Abstract: This certification report describes the processing and characterisation of ERM-FA016at, a batch of Charpy V-notch certified reference test pieces. Sets of five of these test pieces are used for the verification of pendulum impact test machines according to EN 10045-2 of according to ISO 148-2. The certified value of KV (absorbed energy = energy required to break a V-notched test piece using a pendulum impact test machine) is 126.3 J. The associated expanded uncertainty (3.6 J, k = 2 corresponding to a confidence level of 95 %) is calculated for the mean of a set of five test pieces. The certified value is traceable to the Charpy impact test method as described in EN 10045 1 and ISO 148, via the corresponding master batch ERM-FA016c of the same nominal absorbed energy (120 J).
