In analyzing fire test data it has been customary to assume that for concrete masonry units of different geometries but made from the same mix a fire endurance versus equivalent thickness plot on log-log paper is approximately a straight line. It has since been proved that this assumption is not necessarily correct, yet one can expect that this practice of correlating fire test data will go on for some time to come. It is of some practical importance, therefore, to have a simple test method available for the reasonably accurate assessment of the equivalent thickness of hollow masonry units.
