IEC 61857-32:2019系列专注于需要纳入其他可能因素以评估对电绝缘系统（EIS）性能的任何影响的应用。多因素评估是设计和实施的最复杂的项目类型。需要明确的指南，为本文件的用户提供统一的方法和分析测试结果的方法。 本文件适用于应力是IEC 60505中确定的其他影响因素的某种组合的应用。在每个测试循环的诊断部分期间施加多因素应力。 其他影响因素或多因素压力的几个例子是: -高振动； -浸没在油、水或溶液中； -高于参考EIS的测试电压的电压； -冷休克温度降低。

IEC 61857-32:2019 series is focused on applications where other possible factors need to be incorporated to evaluate any influence on the performance of the electrical insulation system (EIS). Multi-factor evaluation is the most complex type of project to design and conduct. Clear guidelines are needed to give the user of this document a uniform approach and a method to analyse the test results.
This document is for applications where the stresses are some combination of other factors of influence identified in IEC 60505. The multi-factor stresses are applied during the diagnostic portion of each test cycle.
A few examples of other factors of influence or multi-factor stresses are:
– high vibration;
– submersion in oils, water, or solutions;
– voltage higher than the test voltage of the reference EIS;
– decreased cold shock temperature.
