The standard provides laboratory procedures for performing radio interference (RI) tests on high-voltage insulators . The current version is IEC 60437:2023 (Edition 3.0), which superseded the 1997 edition. Core Standard Features Overview of IEC 60437 Establishes a standardized method
The execution of an IEC 60437 test involves a deliberate voltage-application profile designed to eliminate "hysteresis" or transient surface conditions on the insulator.
The standard has evolved through several editions to include modern insulator types and refined testing methods:
You can find the latest edition on the IEC Webstore or through national standards bodies like BSI or ANSI.
