Abstract： In order to study the problem of eccentric compression of specimens during the compressive strength test ofrefractory materials，the method of metrological testing was used to solve practical problems in the inspection and testing industry.Eccentric compression tests were conducted through specimens and standard dynamometer，and the testresultswerecalculatedandanalyzed.Acomprehensive conclusionwasobtained，and these conclusions were theoreticallyand experimentally verified.Itis of promotional significance forproviding asolution to te problemof test datausing metrological testing methods forcompressivestrength testingintherefractorymaterialsindustryas wellas compressive andflexural strength testing in the inspectionand testing industry and the building materials industry.
