Abstract
Methods of determining an apparent density of a sealant used to encase a material specimen during liquid displacement evaluations include: (a) providing a plurality of material reference samples in an assortment of dimensional ranges and geometrical shapes; (b) obtaining a sealant used to encase material specimens undergoing liquid displacement evaluations; and (c) establishing a plurality of apparent density values for the sealant, one apparent density value for each of the plurality of reference samples identified in the providing step.
