Certification of Charpy V-notch Reference Test Pieces of 30 J Nominal Absorbed Energy (ERM-FA013bd)

This certification report describes the processing and characterisation of ERM®-FA013bd, 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 26.9 J. The associated uncertainty (1.0 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 in EN 10045-1 and ISO 148. The certified value of ERM®-FA013bd 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®-FA013bd in repeatability conditions on an impact pendulum verified with SI-traceably calibrated toolsJRC.DDG.D.2-Reference material
