IEC/TS 60034-18-33:2010描述了通过耐久性试验评估绝缘系统的程序，其中同时施加热应力和电应力。这些程序适用于交流电中使用的绝缘系统。使用成形绕组的电机。测试程序提供了参考系统和候选系统在电压和温度组合下的性能比较，这些电压和温度组合在过去被单独用于评估质量，并且被选择在合适的时间范围内和在实际极限内的应力下产生故障。候选绝缘系统的测试结果将表明它是比具有成熟服务经验的参考系统更好还是更差。这一新版相对于上一版的主要变化如下:-研究热应力和电应力之间相互作用性质的要求已被放弃；-取消了单一应力加速因子的使用；-应力水平的选择已经调整，温度现在与绝缘系统的热等级温度相关；-引入终点标准；-显示结果的简化方法。

IEC/TS 60034-18-33:2010 describes procedures for evaluation of insulation systems by endurance testing where thermal and electrical stresses are applied simultaneously. The procedures are intended for insulation systems used in a.c. electrical machines using form-wound windings. The test procedures provide a comparison of performance between reference and candidate systems at combinations of voltage and temperature which have been used separately to assess quality in the past and which are chosen to produce failures within a suitable timescale and at stresses within practical limits. The outcome of the test on the candidate insulation system will indicate whether it is better or worse than the reference system with proven service experience. The main changes of this new edition with respect to the previous one are as follows:
- the requirement to investigate the nature of interactions between thermal and electrical stresses has been abandoned;
- the use of single stress acceleration factors has been removed;
- the selection of stress levels has been adjusted and the temperatures are now related to the thermal class temperature of the insulation system;
- the introduction of end-point criteria;
- a simplified method to display results.
