For thicknesses between 6 11.9mm subsize Charpy V-Specimens are used. The specified minimum value is then proportional to the cross-sectional area of the test specimen. Compared to a full size specimen (10*10mm). Impact testing according to ISO EN 148 per heat and thickness group. Average of three tests. Single value minimum 70% of specified average. Impact test is performed from 6 mm .
