The use of IEC 60815-2 provides several benefits, including:
IEC 60815-2 is the international standard that gives procedures for selecting and testing insulators used on overhead power lines, focusing on how to evaluate pollution performance and determine the necessary electrical stress (power-frequency withstand, switching impulse, etc.) for long-term service in polluted environments. Part 2 specifically covers laboratory and site test methods and guidance for assessing pollution severity and how to apply those results to insulator selection.

Creepage distance alone does not guarantee performance. The geometry of the insulator sheds matters. IEC 60815-2 outlines strict profile parameters, including:
IEC 60815 is a multi-part standard. The basis for the structure, definitions, and general methodology is fully laid out in ( Definitions, information and general principles ). Therefore, Part 1 and Part 2 are meant to be used together. Part 2 then builds on this foundation with the specific guidelines and tools needed for its target insulator class. The use of IEC 60815-2 provides several benefits,
A key first step is to evaluate the at the proposed installation site. This involves assessing the expected level of pollution from sources like coastal salt, industrial emissions, desert dust, or agricultural sprays. The SPS is categorized into defined pollution classes (e.g., light, medium, heavy, very heavy).

This standard replaces the older IEC 60815 (1986) and moves away from simple look-up tables toward a more rigorous, site-specific design approach. It establishes how to determine the required to prevent insulator flashover based on environmental pollution levels. Key Content & Technical Focus
