BS EN 12390-3:2002

This European Standard, a part of the BS EN 12390 series, specifies a method for the determination of the compressive strength of test specimens of hardened concrete.

Specimens are loaded to failure in a compression testing machine conforming to BS EN 12390-4. The maximum load sustained by the specimen is recorded and the compressive strength of the concrete is calculated.

Annexes to this standard provide requirements on the adjustment of test specimens and a procedure for testing specimens with dimensions outside the tolerances of the designated sizes of BS EN 12390-1.
