is an international standard titled: "Insulators for overhead lines with a nominal voltage greater than 1000 V – Radio interference test procedure for a.c. systems."

Now explicitly covers composite station post and composite hollow-core station post insulators. iec 60437 pdf

: Tests are typically conducted at 0.5 MHz or 1.0 MHz . The standard allows for alternative frequencies between 0.5 MHz and 2.0 MHz if agreed upon by the purchaser and manufacturer. The standard allows for alternative frequencies between 0

: The newest revision introduces a sample test fast procedure to streamline verification during production. Key Updates in the 2023 Edition This includes the configuration of the test circuit,

The standard details the specific laboratory conditions required for accurate testing. This includes the configuration of the test circuit, the atmospheric conditions (temperature, pressure, and humidity), and the background noise levels allowed during measurement. A typical RIV test involves applying a power-frequency voltage to the insulator and measuring the resulting high-frequency noise using a specialized radio interference meter. The IEC 60437 PDF outlines how to calibrate these instruments and how to arrange the test object to simulate real-world installation as closely as possible.
