IEC 60216-3:2021 is available as IEC 60216-3:2021 RLV<\/span> which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60216-3:2021 specifies the calculation procedures used for deriving thermal endurance characteristics from experimental data obtained in accordance with the instructions of IEC 60216-1 and IEC 60216-2, using fixed ageing temperatures and variable ageing times. The experimental data can be obtained using non-destructive, destructive or proof tests. Data obtained from non-destructive or proof tests can be incomplete, in that it is possible that measurement of times taken to reach the end-point will have been terminated at some point after the median time but before all specimens have reached end-point. The procedures are illustrated by worked examples, and suitable computer programs are recommended to facilitate the calculations. This edition includes the following significant technical changes with respect to the previous edition: – a new computer program has been included; – Annex E ” has been completely reworked.<\/p>\n
