Three samples of three-ply laminated Oak Hardwood flooring (nominal thickness 13.5mm) were tested for abrasion resistance. The Abrasion Resistance tests were based on procedures of the American Society for Testing and Materials ASTM D4060 Standard using the standardized “Tabor Abrasion” machine. Each of the two CS-17 Taber Abrasive wheels used in the test were weighted to 500 grams total for the two wheels. Samples were prepared as received to a dimension of 13.5mm x 101.6mm x 101.6mm. The abrasive wheels wore a circular path through the surface identified as a ‘circle’. Abrasion resistance was determined by the number of revolutions or cycles that were counted and the depth of the wear through the surface coating.

There are described as follows:
- Initial Wear-through-First wear-through at any one point of the coating to the substrate.
- Final Wear-through-Complete coating wear-through at all points of the test circle.
- Average Wear-through-Average of initial and Final coating wear-through.
- Coating thickness-Average depth of the coating in four quadrants of the circle.
- Wear Rate-No, of cycles or revolutions per 0.1mm.
