This certification report describes the processing and characterisation of ERM®-FA415ab, a batch of Charpy V-notch certified reference test pieces certified for the absorbed energy (KV) for tests at 20 °C. 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. The certified value of ERM ®- FA415ab is traceable to the SI, via the SI-traceable certified value of the master batch ERM-FA415s, by testing samples of ERM ®-FA415ab and ERM ®-FA415s 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 values are valid at (20 ± 2) °C.JRC.D.2 - Standards for Innovation and sustainable Developmen
