Measurement uncertainty in testing of uniaxial compressive strength and deformability of rock samples

This paper describes instrumental measurement uncertainties and their influence on the result obtained from determination of rock samples uniaxial compressive strength and deformability. The interdependence of uncertainty contribution is analyzed and guides for improving measurement uncertainty are given. The achieved uncertainties are compared to typical uncertainties in the determination of concrete and metallic materials deformability.
