The present method for evaluating the functioning quality of benite strands is the closed bomb test for quickness. A non-destructive, faster and simpler porosity test is described which correlates very closely with the quickness test. The results obtained by each test from twenty lots of benite representing satisfactory and unsatisfactory quality were compared. A highly significant correlation coefficient of 0.92 was found. The regression equation with associated confidence limits was derived. This equation, which relates quickness and porosity results, can be used to predict one value from the other.
