The goes beyond simple tables. It instructs engineers to apply correction factors for:

is the international technical specification that provides definitive guidelines for selecting and dimensioning ceramic and glass insulators for high-voltage AC systems operating in polluted environments . This standard is a critical companion to IEC TS 60815-1 , which establishes the general principles of pollution management for the entire series. Scope and Application of IEC 60815-2

Guidelines on how to utilize laboratory artificial pollution tests to verify custom insulator profiles.

: The method for converting from the RUSCD of a reference insulator to the USCD of a candidate insulator has been updated and clarified. Correction factors for altitude, diameter, shed profile, and the number of parallel insulators have been introduced or revised. iec 60815-2 pdf

The process involves:

: The standard moves away from older "rule of thumb" measurements. It utilizes the USCD, which is the total creepage distance divided by the highest operating voltage, to provide a precise requirement for the insulator’s length and surface area. Impact on Grid Reliability

: Severe industrial pollution, desert areas with conductive dust, or extreme coastal locations. The goes beyond simple tables

: Unlike generic guidelines, Part 2 provides detailed analysis of porcelain and glass shapes. It evaluates how different "shed" profiles (the disc-like parts of an insulator) perform under specific types of pollution, such as desert sand versus coastal salt spray.
