dc.description.abstractThis certification report describes the processing and characterisation of ERM®-FA013bf, 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 (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 certified value for KV (= energy required to break a V-notched test piece using a pendulum impact test machine) is 27.7 J. The associated uncertainty (1.1 J, k = 2 corresponding to a confidence level of about 95 %) is calculated for the mean of a set of five test pieces. 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 value of ERM®-FA013bf 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®-FA013bf 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.en_GB
