The document builds upon the general principles established in IEC/TS 60815-1

This document provides a systematic framework for engineers to select and size insulators—such as porcelain or glass—based on the specific environmental pollution levels they will face in service. Core Purpose and Scope iec 60815-2 pdf

In high-voltage engineering, pollution is a primary cause of insulator flashover, which can lead to catastrophic grid failures. When salt, dust, or industrial particulates accumulate on an insulator surface and become moist (due to fog or light rain), they form a conductive layer. IEC 60815-2 provides the methodology to determine the "Site Pollution Severity" (SPS) and subsequently choose an insulator design—specifically its —that can withstand these environmental stresses.
