Wood Flooring Grading and Type Test Results
Wood Flooring type test results including fire rating, slip tests, moisture content, load bearing breaking strength, and others as listed below. These are European tests which also satisfy the BS standards as well and can be compared. The chart below shows our general grading standard for all our oak wood flooring. This can be downloaded and copied and pasted to add to any specification you require.
 
The results below are product type testing results for our Amethyst, Diamond, Ruby and Sapphire Ranges of Wood Flooring. These have been carried out by the Timber Research and Development Institute Praha Notified Body No 1393 to EEC standards and for the slip test to BS7967 and were carried out by SATRA a UCAS accredited testing institute.
 
When specifying our wood flooring you should state that any substituted wood flooring should conform to the same stringent requirements to ensure that inferior products are not supplied which could compromise the integrity of the installation.
 
Essential Characteristics with EN or BS standard testing method

Moisture Content: EN 13183-1 Result = 7 %
Width permitted deviation:  EN 13647 Result -0.01mm
Reaction to Fire: EN 13501-1 Result Dn-s1
Release of Formaldehyde: EN 717-1 Result 0.014 mg/m3
Breaking Strength: EN1533 Result 22.7 kN
Slipperiness: CEN/TS 15676 Result USRV 58
Thermal Conductivity: EN ISO 10456 and EN ISO 12664 Result 0.15 W/(mk) 
Load Bearing: complies with BS 6399-1:1996 Table 1 section 3 for load bearing
 
Slip test using the pendulum testers method BS7967 part 2 classification the slip resistance group guidelines Slip Potential (PTV) values are as follows:
 
High slip potential 0 – 24     Moderate slip potential 25 – 35     Low slip potential 36+
 
As can be seen from the results below of our type tested products our floors have very low slip potential. 
 
Type of Board:  Natural Oiled Wood Flooring Oak              Dry overall slip measurement  66
                                                                                       Wet (water) slip measurement  29 
  
                          Lacquered Wood Flooring                         Dry overall slip measurement  61

All you then need to do is to include the product code which will define the size, finish colour and construction. You can access the Architects full Specification document for full details of each product that you can copy and paste. There are also our other tests and these are listed here. We do not use any Pentachlorophenol containing materials and download versions of everything on this page are in the links below:
