Vitrified are very popuar substitutes for Marbles, Granites and other materials. They are popular due to their strenght, low water porosity and a cost effectiveness.
So what constitutes the specifications for calling a Tile a Vitrified Tile.. ISO (under ISO 13006) provides guidelines that define the characterestic of Vitrified Tiles
1. For Polished Vitrified Tiles.
- Tiles shall be hard, dense, impervious and frost resistant.
- Water absorption of tiles shall be less than 0.5% and flexural strength (Modulus of Rupture) shall be more than 35
- Vitrified polished porcelain floor tiles shall be provided of sizes, colour, shades, texture and designs as indicated and if size not indicated it shall be 600mm x 600 mm/ 605 x 605 mm.
- The thickness shall be as specified by the manufacturer but not less than 8mm.
2. For Unpolished Vitrified Tiles.
Heavy duty vitrified tiles shall be acid and alkali resistant, weather proof, anti skid and abrasion resistant as per International
- Water absorption<2%
- Flexural Strength>35 N/Sqmm
- Moh's Hardness>6
- Abrasion resistance<204mm.
- Heavy duty vitrified tiles shall be of sizes, colour, texture and designs as indicated but size if not indicated it shall be of 300mm x 300 mm. The thickness shall be as specified by the manufacturer
