Compliance overview
Scope and applicability
This standard applies to the naming and renaming of undersea geographical features. It is specifically designed for entities within China's maritime jurisdiction and international waters where Chinese naming conventions are applied. It is mandatory for all organizations involved in marine mapping and geographical naming. The standard does not apply to terrestrial or surface water features.
Technical requirements
GB 29432-2012 establishes the mandatory principles for undersea feature nomenclature, dictating that names must consist of a *special term* (专名) followed by a *generic term* (通名). Names should reflect Chinese cultural connotations and must avoid derogatory, vulgar, or identical/homophonic words. The standard specifies strict naming conventions based on a four-tier classification system of undersea features. For instance, Level 1 features (like continental shelves) must be named after their sea area or adjacent islands, while Level 3 and 4 features should use descriptive or culturally commemorative terms. Furthermore, the standard prohibits the use of modern personal names, foreign names, or commercial trademarks.
Testing methods
While traditional physical testing is not applicable, this standard provides an evaluation procedure for nomenclature compliance. It involves verifying the correct selection of *generic terms* against the classification table in Appendix A. Engineers must ensure that the chosen generic term accurately reflects the geographical category and morphological characteristics of the undersea feature. The standard also outlines a review process to prevent overlapping or duplicate generic terms.
