Abstract: The article deals with data of research for development of certified reference materials set for opened porosity of solid substances and materials (imitators) (OPGP SO UNIIM set) GSO 11116-2018/GSO 11119-2018. The certified values of open porosity are determined using a gas pycnometer. Certified reference materials are intended for certification of measurement techniques and control of the accuracy of open porosity measurement results for petrophysical studies of core. Certified reference materials can be used for calibration, verification of o...
