Study of the stability of Charpy V-notch reference test pieces for tests at 20 °C (ERM®-FA013ba, ERM®-FA015v and ERM®-FA016ax) during long-term storage at 18°C
In the frame of the certification of the Master Batches ERM®-FA013ba, ERM®-FA015v and ERM®-FA016ax a long-term isochronous stability study was planned covering a storage period of 48 months with storage periods of 12, 24, 36 and 48 months at a storage temperature of 18 °C and using a reference temperature of 20 °C.
The results of the stability study indicate that the absolute values obtained for the different Master Batches agree within the respective uncertainties with the certified values as well as with values obtained during the certification of Secondary Batches and that there is no indication of instability of the Charpy Master Batches for a period of at least 10 years.
Moreover as the measurement uncertainty is the main contribution to the uncertainty of the certified value it is decided not to add an uncertainty contribution for stability to the certified uncertainty of the Master Batches
