Tests for mechanical and physical properties of aggregates - Part 2: Methods for the determination of resistance to fragmentation
The standard describes the reference method, the Los Angeles test, used for type testing and in case of dispute (and an alternative method, the impact test) for the determination of the resistance to fragmentation of coarse aggregates (main text) and of railway ballast aggregates (Annex A). For other purposes, in particular factory production control, other test methods may be used provided that their comparability with the reference method has been established. The standard applies to natural, manufactured or recycled aggregates used in building and civil engineering.
