指导进行绝缘协调研究，提出国际公认的建议 -用于电气系统的数值建模，以及 -用于实施适用于使用数值程序的确定性和概率性方法。 其目的是提供方法、建模和示例方面的信息，允许应用IEC 60071-2中提出的方法，以及选择IEC 60071中定义的设备或装置的绝缘水平- 1.

Gives guidance on conducting insulation co-ordination studies which propose internationally recognized recommendations - for the numerical modelling of electrical systems, and - for the implementation of deterministic and probabilistic methods adapted to the use of numerical programmes. Its object is to give information in terms of methods, modelling and examples, allowing for the application of the approaches presented in IEC 60071-2, and for the selection of insulation levels of equipment or installations, as defined in IEC 60071-1.
