What is BS EN 1097‑2 about?
BS EN 1097‑2 is the second part of the BS EN 1097 series of documents that 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 determining the resistance to fragmentation of coarse aggregates (main text) and aggregates for railway ballast.
For other purposes, in particular factory production control, other methods are possible provided that an appropriate working relationship with the reference method has been established.
NOTE: BS EN 1097‑2 applies to natural, manufactured or recycled aggregates used in building and civil engineering.
Who is BS EN 1097‑2 for?
BS EN 1097‑2 on the determination of the resistance of aggregates is useful for:
- Builders
- Civil engineers
- Manufacturers of cement and concrete
Why should you use BS EN 1097‑2?
Fragmentation resistance (FR) test using Los-Angele’s apparatus is used to identify the strength of aggregate.
BS EN 1097‑2 gives additional apparatus requirements for the determination of resistance to fragmentation by the Los Angeles test method and impact test method describing the principle, test methods, and calculations. Also, gives a determination of resistance to fragmentation of aggregates for railway ballast.
Overall, these test methods let you manufacture the aggregates to resist the fragmentation of aggregates to ensure the strength and durability of aggregates while used in construction.
