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 8153-1 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee
SC 10, Aerospace fluid systems and components.
ISO 8153 consists of the following parts, under the general title Aerospace fluid systems and components —
Vocabulary:
— Part 1: Hose assemblies

INTERNATIONAL STANDARD ISO 8153-1:2009(E)

Aerospace fluid systems and components — Vocabulary —
Part 1:
Hose assemblies

Scope
This part of ISO 8153 defines terms used for all types of hose assemblies.
General terms can be made more precise through the addition of supplementary terminology relating to the
design, range of application and/or the material of the hose/hose assembly.
Terms and definitions specific to metallic hose assemblies are given in ISO 7369.
NOTE Certain concepts used in this part of ISO 8153 are not applicable to all types of hose assemblies, but only to
specific types, e.g. the term “insert” does not apply to a flexible metal hose without an insert as defined by this part of
ISO 8153.
1 General terms
1.1
hose assembly
hose, ready for use, equipped with hose fittings at ends
NOTE See Figure 1.

Figure 1 — Hose assembly
1.2
hose line
series of several hose assemblies connected to each other
NOTE See Figure 2.

1.3
hose
flexible tubular product consisting of an inner tube and generally equipped with a reinforcement, wrap(s)
and/or braid(s)
NOTE 1 In US English, the common term for a hose consisting of one layer only is “tubing”.
NOTE 2 See Figure 3.

PTFE hose
hose with inner tube made of polytetrafluoroethylene (PTFE)
2.3
plastic hose
hose with inner tube made of plastic material other than PTFE
2.4

3.2
spiral hose
hose with reinforcement consisting of one or more wraps, each alternate wrap being wound in the opposite
direction
3.3
braided and spiral hose
hose with reinforcement consisting of one or more wraps and braids
3.4
convoluted flexible PTFE hose
hose with corrugated inner liner fabricated from PTFE tube, or PTFE tape, helically formed to the axis of the
hose
NOTE 1 Flexibility is obtained by bending the corrugations.
NOTE 2 See ISO 7313.
4 Terms related to hose application
4.1
sleeve hose
hose for sleeve attachment
socketless hose of specific length which can be slipped over rigid tube ends
4.2
preformed hose
hose of which part is permanently set to meet installation requirements
4.3
suction hose
hose that is usable under positive and relative negative pressure
5 Terms related to hose construction
5.1
hose wall
composition of the hose between its inner and outer diameter
NOTE See Figure 3.
5.2
layer
part of the hose wall with a uniform structure
5.2.1
inner tube
layer core
inner part of the hose which performs the function of containing fluid
NOTE See Figure 3.
5.2.2
intermediate layer
layer incorporated between the inner tube and the outermost layer of the hose, made of various reinforcement
elements
NOTE See Figure 3.

5.2.3
hose cover
outer layer
outermost layer of the hose if it is not covered by reinforcement
NOTE See Figure 3.
5.2.4
outer protective cover
layer forming the outer part of the hose wall
EXAMPLE Outer braids or spirals.
NOTE See protective sleeve (9.1).
5.2.5
reinforcement
one or more braids or wraps or helices rendering the hose sufficiently resistant to withstand pressure and/or
vacuum
5.2.6
braid
reinforcement texture made from cross-linked yarn or wire
NOTE See Figure 3.
5.2.7
helix
helical wire placed in the hose wall to ensure form stability of the hose in the event of a vacuum or external
loads
5.2.8
wrap
reinforcement made up of an assembly of yarns or wires helically wrapped to ensure resistance to pressure
6 Terms related to hose assembly
6.1
hose fitting
component, or subassembly of a hose assembly, whose purpose is to connect hoses to an appropriate fluid
circuit
NOTE 1 The terms defined in Clause 6 apply to flexible metal hose assemblies only under certain conditions, in view of
the fact that these are generally supplied completely mounted.
NOTE 2 A clear designation includes the following (in the order given):
— hose side configuration;
— connecting end configuration.
The end fitting can be equipped with a bend or an elbow. Some end fittings can be equipped with a swivel nut, which can
be designed with or without a thrust wire.
6.2 Configuration of hose side of fitting
NOTE See Figure 4.
