EN 1097-9:2014 Tests for mechanical and physical properties of aggregates - Part 9: Determination of the resistance to wear by abrasion from studded tyres - Nordic test
This European Standard describes the reference method, used for type testing and in case of dispute, for determination of the resistance of coarse aggregate to wear by abrasion from studded tyres. For other purposes, in particular factory production control, other methods may be used, provided that an appropriate working relationship with the reference method has been established. The test is applicable to aggregates with a size fraction of 11,2 mm to 16 mm. NOTE An alternative size fraction 8/11,2 mm for different end uses is given in Annex A.
