Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies

(ISO member bodies). The work of preparing International Standards is normally carried out through ISO

technical committees. Each member body interested in a subject for which a technical committee has been

established has the right to be represented on that committee. International organizations, governmental and

non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the

International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International Standards

adopted by the technical committees are circulated to the member bodies for voting. Publication as an

International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 15749-5 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee

SC 3, Piping and machinery.

ISO 15749 consists of the following parts, under the general title Ships and marine technology — Drainage

systems on ships and marine structures:
— Part 1: Sanitary drainage-system design
— Part 2: Sanitary drainage, drain piping for gravity systems
— Part 3: Sanitary drainage, drain piping for vacuum systems
— Part 4: Sanitary drainage, sewage disposal pipes
— Part 5: Drainage of decks, cargo spaces and swimming pools

Part 5:
Drainage of decks, cargo spaces and swimming pools
1 Scope

This part of ISO 15749 applies to the planning and design of drain lines for gravity-operated conveyance of

grey water from
 weather decks and non-weathertight spaces on ships and marine structures,
 ro-ro spaces,
 cargo spaces, and
 swimming pools.

NOTE Wastewater from spaces in which live animals are accommodated is classified as sewage water and shall be

discharged in accordance with MARPOL regulations. For drainage of sewage, see ISO 15749-2 and ISO 15749-3.

For planning and basic requirements, see ISO 15749-1.
