Abstract: This certification report describes the processing and characterisation of ERM®-FA013bg and ERM®-FA013bh, 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 [1]) or according to ISO 148-2 (Metallic materials - Charpy pendulum impact test - Part 2: Verification of test machines [2]). 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 [3] and ISO 148-1 [4]. The certified values of ERM®- FA013bg and ERM®-FA013bh are made traceable to the SI, via the SI-traceable certified value of the master batch ERM®-FA013ba, by testing samples of ERM®- FA013bg and ERM®-FA013bh and ERM®-FA013ba 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.
