Title: Specifications for 40×40 cm Ceramic Tiles with 8mm Thickness

Description:
These specifications outline the quality and performance standards for 40×40 cm ceramic tiles with a thickness of 8mm. The criteria cover dimensional accuracy, surface quality, structural and mechanical properties, as well as chemical and thermal characteristics. The adherence to these requirements ensures the tiles’ suitability for various applications.

**Dimensional and Surface Quality (ISO/EN Testing Method A):**
1. *Dimensional Deviation*: The material’s dimensions must maintain a maximum allowable deviation of ±0.5% from the specified measurements. (ISO-10545-2)

2. *Thickness Deviation*: The material’s thickness should exhibit a maximum allowable deviation of ±5.0%. (ISO-10545-2)

3. *Straightness of Edges*: The material’s edges should be straight, with a maximum allowable deviation of ±0.5%. (ISO-10545-2)

4. *Rectangularity*: The material’s shape should be within a maximum allowable deviation of ±0.5%. (ISO-10545-2)

5. *Surface Flatness*: The material’s surface must maintain flatness within a maximum allowable deviation of ±0.5%. (ISO-10545-2)

6. *Color Uniformity*: There should be no noticeable color difference between individual tiles. (Unspecified Method)

**Glossiness:** Glossiness is measured using a glossometer (Specific Testing Method Unmentioned).

**Structural Properties:**
1. *Water Absorption*: The material’s water absorption rate should be below 3%. (ISO-10545-3)

2. *Density (g/cc)*: The material’s density must exceed 2.0 g/cc. (DIN 51082)

**Mechanical Properties:**
1. *Modulus of Rupture*: The material should have a minimum modulus of rupture of 35 N/mm². (ISO-10545-4)

2. *Breaking Strength*: The material should have a minimum breaking strength of 1300 N. (ISO-10545-4)

3. *Impact Resistance*: The material’s resistance to impact must meet the manufacturer’s specifications (Manufacturer’s Guidelines).

**Surface Mechanical Properties:**
1. *Surface Abrasion Resistance*: The material’s surface must resist abrasion as per the manufacturer’s specifications (Manufacturer’s Guidelines).

2. *MOH’s Hardness*: The material’s hardness should be measured using MOH’s hardness scale (Likely EN 101).

3. *Skid Resistance (Friction Coefficient)*: The material’s skid resistance should meet the manufacturer’s specifications (Manufacturer’s Guidelines, Possibly ISO-10545-17).

**Chemical Properties:**
1. *Frost Resistance*: The material should endure freezing conditions without damage. (ISO-10545-12)

2. *Chemical Resistance*: The material should withstand exposure to chemicals without damage. (ISO-10545-13)

3. *Stain Resistance*: The material must resist staining. (ISO-10545-14)

**Thermal Properties:**
1. *Thermal Shock Resistance*: The material should withstand sudden temperature changes. (ISO-10545-9)

2. *Thermal Expansion*: The material’s thermal expansion coefficient should be below 9 x 10^-6 (per degree Celsius). (ISO-10545-8)

3. *Moisture Expansion*: The material should exhibit minimal expansion due to moisture exposure. (ISO-10545-10)

These specifications encompass a comprehensive range of properties, ensuring the material’s suitability and performance across various conditions and applications.
