Abstract

This certification report describes the processing and characterisation of ERM-FA016as, 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) or according to ISO 148-2 (Metallic materials - Charpy pendulum impact test, Part 2: Verification of test machines). The certified value for KV (= energy required to break a V-notched test piece using a pendulum impact test machine) is 123.9 J. The associated uncertainty (3.7 J, k = 2 corresponding to a confidence level of 95 %) is calculated for the 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).
