適用范圍：This standard applies to insulators of ceramic material or glass for use on a.c. overhead power and traction lines with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz.It also applies to insulators for use on d.c. overhead electric traction lines.This standard applies to string insulator units, insulator strings, insulator sets and rigid overhead line insulators and to insulators of similar design when used in sub-stations.It does not apply to insulators forming parts of electrical apparatus or to parts used in their construction or to post insulators which are covered by I E C Publication 168: Tests on Indoor and Outdoor Post Insulators of Ceramic Material or Glass for Systems with Nominal Voltages Greater than 1 000 V.It may be regarded as a provisional standard for insulators for use on d.c. overhead power lines. I E C Publication 438: Tests and Dimensions for High-voltage D.C. Insulators (report), gives general guidance for those insulators.Note. — This standard does not include artificial pollution, radio-interference and thermal-mechanical tests. These subjects and relevant test methods are under consideration and are dealt with in the following I E C publications. These publications are issued for information only and as a means of gaining experience in these subjects.Publication 437: Radio Interference Test on High-voltage Insulators.Publication 507: Artificial Pollution Tests on High-voltage Insulators to be Used on A.C. Systems.Publication 575: Thermal-mechanical Performance Test and Mechanical Performance Test on String Insulator Units.
