The certification of the absorbed energy (150 J nominal) of Charpy V-notch reference test pieces for tests at 20 °C: ERM ®-FA415z
This certification report describes the processing and characterisation of ERM®-FA415z, a batch of Charpy V-notch reference test pieces certified for the absorbed energy (KV) for tests at 20 °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 [1]).
The measurand KV is procedurally defined and refers to the impact energy required to break a V-notch test piece of standardised dimensions, as defined in ISO 148-1 [2]. The certified value of ERM- FA415z is traceable to the SI, via the SI-traceable certified value of the master batch ERM-FA415s, by testing samples of ERM-FA415z and ERM-FA415s 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.
