Abstract

We developed a set of certified reference samples of solid substances with open porosity (imitators) (OPGP SO UNIIM set) GSO 11116-2018/GSO 11119-2018 in the form of ceramic cylinders based on aluminum oxide. The certified values of open porosity are determined by the method of gas pycnometry. The reference specimens are intended for the certification of the procedures of measurements and checking of the accuracy of the data of measurements of open porosity in the course of petrophysical investigations of cores and slime under the laboratory conditions. The reference materials can be used for the calibration and verification of the tools used for measuring the open porosity of rocks, as well as for the purposes of testing of measuring instruments. The complete budget of uncertainties is presented for the certified values obtained for reference materials with regard for the variations of ambient temperature in the case of their use in testing and calibration laboratories.
