This test method determines two important, related gasket properties which are Compressibility and Recovery. The short duration test is performed at room temperature. The major load is applied for 60 seconds before taking the measurement for compressibility and the measurement of recovery is taken 60 seconds after removal of the major load. Specific loads are applied to preconditioned specimens depending on the material type. This load is applied over an area defined by a penetrator to a gasket stress of 5,000 psi. The average of a minimum of three samples constitutes a test. The results are calculated as follows: Compressibility (%) = [(P - M)/P] x 100 and Recovery (%) = [(R -M)/ (P - M)] x 100
