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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO’s adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso
.org/iso/foreword .html.
This document was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture
and forestry, Subcommittee SC 18, Irrigation and drainage equipment and systems.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www .iso .org/members .html.
This first edition cancels and replaces ISO/TR 15155:2005, which has been technically revised to
include sprayers (ISO 8026) and water meters (ISO 16399).
A list of all parts in the ISO/TR 15155 series can be found on the ISO website.

TECHNICAL REPORT ISO/TR 15155-1:2018(E)
Agricultural irrigation equipment — Test facilities for
agricultural irrigation equipment —
Part 1:
General
1 Scope
This document gives guidelines for the design, selection, installation and use of the equipment required
to establish basic test facilities for irrigation equipment evaluation. It provides the information
sufficient to complement the detailed procedures included in ISO 7714, ISO 8026, ISO 9261, ISO 9635 (all
parts), ISO 9644, ISO 9911, ISO 10522, ISO 15886 and ISO 16399 for the testing of agricultural irrigation
system components, specifically emitters, sprinklers, valves, sprayers and water meters.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:

3.1
test bench
collection of components, including water supply/receiving reservoir, piping, fittings and
instrumentation, assembled to test an agricultural irrigation component
3.2
test facility
collection of components, including water supply, test bench(es) (3.1) and shelter, used to test agricultural
irrigation valves, sprinklers and emitters
3.3
net positive suction head available
NPSHa
arithmetic difference between the available total suction head at the impeller of a centrifugal pump (3.6)
and the vapour pressure head (3.7)
3.4
net positive suction head required
NPSHr
arithmetic difference between the total suction head at the impeller of a centrifugal pump (3.6) required
for the pump to operate properly and the vapour pressure head (3.7), as specified by the manufacturer
3.5
static pressure head
sum of the head associated with atmospheric pressure and the gauge pressure head measured
approaching the inlet of the impeller of a centrifugal pump
3.6
total suction head at the impeller of a centrifugal pump
sum of the static pressure head (3.5) and the velocity head measured approaching the inlet of the
impeller of a centrifugal pump and corrected to the centreline of the impeller for a centrifugal pump
mounted horizontally or to the datum of the tip of the inlet vanes for a centrifugal pump mounted
vertically
3.7
vapour pressure head
head associated with the absolute pressure at which a liquid vaporizes, as determined by the physical
properties of the liquid and its temperature
