Ceramic Tile Break Strength

Ceramic tiles used on floors and walls must be able to withstand the expected load bearing capacity of various installations.

Ceramic tile break strength.

Tiles may be glazed or unglazed. As long as the tile does not break under 250 pounds of pressure the tile is considered to be compliant with these standards. L centre to centre length between two support rods in mm. The ansi requires a break strength of at least 250 lbs.

1 1 this test method covers the determination of the breaking strength of ceramic tile ceramic mosaic tile quarry tile porcelain tile and paver tile having a facial area of at least 1 in. Some specialty tiles greatly exceed the minimums. Standard test method for resistance of ceramic tile to chemical substances. Standard test method for measurement of light reflectance value and small color differences between pieces of ceramic tile.

The modulus of rupture is calculated using following formula. The breaking strength is calculated using following formula. F load required to break the tile in n. Water absorption percentage measures the density and hardness of the clay and is the best way to determine the tile s ability to resist thermal expansion its structural strength its ability to resist impacts and the tile s breaking strength.

Standard test method for breaking strength of ceramic tile. Answer the breaking strength minimum industry requirement for ceramic tile is a laboratory test of what is mostly an unsupported tile and isn t directly meaningful in terms of determining what kind of dead and live loads it can endure. Most tiles meet the 250 pound minimum. Using applicable astm tests regular ceramic tile has a breaking strength of 250.

Force on an unsupported portion of tile until breakage occurs expressed in lbs. Where δ modulus of rupture in n mm 2. Aside from being solid porcelain tiles are also hard dense and highly resistant to most heavy impact stresses that it s perfect for commercial use. It is a load limit value applied to three points which the ceramic or porcelain stoneware tile can bear without breaking.

δ 3fl 2bh 2. B width of the tile in mm. Evaluate the break strength rating in comparison with industry requirements. Where s breaking strength in n.

It is associated to the force by which a tile responds when subjected to stress which can break it. For ceramic porcelain stoneware floor tiles bending strength is the perfect indicator of mechanical strength. If you re looking at a break strength lower than that you can t use that tile on the floor. S fl b.
