IEEE 3336-2025

The guide applies to aircraft warning marker balls used on overhead transmission lines, especially on the long span transmission lines that cross over a river or sea or on the transmission lines above 500 kV. The guide provides technical guidance, test setup, test methods, test parameters, and acceptance criteria of vibration tests for aircraft warning marker balls on overhead transmission lines.

The purpose of this guide is to define technical guidance, test methods and criteria for vibration tests for aircraft warning marker balls used on transmission lines. The guide enables improvement in the industry of marker ball anti-vibration performance, helps reduce accidents and improve the operational safety of transmission lines.
