For yield strength the yield, ReL, is used when yielding occurs, otherwise the 0,2 % proof strength, Rp0,2, is used. b
Gauge length is equal to five times the test specimen diameter.

Three specimen must reach average impact energy of 47J, only one of them min 32J .
Among five specimen the highest and the lowest values aren’t taken be in account; the average of other thee must be 27 J, only one them can be min 20J. .
