UTR-0400 is used for uniaxial compressive strength tests of rock core specimens with Ø47,6 mm to Ø63,5 mm. Supplied with 2 pcs. 32 mm and 1 pcs. 20 mm distance pieces
The radius of the upper and lower jaws of UTR-0422 and UTR-0424 are designed in accordance with the sample diameter.and they are supplied with spherical seat with a 25 mm half ball bearing acc.to ISRM.
UTR-0426 is designed for testing splitting tensile strength of rock specimens with diameter of 54,7 mm and 63,5 mm and supplied with a distance piece acc. to ASTM.
WARNING : Many rock types fail in a violent manner when loaded to failure in compression. For protecting the operator from this danger, the specimens can be wrapped with a protective shield before the compression test.
