EN 1926 Natural Stone Test Methods - Standard Test for Determination of Uniaxial Compressive Strength

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 1926 testing. This European standard specifies a method for determining the uniaxial compressive strength of natural stone.

The samples are laid and centered on the plate of a testing machine after mechanical preparation of the surfaces or, if necessary, sealed. An evenly distributed load is applied and increased continuously until failure occurs.

The faces on which the load will be applied shall be flat with a tolerance of 100 mm per 0,1 mm, and the upper surface shall lie between two parallel planes parallel to the lower surface and not more than 1 mm apart. For every 100 mm, the edges of the sample should be smooth and free of sudden irregularities and should be flat within 0,3 mm along the entire length of the sample.

The axis of the sample must be perpendicular to the planes of anisotropy, e.g. If a test with a loading orientation parallel to the anisotropy planes is required, another set of samples with the same dimensional characteristics should be prepared.

Each sample will be prepared from a separate armor stone. The test specimens shall be cubes with sides of (50 ± 5) mm or right circular cylinders of diameter and height equal to (50 ± 5) mm. For pieces of armor stone with a compressive strength of 40 MPa and less, the use of cubes with sides of (70 ± 7) mm or right circular cylinders with a diameter and height of (70 ± 7) mm is allowed.
