For traditional insulators, the standard focuses heavily on the profile (shape) of the shed. It utilizes the ** To correctly dimension an insulator using the IEC

Early standards provided general creepage distances but failed to account for local pollution severity. IEC 60815 (first published in 1986 and significantly revised starting in 2008) filled this gap by introducing a structured classification of pollution environments and a clear methodology to match insulator characteristics to site conditions.
