DESIGNED FOR
Calibration of measuring instruments for open porosity of solids and materials and other types of metrological control. Reference materials саn bе used for verification and testing for type approval of measuring instruments for open porosity of solids and materials, in case the metrological characteristics of reference materials meet the established requirements.
INDUSTRIAL APPLICATION
State regulation: when performing state accounting operations and accounting of quantity of energy resources.
SPHERES OF APPLICATION
Scientific research geology, oil and oil refining industry.
