Technical data
Our reading on the left, the standard on the right.
Values are typical for current production runs, tested to the European methods named in the last column. Where a harmonised standard sets a limit we quote it next to the value. The report for your material goes out with the order.
| Parameter | Unit | Petrarra | Limit / standard |
|---|---|---|---|
| Apparent density | g/cm³ | 2.45 | EN 1936 — declared value, no minimum |
| Open porosity | % | 2.9 | EN 1936 — declared value |
| Water absorption, atmospheric | % | 1.6 | EN 13755 — declared; Denizli basin runs 0.9 – 2.6 |
| Compressive strength | MPa | 62 | EN 1926 — declared; basin range 44 – 70 |
| Flexural strength, concentrated load | MPa | 11.4 | EN 12372 — declared value |
| Abrasion resistance, wide wheel | mm | 21 | EN 14157 — lower is better; declared |
| Frost resistance | cycles | 48 | EN 12371 — flexural loss under 20 % required |
| Slip resistance, unpolished, dry | USRV | 41 honed / 57 tumbled | EN 14231 — declared per finish |
| Thickness tolerance, calibrated tile | mm | ± 1.0 | EN 12057 class 1 permits ± 1.5 |
| Length and width tolerance | mm | ± 0.8 | EN 12057 class 1 permits ± 1.0 |
| Flatness deviation, 40.6 cm tile | mm | 0.4 | in-house reject above 0.6 |
| Reaction to fire | class | A1 | EN 13501-1 — natural stone, without testing |
| Filling material | — | Resin + cement, colour matched | unfilled supplied for external use |
Denizli stone is not one material. The values above are typical for the Ivory and Classic travertine range; Country Classic and Walnut are denser and read differently on porosity and absorption, and the marble and onyx programme is a separate sheet. Ask for the material-specific report.
