Abstract: This certification report describes the processing and characterisation of ERM®-FA013bc, 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 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 26.5 J. The associated uncertainty (0.9 J, k = 2 corresponding to a confidence level of 95 %) is calculated for the mean of a set of five test pieces. The absorbed energy (KV) is procedurally defined and refers to the impact energy required to break a V-notched bar of standardised dimensions, as defined in EN 10045-1 and ISO 148. The certified value of ERM®-FA013bc is traceable to the SI, via the SI-traceable certified value of the master batch ERM®-FA013ba, by testing samples of ERM®-FA013ba and ERM®-FA013bc in repeatability conditions on an impact pendulum verified and calibrated with SI-traceably calibrated tools.
