Characteristic

Tile from IRIS Industrial has various kind of glaze and characteristics. Finding your proper characteristic and design.

DISTORTED & INCONSISTENT TILE SIZES

As a result of the hand-made production process, IRIS tiles are shrunk and expanded form burning at high temperature. This may cause inconsistent size and shape of tiles.

TOLERANCE OF TILE DIMENSION IN ALL MODEL
± 5 mm. | All Model

INCONSISTENT COLOUR

Due to the burning technique at the temperature over 1,200° celsius, the colour and coated surface, including the number of glazes (for crystal glazed tiles), are different from tile to tile.

SILVER | MR005 Some glaze has variable shade of colour. Light, medium and dark shade may occur. Silver glaze is the best example to explain.

JASMINE BLUE | MR011 Some glaze has variable in number of crystal on surface such as Jasmine and Iris glaze.

THE MOON | MR009 Some Metallic glaze, There are variable in number of Crystal on surface.

PYTHON | MR008 Python is strange, There is variable in pattern blending of dark gold and matt black colour.

WATER ABSORPTION | ISO 10545-3


Absorption is the product capacity for penetration.

IRIS tile is very dense product with a very low absorbency rate.

1.18 % | All Model

BREAK STRENGTH | ISO 10545-4


Test the tile resistance to heavy loads. The breaking strength is force needed to break the tile.

All Model  |   607.22 kgf/cm²

ROCCA  |  294.78 kgf/cm²

SERPENT  |  190.18 kgf/cm²

ABRASION RESISTANCE | ISO 10545-7


Test the tile resistance of materials and structures to abrasion can be measured by the amount of mass lost per 1,000 cycles of abrasion

All Glaze
Less than 0.07%

FROST RESISTANCE | ISO 10545-12


After 100 Freeze-thaw cycles the tile tested showed no evidence of damage.

CHEMICAL RESISTANCE | ISO 10545-13


The ISO standard 10545-13 tests a tile resistance to chemical interaction. Tiles, which are going to be exposed to aggressive chemical, should be evaluated based on the performance of the test.

SLIP RESISTANCE | DIN 51130


These are German test methods that require an operator with standard footwear (DIN51130) or barefoot (DIN51097) to walk on the test surface. Known also as the ramp test, the inclination angle of the test surface, can be varied under the control of the operator, the test surface can be sprayed with liquid contaminant at a prescribed rate, motor oil (DIN51130) to a soap solution (DIN51097). The operator, wearing a fall restraint harness gradually increases the inclination of the ramp until he or she feels insecure or slips when walking up and down the slope. The angle at which slipping occurs is used to establish a classification “R” value for the shod test.

SLIP RESISTANCE | ASTM C1028


This standard tests the anti-slip properties by determining the coefficient of friction between the tile and a body with a rubber surface. This test is performed in both dry and wet conditions. The COF (coefficient of friction) is defined as the horizontal force needed to overcome the vertical force of the objects weight.
