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 the European Committee for Standardization (CEN) TechnicalCommittee
CEN/TC 342, Metal hoses, hose assemblies, bellows and expansion joints, in collaboration with ISO
Technical Committee ISO/TC 5, Ferrous metal pipes and metallic fittings, Subcommittee SC 11, Metal
hoses and expansion joints, in accordance with the Agreement on technical cooperation between ISO and
CEN (Vienna Agreement).
This fourth edition cancels and replaces the third edition (ISO 7369:2004), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— shift updated normative references into Bibliography;
— introduction of new definitions related to "design pressure", "metal braid strand", "braided braid"
and " nominal size of metal hose assembly";
— revision of definitions related to "maximum allowable pressure", "maximum allowable temperature"
and "minimum allowable temperature";
— update of Annex A to include French, German and Dutch terms and deletion of Annexes B, C, D and E.
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.

ISO 7369:2020(E)
Introduction
It was decided to produce a standard under the Vienna Agreement on technical cooperation between
ISO and the European Committee for Standardization CEN in order to maintain one document. The
opportunity was taken to re-format and add additional information, which was not available when the
standard was originally produced.
INTERNATIONAL STANDARD ISO 7369:2020(E)
Pipework — Metal hoses and hose assemblies —
Vocabulary
1 Scope
This document defines current terms concerning metal hoses, metal hose assemblies and component
parts.
This document applies to:
a) stripwound metal hoses and hose assemblies;
b) corrugated metal hoses and hose assemblies.
NOTE 1 These hoses can be used braided, covered or lined.
NOTE 2 Equivalent terms in English, French, German and Dutch are given in Annex A.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at http:// www .electropedia .org/
3.1 General
3.1.1
metal hose
metal duct, generally of circular or polygonal section, able to withstand repeated bending without damage
3.1.1.1
stripwound metal hose
hose manufactured from a helically wound pre-formed strip, generally with a right-hand lead, where
the turns, with or without packing (3.2.1.2), are connected together by single or double overlapping and
flexibility (3.1.11) is obtained by sliding adjacent turns over each other
3.1.1.2
corrugated metal hose
pressure-tight hose made from tube or from strip (3.2.1.1) with corrugations, helicoidal or annular to
the axis of the hose, made by deforming the metal, and where flexibility (3.1.11) and pliability (3.1.12)
are obtained by bending of the corrugations
3.1.2
metal hose assembly
assembly of a metal hose (3.1.1) with its end fittings (3.2.2.4)
ISO 7369:2020(E)
3.1.3
nominal pressure
PN
numerical designation which is a convenient rounded number for reference purposes
Note 1 to entry: This defined number is a dimensionless number indirectly related to a pressure value in bar
(1 bar = 0,1 MPa).
Note 2 to entry: The definition is adapted from ISO 7268. See also EN 1333.
3.1.4
maximum operating pressure
maximum pressure that may be reached in an installation
Note 1 to entry: Care should be taken to ensure that both the temperature and the pressure are quoted together.
3.1.5
design pressure
maximum pressure at the design temperature for which the hose assembly needs to be designed, as
specified by the customer
Note 1 to entry: The design pressure in an installation should be equal to or higher than the maximum operating
pressure (3.1.4).
3.1.6
maximum allowable pressure
maximum pressure at the design temperature for which the hose assembly is designed, as specified by
the manufacturer
Note 1 to entry: The maximum allowable pressure should be equal to or higher than the design pressure (3.1.5).
Note 2
