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 —

— Part 1: Hose assemblies

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.

1.1
hose assembly
hose, ready for use, equipped with hose fittings at ends
NOTE See Figure 1.
Figure 1 — Hose assembly

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”.

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

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.
