Tested, not assumed
Independently tested to the relevant BS EN standards
Our Shahabad limestone range is independently laboratory tested against the BS EN standards a UK specifier expects to see, with batch testing carried out on production runs and a Declaration of Performance and UKCA marking issued with every shipment.
Test results
Reference results by standard
| Property | Standard | Typical result |
|---|---|---|
| Compressive strength | BS EN 1926 | ≥ 65 MPa |
| Flexural strength (concentrated load) | BS EN 12372 | ≥ 9 MPa |
| Water absorption at atmospheric pressure | BS EN 13755 | 3.5–4.5% by mass |
| Density and open porosity | BS EN 1936 | 2,450–2,550 kg/m³ |
| Abrasion resistance (wide disc) | BS EN 14157 | ≤ 21 mm groove length |
| Slip resistance, wet (pendulum) | EN 16165 Annex C | PTV 45–55 depending on finish |
| Frost resistance (freeze-thaw cycling) | BS EN 12371 | No loss of flexural strength after 48 cycles |
Figures above are reference results for the range and are confirmed again on a batch basis. Certificates for the specific batch behind your order are issued alongside the commercial documents and are available on request before you place it.
Sampling
Sample before order
We do not take an order against a photograph alone. Every enquiry that proceeds to quote can be offered a physical sample cut from current stock, so a buyer can inspect colour, finish and general condition of the stone before committing.
A sample confirms colour, finish and feel; the test results above confirm the engineering figures behind them. Between the two, a specifier has both what the stone looks like and how it performs.
At the yard
In-process checks and batch testing
01
Block selection
Blocks assessed visually for fracture, colour and bedding consistency before cutting.
02
Cutting
Slabs cut to the ordered size at the yard.
03
Honing and polishing
Finish applied on-site to the ordered specification.
04
Pre-crating inspection
Visual and dimensional check for edge chipping, staining and visible fracture before a piece is wrapped.
05
Crating
Crate contents checked against the packing list before the lid is fixed.
Visual and dimensional checks at the yard run alongside independent laboratory batch testing, which is repeated on each production run rather than carried forward indefinitely from a single certificate.
Conformity
Declarations and marking
We issue a Declaration of Performance and apply UKCA marking to consignments covered by a harmonised product standard, referencing the test results above and the specific batch shipped. Certificates are provided with the commercial documents for every order and are available in advance on request.
