It provides a uniform method that is recognized internationally, simplifying communication between design engineers, manufacturers, and utility operators.
Inland areas with little to no industrial activity.
The IEC 60815-2 PDF contains the following key sections:
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. iec 60815-2 pdf
The standard is officially titled "Selection and dimensioning of high-voltage insulators intended for use in polluted conditions - Part 2: Ceramic and glass insulators for a.c. systems." This document is a Technical Specification (TS) , meaning it provides a consensus-based, informative guidance that is still under development but is essential for immediate use. It is published by the International Electrotechnical Commission (IEC), the world's leading organization for international electrical and electronic standards.
. The standard's latest 2025 revision had simplified the profile suitability checks, confirming that for these exact coastal conditions, alternating sheds with a high creepage-to-clearance ratio were the only way to prevent a total blackout.
: It includes specific factors for altitude, insulator diameter ( Kdcap K sub d ), and installation position (horizontal vs. vertical). Recommended Structure for Your Content It provides a uniform method that is recognized
Many engineering firms and utilities maintain corporate subscriptions to databases like IEEE Xplore, IHS Markit, or Techstreet, providing employees with direct access to standard PDFs. Conclusion
focuses exclusively on ceramic and glass insulators operating in alternating current (AC) systems . It replaces the older, single-document IEC 60815 standard (originally published in 1986) by introducing a more rigorous, site-specific approach to insulator design. Core Methodology of the Standard
To better assist with your specific engineering requirements, please let me know: Are you looking to design for an or a DC system ? The basis for the structure, definitions, and general
This is the fundamental design metric provided by the standard. It defines the minimum leakage path (creepage distance) required per kilovolt of system voltage (
Calculate initial creepage values based on the Site Pollution Severity (SPS) class of the installation area.
: Organizations like ANSI (US), BSI (UK), or DIN (Germany) often sell localized versions of the IEC text.
IEC 60815 is split into several parts to address different materials: : General principles and definitions. Part 2 : Glass and porcelain insulators (this document). Part 3 : Polymer (composite) insulators. How to Access the PDF
