METHOD OF DETERMINATION OF DEGREE OF CLOSED VOLUME SEALING Russian patent published in 1998 - IPC

Abstract RU 2106612 C1

FIELD: instrumentation engineering; mechanical engineering. SUBSTANCE: when testing the closed volumes by accumulation method at atmospheric pressure, concentration of oxygen in accumulator is measured. Then limiting hydrocarbon is burned, and oxygen concentration is measured again. Leakage value of limiting hydrocarbon is determined by difference of measured oxygen concentrations, and then sealing coefficient is calculated. EFFECT: higher test results. 1 dwg
