series (Technical Specification) to address modern materials and higher voltage systems. iTeh Standards Detailed Guide to IEC 60815 (Selection & Dimensioning) 1. Structure of the IEC/TS 60815 Series The standard is divided into several parts: iTeh Standards Part 1: Definitions, information and general principles (IEC/TS 60815-1) Part 2: Ceramic and glass insulators for a.c. systems (IEC/TS 60815-2) Part 3: Polymer insulators for a.c. systems (IEC/TS 60815-3) Part 4: Insulators for d.c. systems (IEC/TS 60815-4) 2. Key Definitions and Principles Site Pollution Severity (SPS): The severity of the environment (light to very heavy). Unified Specific Creepage Distance (USCD):

Published originally in 1986 (and reaffirmed in various editions until its withdrawal), IEC 815 was the cornerstone document that taught the world how to map environmental pollution—from desert dust to coastal salt—onto a specific leakage distance for ceramic and glass insulators.

Choose a profile (profile type, shed type) that fits the required, corrected creepage distance. iTeh Standards 4. Pollution Severity Levels (SPS Class) iTeh Standards The IEC 60815 defines five classes of pollution severity: Class a (Very Light): Remote from coast/industry. Class b (Light): Low density pollution. Class c (Medium): Coastal areas, moderate industrial. Class d (Heavy): High density coastal/industrial. Class e (Very Heavy): Very close to severe sea/industrial sources. 5. Correction Factors (RUSCD) iTeh Standards

The original 1986 document was a relatively simple Technical Report (TR). It categorized pollution into four levels (Light, Medium, Heavy, and Very Heavy) and recommended a minimum nominal specific creepage distance for each. Under-ribs: If you are searching for the ,

The IEC eventually restructured this standard into the series. While "IEC 815" is still widely referenced in older contracts and legacy grid specifications, the current, active technical content is found in IEC 61284 .
