The certification of the absorbed energy (30 J nominal) of Charpy V-notch reference test pieces for tests at 20 and at 0 °C: ERM®-FA013bk
This certification report describes the processing and characterisation of ERM®-FA013bk, a batch of Charpy V-notch certified reference test pieces certified for the absorbed energy (KV) for tests at 20 and at 0 °C. Sets of five of these test pieces are used for the verification of pendulum impact test machines according to ISO 148-2 (Metallic materials - Charpy pendulum impact test – Part 2: Verification of testing machines).
The absorbed energy (KV) is procedurally defined and refers to the impact energy required to break a V-notched test piece of standardised dimensions, as defined in ISO 148-1. The certified value of ERM- FA013bk is traceable to the SI, via the SI-traceable certified value of the master batches ERM-FA013ba and ERM-FA013ay, by testing samples of ERM- FA013bk and ERM-FA013ba and ERM-FA013bk and ERM-FA013ay respectively, 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 values are valid at (20 ± 2) °C and (0 ± 2) °C respectively.
