What is the Bending Strength or MOR of a Porcelain Tile?
Porcelain Tiles are known for many superiority to its ceramic counterpart, one of them being hard to break the tile and having a high load capacity. In this article we will briefly try to cover topics like what is the bending strength and / or MOR of the porcelain tile as well how the tiles are tested to check the breaking strength practically at the laboratory or manufacturing facilities.
We need to define few parameter to learn about these :
Now that we got our theory clear, now it’s time to learn how the actual tile is tested for the MOR at a laboratory and factory.
Each of our porcelain tile manufacturing units has a laboratory to check the raw material for various parameters, one of them being the MOR test. We have an equipment to test the Bending strength in the laboratory to check a small sample of the tile. The tile should pass the test in order to proceed with the raw material to produce the actual tile.
During the production of the porcelain tile, we check the MOR with the larger version of the lab equipment. Here the actual tile in the production is checked for the MOR value on an interval of every hour and for each and every batch of the production, those records are maintain in quality control reports.
The tile is between the test rollers in the machine and then the load is applied by the machine until the tile is broken. This machine gives us the bending strength value. Some of the machines might be calculating with other formulas or units, so then we need to convert it to give the value in N/mm2.
That is how the porcelain tiles are tested for the MOR or the bending strength of the tile. Generally as per the international standards for tile : EN 14411 - ISO 10545-4, the bending strength of the porcelain tile should be more than 35 N/mm2 for the pressed tiles.
At TIEIC, all of our pressed tiles are in the range of 40 N/mm2 or more. You can check TIEIC’s collection of porcelain tile at our website.
