IEC 60587:2022描述了两种测试方法，用于评估在工频（45 Hz至65 Hz）的恶劣环境条件下使用的电绝缘材料，通过使用液体污染物和斜面样本评估耐跟踪性和耐腐蚀性。这两种方法是: -方法1:在恒定电压下测试， -方法2:在逐步增加的电压下进行测试。 方法1是最广泛使用的方法，因为不太需要连续检查。 测试条件旨在加速效果的产生，但不能再现使用中遇到的所有条件。 与上一版相比，此版本包括以下重大技术变更: a)已经实现了对实验方法的改进描述；b)已经实施了对试样制备的改进描述； c)增加了对电极材料和电极质量的更详细描述； d）根据测试方法2（逐步跟踪电压）进行测试的评估标准B（跟踪长度）已被删除，因为它不适用。

IEC 60587:2022 describes two test methods for the evaluation of electrical insulating materials for use under severe ambient conditions at power frequencies (45 Hz to 65 Hz) by the evaluation of the resistance to tracking and erosion, using a liquid contaminant and inclined plane specimens. The two methods are:
- Method 1: test at constant voltage,
- Method 2: test at stepwise increased voltage.
Method 1 is the most widely used method as there is less need for continual inspection.
The test conditions are designed to accelerate the production of the effects, but do not reproduce all the conditions encountered in service.
This edition includes the following significant technical changes with respect to the previous edition:
a) an improved description of the experimental methods has been implemented;
b) an improved description of the preparation of the test specimens has been implemented;
c) a more detailed description of the electrode material and of the electrode quality has been added;
d) evaluation criterion B (track length) has been removed for testing according to test method 2 (stepwise tracking voltage) as it is not applicable.
