Abstract

Charpy V reference test pieces are required by standards EN 10045-2 and ISO DIS 442 for the indirect verification of pendulum impact testing machines. Based on an agreement between Aubert & Duval, LNE, ETCA and FFA, production of such test pieces has begun in France. A preliminary study, made with an experimental batch, has shown that these test pieces are equivalent to the BCR test pieces. This trial production allowed us to define the manufacturing and calibration conditions for the industrial production of Charpy V reference test pieces. Three levels of impact energy are available. The main features of this production are presented.
