This technical data sheet was initially compiled by the Building Research 
Establishment (BRE) at the request of Albion Stone and is updated by Albion Stone 
to incorporate current test results.  The 1514 tests have been carried out from 2006 
in accordance with current European standards by the BRE and Sandbergs on 
Albion Stone's behalf, or by other accredited testing houses. The early test data that 
pre-dates the introduction of Euro-codes has been included providing the test 
methods were very similar. The work carried out by the BRE on this technical data 
sheet has been undertaken as a paid commission and does not represent an 
endorsement of the stone by the BRE. 
This data includes the Lowest and Highest Expected Values (LEV & HEV) using the 
statistical calculations from the Euro-codes. We are confident that these results give 
a good indication of the stones value, but as it is a natural material, we, like other 
stone producers, are unable to guarantee individual results for specific stones.  
Section 5.6 in the BS8298 part 2 & 4 set out the calculation for the factor of safety.  
Table 4 shows the components for this calculation and Albion Stone are happy to 
assist with interpretation of our data.
