Scope: This standard 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 1000 V and a frequency not greater than 100 Hz. It may also be regarded as a provisional standard for insulators for use on d.c. systems. IEC Publication 438, Tests and Dimensions for High-voltage D.C. Insulators (report), gives general guidance for those insulators. When considering hollow insulators, IEC Publication 233, Tests on Hollow Insulators for Use in Electrical Equipment, shall also be taken into account. This standard does not apply to indoor post insulators of organic material which will be covered by a future IEC publication, Tests on Indoor Post Insulators of Organic Material for Systems with Nominal Voltages Greater than 1000 V up to but not including 300 kV. Note. — This standard does not include artificial pollution and radio-interference tests. These subjects and relevant test methods are referred to in the following I EC reports. These reports are only issued for information and as a means of gainingexperience in these subjects. Publication 507: Artificial Pollution Tests on High-voltage Insulators to Be Used on A.C. Systems. Publication 437: Radio Interference Test on High-voltage Insulators.
