Abstract: This certification report describes the processing and characterisation of ERM®-FA415v, a batch of Charpy V-notch certified reference test pieces certified for the absorbed energy (KV). Sets of five of these test pieces are used for the verification of pendulum impact test machines according to ISO 148-2 (Metallic materials - Charpy pendulum impact test - Part 2: Verification of testing machines). The absorbed energy (KV) is procedurally defined and refers to the impact energy required to break a V-notched test piece of standardised dimensions, as defined in ISO 148-1 [2]. The certified value of ERM®- FA415v is made traceable to the SI, via the SI-traceable certified value of the master batch ERM®-FA415b, by testing samples of ERM®- FA415v and ERM®-FA415b under repeatability conditions on an impact pendulum verified and calibrated with SI-traceably calibrated tools. The certified value is valid only for strikers with a 2 mm tip radius. The certified value is valid at (20 ± 2) °C.
