Product Range and Dimensions

The document details a variety of glazed porcelain stoneware tile collections such as Forum Avorio, Forum Beige, Forum Rosso, Cirene, Melissa Avorio, Sauro, Ceo Rosso, and Vesta Rossa. Tile sizes vary from small formats like 10x10 cm (4"x4") to larger sizes such as 30x60 cm (12"x24"), including specialty narrow tiles (e.g., 1.5x10 cm and 3.5x10 cm). Some series are offered in multi-piece sets or mounted on mesh to simplify installation.

Material and Compliance Standards

All tiles are glazed porcelain stoneware compliant with European standard EN 14411 Appendix H BIb GL, indicating water absorption between 0.5% and 3%. This classification applies primarily to plain background tiles. The products also hold UNI-CERTIQUALITY / CEN-KEYMARK certification ensuring conformity with UNI EN 14411 standards, and CCC marking certifying compliance with Chinese import standards. These certifications are supported by company audits and accredited laboratory quality controls.

Technical Data and Packaging

Technical specifications include tile thickness (typically around 8 mm for 10x10 cm tiles), weight per carton, square meters per carton, and number of cartons per pallet. Packaging details vary by product, with some tiles pre-mounted on mesh backing to facilitate installation.

Installation Recommendations

A consistent recommendation across languages is to use a joint width of 2-3 mm during tile laying to ensure optimal installation quality.

Dimensional and Quality Tolerances

Manufacturing tolerances conform to EN ISO 10545-2 standards, including:

• Length and width deviation: ±2% (max ±5 mm) from nominal size.
• Individual tile size deviation from average: ±0.5% to ±0.75% depending on tile surface area.
• Thickness deviation: ±5% to ±10% from average production thickness.
• Straightness of edges: ±0.5% to ±0.75% relative to production dimensions.
• Orthogonality: ±0.6% to ±1.0% deviation.
• Flatness (curvature and twisting): ±0.5% to ±1.0% relative to diagonal or length measurements.

Flatness (Planarity) Specifications

Maximum allowable flatness deviations per EN 14411 Appendix H BIb GL and EN ISO 10545-2 include center diagonal curvature up to ±1.2%, corner length curvature up to ±1%, and diagonal curvature between ±0.6% and ±0.75%.

Appearance and Quality Requirements

At least 95% of tested tiles must be free from visible defects, ensuring high visual uniformity and quality.

Mechanical and Physical Properties

• Bending strength minimum: 30 N/mm² (EN ISO 10545-4).
• Abrasion resistance: Classified from Class I to V as declared by the manufacturer (EN ISO 10545-7).
• Resistance to microfissurization (craquelure): Guaranteed (EN ISO 10545-11).
• Resistance to freezing: Guaranteed (EN ISO 10545-12).

Chemical and Stain Resistance

• Stain resistance classes range from 5 to 1, with a minimum of Class 3 (EN ISO 10545-14).
• Resistance to domestic chemicals: Minimum Class GB, excluding hydrofluoric acid-based detergents (EN ISO 10545-13).
• Resistance to acids and bases: Classes GLA to GLC with minimum Class GLB, excluding hydrofluoric acid and derivatives.

Symbols and Product Classification

The document includes a legend explaining symbols for product identification, covering:

• Designation of wall and floor tiles.
• Chemical and stain resistance indicators.
• Installation recommendations such as joint width and mesh backing.
• Rectified tile identification.
• Shade variation classifications from uniform to random.
• Bending strength and frost resistance markers.
• Anti-slip classification applicable only to unpolished tiles.

Wear resistance is classified on a scale from 1 to 5 based on European and ISO standards, internal testing, and practical experience, guiding appropriate usage and durability expectations.

Additional Notes

Price codes are provided for products sold by square meter or by piece/set. The document references DIN 51130 for slip resistance classification. Multilingual descriptions and recommendations reflect the international market orientation. Some tiles are available mounted on mesh to facilitate installation.
