適用范圍：This part of IEC 60216 specifies the experimental and calculation procedures to be used forderiving the relative thermal endurance index of a material from experimental data obtained inaccordance with the instructions of IEC 60216-1 and IEC 60216-2. The calculation proceduresare supplementary to those of IEC 60216-3.Guidance is also given for assessment of thermal ageing after a single fixed time andtemperature, without extrapolation.The experimental data may in principle be obtained using destructive, non-destructive or prooftests, although destructive tests have been much more extensively employed. Data obtainedfrom non-destructive or proof tests may be “censored”, in that measurement of times taken toreach the endpoint may have been terminated at some point after the median time but beforeall specimens have reached end-point (see IEC 60216-1).Guidance is given for preliminary assignment of a thermal class for an insulating material,based upon the thermal ageing performance.The calculation procedures of this standard also apply to the determination of the thermalclass of an electrical insulation system when the thermal stress is the prevailing ageing factor.
