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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent rights
in respect thereof. As of the date of publication of this document, ISO had not received notice of (a) patent(s)
which may be required to implement this document. However, implementers are cautioned that this may not
represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

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 20, Aircraft and space vehicles, Subcommittee
SC 10, Aerospace fluid systems and components.
This second edition cancels and replaces the first edition (ISO 10583:1993), which has been technically
revised.
The main changes are as follows:
— — clause 2,deletion of ISO 6771 from Clause 2has been removed as a normative reference ;
— revision of subclause 5.10;
— revision of Table 1— subclause 5.10, Fire test, was updated;
— — Table 1, Test specimens, free tube length between sleeves, was updated;
— — ;
— addition of Bibliography was added;.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
ThisThe intention of this document has been preparedis to standardize the test methods for the qualification
of fittingfittings on tube assemblies used in aircraft fluid systems. The tests are intended to simulate the most
strenuous demands encountered in aircraft. These test methods are relevant for fittingfittings on tube
assemblies which are used in systems where a malfunction would affect the safety of flight.

Aerospace fluid systems — Test methods for fitting on tube
assemblies
1 Scope
This document specifies test methods for fitting assemblies used in aircraft fluid systems in the pressure and
temperature ranges covered by pressure from classes B, to K, and temperature types I, II and III of ISO 6771.
ItThis document applies each time that it is referred to in a procurement specification or other definition
document which containcontains the pass/ and fail criteria for these tests.
