This certification report describes the processing and characterisation of ERM®-FA015x and ERM®-FA015y, two batches 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 (Charpy impact test on metallic materials, Part 2. Method for the verification of impact testing machines) or according to ISO 148-2 (Metallic materials - Charpy pendulum impact test – Part 2: Verification of test machines). 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 148-1. The certified values of ERM®- FA015x and ERM®-FA015y are made traceable to the SI, via the SI-traceable certified value of the master batch ERM®-FA015v, by testing samples of ERM®- FA015x and ERM®-FA015y and ERM®-FA015v 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.
