    44、ON The designation thermal endurance is used here to refer to the test of thermal stress in air, excluding any other influence or stress applied to the test specimens. Thermal endurance properties evaluated in different environments and/or with different stresses applied to the test specimens requir

    45、e different test procedures. In this part of IEC 60216, the study of the thermal ageing of materials is based solely on the change in certain properties resulting from a period of exposure to elevated temperature. The properties studied are always measured after the temperature has returned to ambie

    46、nt. Properties of materials change at various rates on thermal ageing. To enable comparisons to be made of the thermal ageing of different materials, the criteria for judgment depend on the type of property to be studied and its acceptable limiting value.
