Scope: This part of GB/T 11026 specifies the general aging conditions and procedures used to obtain heat-resistant characteristic parameters, and gives guidance on the use of detailed procedures and guidelines in other parts of this standard. Simplified procedures and the conditions under which they can be used are also given. Although this standard was originally developed for use with electrical insulating materials and simple combinations thereof, these procedures are considered to be of more general applicability and to be widely applicable to the evaluation of materials other than electrical insulating materials. In applying this standard, it is assumed that there is an almost linear relationship (Arrhenius relationship) between the logarithm of the time required to cause a predetermined change in performance and the corresponding reciprocal of the absolute temperature. For the effective application of this standard, no transitions, especially first-order transitions, should occur within the temperature range under study. In all other parts of this standard, the term "insulating material" is still used to mean "insulating material and simple combinations thereof".
