この概要は現在英語のみで提供しています。

適用範囲

This standard is mandatory for the drafting, broadcasting, and usage of Chinese and English navigational warnings along the coastal waters of the People's Republic of China. It applies to maritime safety administrations, coast radio stations, and vessels operating in these waters. It does not apply to inland river navigational warnings unless specifically referenced. The standard references GB 4696 for navigation aids.

技術要求

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. It details the specific formatting rules for geographical coordinates, time expressions (using Beijing Time for Chinese and UTC for English), and the identification codes for various regional Maritime Safety Administrations (MSA). 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.

試験方法

While this standard does not involve traditional laboratory testing, it establishes specific evaluation procedures for message formatting and broadcasting. Key procedural checks include verifying the accuracy of geographical coordinates, the correct usage of time formats, and the appropriate application of standardized vocabulary for different hazard categories. Compliance is assessed through the review of the drafted warning messages before dissemination by the coast radio stations.
