Ships and marine technology — Identification colours for the content of piping systems — Part 2: Additional colours for different media and/or functions
ISO 14726-2 specifies additional colours to be used with the main colours given in ISO 14726-1 for marking of piping systems in accordance with the content and/or function on board ships and marine structures. Additional colours may not be used if no differentiation of a single main colour on board is needed. ISO 14726-2 does not apply to piping systems for medical gases, industrial gases and cargos. It gives no definitions for the listed media and/or functions. These additional colours may also be used, together with the main colours, for piping systems on drawings and diagrams.

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 3.
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 part of ISO 14726 may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 14726-2 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 3,
Piping and machinery.
It cancels and replaces ISO 5571:1981, of which it constitutes a technical revision.
ISO 14726 consists of the following parts, under the general title Ships and marine technology — Identification
colours for the content of piping systems:
Part 1: Main colours and media
Part 2: Additional colours for different media and/or functions
Annexes A and B of this part of ISO 14726 are for information only.

Part 2:
Additional colours for different media and/or functions
1 Scope
This part of ISO 14726 specifies additional colours to be used with the main colours given in ISO 14726-1 for the
marking of piping systems in accordance with the content and/or function on board ships and marine structures.
Additional colours may not be used if no differentiation of a single main colour on board is needed.
This part of ISO 14726 does not apply to piping systems for medical gases, industrial gases and cargos.
It gives no definitions for the listed media and/or functions.
These additional colours may also be used, together with the main colours, for piping systems on drawings and
diagrams.
