Abstract

This certification report describes the processing and characterisation of ERM-FA415i, 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 155.1 J. The associated uncertainty (4.6 J, k = 2 corresponding to a confidence level of about 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 [3] and ISO 148 [4], via the corresponding Master Batch ERM-FA415b of the same nominal absorbed energy (150 J). The certified value is valid only for impact hammers with a 2 mm striker tip radius.
