Effect of Test values of brealcingloads are functions of the shape of the specimen, the manner oftesting and the speed at vhich load is applied. Comparisons shoul<not be too freely drawn between results obtained under test con-ditions. It is believed that the conclusions of the precedingparagraph are not deper^dent on test conditions for t
