Preskus, pri katerem cev razpade na tri ali več delov, ki so v nekaterih primerih lahko med seboj povezani s tankimi trakovi kovine, kakor je prikazano na sliki 2, se ovrednoti kot preskus, pri katerem je prišlo do eksplozije.
A test resulting in the fragmentation of the tube into three or more pieces, which in some cases may be connected to each other by narrow strips of metal as illustrated in figure 2, is evaluated as giving an explosion.
