电气绝缘材料 耐热性 第1部分：老化规程和试验结果的评价

[中文适用范围]： IEC 60216 的这一部分规定了用于推导热耐久性特性的一般老化条件和程序，并为使用该标准其他部分中的详细说明和指南提供了指导。还给出了简化的程序以及可以使用这些程序的条件。尽管最初开发用于电绝缘材料和此类材料的简单组合，但这些程序被认为具有更普遍的适用性，并广泛用于评估不打算用作电绝缘的材料。在本标准的应用中，假设引起预定性质变化所需的时间的对数与相应的绝对温度的倒数之间存在实际上的线性关系（阿累尼乌斯关系）。为了有效应用该标准，在研究的温度范围内不应发生转变，特别是不应发生一级转变。在本标准的其余部分中，术语“绝缘材料”始终表示“绝缘材料和此类材料的简单组合”。 [外文原描述]： Specifies the general ageing conditions and procedures to be used for deriving thermal endurance characteristics and gives guidance in using the detailed instructions and guidelines in the other parts of the standard. Simplified procedures are also given, with the conditions under which these procedures may be used. Although originally developed for use with electrical insulating materials and simple combinations of such materials, the procedures are considered to be of more general applicability and are widely used in the assessment of materials not intended for use as electrical insulation. In the application of this standard, it is assumed that a practically linear relationship exists between the logarithm of the time required to cause the predeter-mined property change and the reciprocal of the corresponding absolute temperature (Arrhenius relationship). For the valid application of the standard, no transition, in particular no first-order transition, should occur in the temperature range under study.
