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 10380 was prepared by the European Committee for Standardization (CEN) Technical Committee

Introduction
It was decided to produce an International Standard under the Vienna Agreement on technical cooperation between
ISO and the European Committee for Standardization (CEN) in order to maintain a unique EN ISO document.
The major changes in this revision of this International Standard are the following:
— update of the structure of the International Standard;
— update of the test and performance requirements to reflect the practice of the industry at the time of publication;
— introduction of an evaluation of conformity and a system of certification.
This International Standard is a base standard for corrugated metal hoses and hose assemblies for general purpose.
Corrugated metal hoses and metal hose assemblies conforming to all aspects of this International Standard
are considered to be designed and manufactured to sound engineering practice.
The requirements of this International Standard are of importance to designers, manufacturers, users, suppliers
and importers of corrugated metal hoses.
Non-permanent, detachable connections between hoses and fittings are available in the market. Their design
is not covered by this International Standard.

SIST EN ISO 10380:2013
ISO 10380:2012(E)
These design requirements shall ensure that the construction of corrugated metal hoses, where properly
installed and used correctly, under chemical, mechanical and thermal conditions for general use, provide long-
term safe operation without degradation.
Corrugated metal hoses are divided into the following four different types (see Table 7) and tested accordingly,
as described in Clause 5:
— type 1-50: corrugated metal hoses of high flexibility with high fatigue life;
— type 1-10: corrugated metal hoses of high flexibility with medium fatigue life;
— type 2-10: corrugated metal hoses of average flexibility;
— type 3: corrugated metal hoses where only pliability is required.
Corresponding radii for pliability tests are given in Table 6 and corresponding radii for fatigue tests are
given in Table 8.
NOTE 1 The fatigue life of a corrugated metal hose is mainly affected by bend radius, pressure and temperature:
— at a given bend radius, fatigue life increases by lowering the working pressure;
— at a given working pressure, fatigue life increases by increasing the bend radius.
NOTE 2 Passing a test does not imply that the minimum or average fatigue life can be reached in circumstances other
than those specified in the test procedure.
NOTE 3 Where a user requires a higher fatigue life than given in this International Standard, the manufacturer can
be consulted.
NOTE 4 The installation configuration, such as type of movement, pressure characteristics and environmental
condition, have a strong influence on the fatigue life of a corrugated metal hose assembly.
NOTE 5 The lubrication condition of the braid influences the fatigue life of a corrugated metal hose. A reduction of
lubrication can occur during assembly, cleaning, transportation, storage or in service conditions.
4.2 Nominal sizes, DN
The designation of standard nominal sizes shall be as given in Table 1. The internal diameter of a corrugated
metal hose shall not be less than 98 % of its nominal size designation.

Other nominal sizes can be produced in accordance with the customer’s requirements. Their performance (see
Clause 5) should be interpolated from the values for the nearest nominal sizes, as given in Table 1.
4.3 Overall length, l
O
If not explicitly otherwise specified between the manufacturer and purchaser, the overall length, l , of a metal
O
hose assembly shall be the length as ordered to a tolerance of +3 % and –1 %.
For short hose assemblies, these tolerances do not apply because often a tolerance of one corrugation is
necessary, depending on the attachment technology of fittings. On no account shall the overall length be less
than 99 % of the length as ordered.
NOTE For minimum overall length of a braided hose assembly, see 4.6.
4.4 Hose design
The corrugated metal hose shall be made from seamless tube, welded tube or strip. Where welded construction
is used, the hose may be butt- or lap-welded, the weld being axial or spiral along the length of the hose and in
accordance with qualified welding and forming procedures. Corrugations may be annular or helical.
The corrugation shall be of regular form, continuous and concentric along the length of the hose, and shall
be free of defects, such as scores, dents, cuts or weld variations, which can cause premature failure. Where
required, a hose can be heat treated after forming.
NOTE Heat treatment influences flexibility, fatigue life and pressure-bearing capacity. It is, therefore, necessary for
the manufacturer to provide details on the characteristics affected by this type of treatment.
4.5 Materials
Materials for the manufacture of corrugated metal hoses and metal hose assemblies shall be selected on the
basis of their suitability for fabrication (cold forming, welding, etc.) and for the conditions under which they shall
be used. A list of suitable materials is given in Table 2.
Alternative equivalent European material designations are given in Table A.3.
