This standard specifies the structural composition and formatting requirements for navigational warning documents. It defines the essential elements including the title, serial number, warning grade (ROUTINE, IMPORTANT, VITAL), broadcasting station, and delivery time. Strict adherence to the document template is required for all maritime safety administrations. The standard outlines the fundamental structure of the warning message text, which consists of a number, area, basic content, and issuing unit.

Furthermore, the standard categorizes warning messages into seven main types: aids to navigation, navigational hazards, overwater and underwater activities, military exercises, distress and rescue operations, designated areas, and maritime security. It provides standardized vocabulary and sentence structures for each category to ensure clarity and consistency in communication.
