and Maintainability
Method applicable to all working surface of ceramic tiles to determine their resistance to stains. Each staining agent must remain on at least 5 testing samples, for at least 24 hours. Removal of the staining agent takes place in subsequent steps using various agents and cleaning procedures.

Class 5 Stain removed with hot water
Class 4 Stain removed with weak cleaner
Class 3 Stain removed with strong cleaner
Class 2 Stain removed with specific solvents
Class 1 Stain not removed

To meet the standard a tile must be rated Class 3 or higher.
