1 Scope

This section GB/T 27888, together with ISO 15749-2 ~ 15749-5 applies to ships and offshore structures in residential areas and grain storage Wastewater discharge system areas (health water discharge system) planning and design.

Storm drainage decks, holds and swimming pools see ISO 15749-5.

GB/T 27888 (all parts) gives the basic rules and minimum requirements for health requirements and maritime environmental protection.

This section does not apply to produce combustible gas/oxygen mixture of oil and chemical pollution of water pipeline system.
