适用于标称电压大于1000 V、频率不大于100 Hz的交流电气装置或设备的室内和室外用陶瓷材料或玻璃支柱绝缘子和支柱绝缘子单元。 笔记: -也可被视为直流系统用绝缘子的临时标准，见IEC 60438。 -考虑空心绝缘子时，参见IEC 60233。 -有机材料室内支柱绝缘子的试验将在未来的出版物中介绍:标称电压大于1000 V至300 kV（不包括300 kV）系统的有机材料室内支柱绝缘子的试验。 -有关人工污染和无线电干扰试验，请参见IEC 60437和60507。 -有关绝缘子特性的数值以及特定运行条件下绝缘子的选择，请参见 IEC 60273。

Applies to post insulators and post insulator units of ceramic material or glass for indoor and outdoor service in electrical installations or equipment operating on alternating current with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. Notes: -May also be regarded as a provisional standard for insulators for use on d.c. systems, see IEC 60438. -When considering hollow insulators, see IEC 60233. -Tests on indoor post insulators of organic material will be covered by a future publication: Tests on indoor post insulators of organic material for systems with nominal voltages greater than 1 000 V up to but not including 300 kV. -For artificial pollution and radio-interference tests, see IEC 60437 and 60507. -For numerical values for insulator characteristics and for selection of insulators for specific operating conditions, see IEC 60273.
