UNE-EN IEC 60216-3:2021

This part of IEC 60216 specifies the calculation procedures to be used for deriving thermalendurance characteristics from experimental data obtained in accordance with the instructionsof IEC 60216-1 and IEC 60216-2, using fixed ageing temperatures and variable ageing times.The experimental data may be obtained using non-destructive, destructive or proof tests. Dataobtained from non-destructive or proof tests may be incomplete, in that measurement of timestaken to reach the endpoint may have been terminated at some point after the median timebut before all specimens have reached end-point.The procedures are illustrated by worked examples, and suitable computer programs arerecommended to facilitate the calculations.
