Abstract

This certification report describes the processing and characterisation of ERM-FA015t, 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 80.4 J. The associated uncertainty (1.9 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 [3] and ISO 148 [4], via the corresponding Master Batch ERM-FA015o of the same nominal absorbed energy (80 J). ERM-FA015t has been accepted as European Reference Material (ERM) after successful peer evaluation by the partners of the European Reference Materials consortium.
