The author suggested in his previous paper that the orders of resistance of steel to the propagation of brittle crack can be determined by the pressed-notch Charpy tests. The present paper shows the actual data of the van der Veen tests with 3mm and 8mm notches, from which the previous suggestion was originated. In addition, the simple theory of notch brittleness lectured by E. Orowan is referred and supplemented in order to explain the meanings of different two tests.
