Abstract
Method of non-destructively determining response pressure of a reversible rupture disc which includes: measuring resonance frequencies of lower vibration modes of the reversible rupture disc at varying measuring pressures below the response pressure of the reversible rupture disc; and extrapolating from the resonance frequencies of each of the vibration modes as a function of the measuring pressure, that pressure at which the resonance frequency of the respective vibration mode becomes zero, the lowest pressure at which one of the vibration modes would have zero resonance frequency being the lowest response pressure of the reversible rupture disc; and apparatus for performing the method.
