Abstract: This certification report describes the certification of ERM®-FA415s, a batch of steel Charpy V-notch certified reference test pieces. This batch will serve as a Master Batch, to be used by IRMM for the certification of secondary batches. Sets of five pieces taken from a secondary batch are distributed by IRMM and its authorised distributors for the verification of pendulum impact test machines according to ISO 148-2. 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 for KV is an estimate of the mean value of the whole batch. The obtained values are shown in the table below. The associated uncertainties are standard uncertainties corresponding to a confidence level of about 68 %. The certified value is traceable to the International System of Units (SI). The certified value is valid only for strikers with a 2 mm tip radius. The certified value is valid at (20 ± 2) °C.
