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 15081 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and
forestry, Subcommittee SC 18, Irrigation and drainage equipment and systems.

INTERNATIONAL STANDARD ISO 15081:2005(E)

Agricultural irrigation equipment — Graphical symbols
for pressurized irrigation systems
1 Scope
This International Standard establishes conventional basic graphical symbols for use on drawings and
diagrams concerning the installation of pressurized agricultural irrigation systems.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 81714-1, Design of graphical symbols for use in the technical documentation of products — Part 1: Basic
rules
3 General rules
A group of devices/components is represented by a general symbol. This general symbol shall be completed
for any special component of the group.
In this International Standard, various assemblies of actuators with valves are shown only on the valve
general symbol (see 6.1.1), but they may operate various types of valves.
For a more detailed representation, these basic symbols may be combined with designations specified in a
description, or else a system of more detailed symbols based on these basic symbols may be devised.
The graphical symbols in this International Standard have been designed according to the rules given in
ISO 81714-1. When new symbols are designed, e.g. a combination of symbols as in the present document,
ISO 81714-1 shall be followed.
This International Standard contains graphical symbols primarily for irrigation equipment. Additional graphical
symbols for diagrams can be found
