Certification of Charpy V-notch test pieces of 120 J nominal absorbed energy : certified reference material ERM-FA016ar : certification report

This certification report describes the processing and characterisation of ERM-FA016ar, a batch of Charpy V certified reference test pieces. Sets of five of these test pieces are used for the verification of impact pendulums according to EN 10045-2 (Charpy impact test on metallic materials, Part 2. Method for the verification of impact testing machines) or to ISO 148-2 (Metallic materials - Charpy pendulum impact test - Part 2: Verification of test machines). Measurements were performed to determine the certified value for absorbed energy (= energy required to break a V-notched test piece when tested using a pendulum impact testing machine). The certified value (120.1 J) and uncertainty (3.4 J, k = 2 corresponding with a confidence level of 95 %) pertain to the expected mean of a set of five test pieces. The certified value is traceable to the Charpy impact test method as described in EN 10045-1 and ISO 148, via the corresponding Master Batch ERM-FA016c of the same nominal absorbed energy (120 J).
