Abstract: This certification report describes the processing and characterisation of ERP-FA415i, a batch of Charpy V-notch certified reference test pieces. Sets of five of these test pieces are used for the vertification of pendulum impact test machines according to En 10045-2 or according to ISO 148-2. The certified value for KV (= energy required to break a V-notched test piece using a pendulum impact test machine) is 155.1 J. The associated uncertainty (4.6 J, k=2 corresponding to a confidence level of about 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-FA415b of the same nominal absorbed energy (150J). The certified value is valid only for impact hammers with a 2 mm striker tip radius.
