IEC 60437 is an international standard for "Radio disturbance characteristics - Limits and methods of measurement". Here's a potential feature:
Insulators must be completely clean, dry, and free of dust or grease before testing begins.
Understanding IEC 60437: The Definitive Guide to Radio Interference Tests on High-Voltage Insulators
: Measurements are strictly focused on high-frequency noise. The baseline testing frequencies are fixed at 0.5 MHz or 1.0 MHz . However, alternative testing frequencies between 0.5 MHz and 2.0 MHz are permissible under the standard's guidelines. iec 60437 pdf
Provides uniform testing methods across different laboratories worldwide.

The 2023 revision introduced several significant changes over the previous 1997 version: iTeh Standards Expanded Scope: IEC 60437 is an international standard for "Radio
Measurement apparatus conforms to the specifications detailed in CISPR 16-1, ensuring consistent radio disturbance measurements. 2. Procedure
Atmospheric conditions significantly alter corona inception voltages. IEC 60437 requires meticulous recording of: Ambient temperature Air pressure Relative humidity
The voltage is raised smoothly until a distinct radio interference signal is detected by the receiver (Inception Voltage). The baseline testing frequencies are fixed at 0
If you need help digging into the engineering specifics of this test, please let me know: Are you focusing on or composite insulators? What is the voltage class of your project?
The standard details how to evaluate the radio noise emission levels of insulators when they are subjected to elevated voltages under controlled environments.
