FIELD: measurement technology. SUBSTANCE: spherical indenter is penetrated into material to be tested. Diameter of indentation mark and plastic hardness are recorded. Stress at indentation mark center is estimated, load applied to indenter is measured, and yield strength is calculated using formula given in specification. EFFECT: test run duration cut, measurement accuracy increased. 1 tbl
