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 2563 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 2563:1974), which has been technically revised.

INTERNATIONAL STANDARD ISO 2563:2009(E)

Aircraft ducting and piping — Profile dimensions for flanges of
V-band couplings
1 Scope
This International Standard gives the profile dimensions of V-band couplings, and the associated inch-based
aircraft ducting and piping for the following external flange profiles:
⎯ lightweight solid profile;
⎯ medium-weight solid profile;
⎯ heavyweight solid profile;
⎯ narrow sheet metal profile;
⎯ wide sheet metal profile;
⎯ wide solid profile;
⎯ wide sheet metal to solid profile.
2 Dimensions
2.1 The profile dimensions of a mating pair of flanges of V-band couplings shall comply with Figures 1 to 7,
in accordance with the type of coupling required for the application. The dimensions are given in millimetres,
with inch equivalents in parentheses.
2.2 The design of joints is at the discretion of the user, but the joint design shall remain within the range of
the profiles given in this International Standard.
2.3 Flange halves are illustrated as being identical in the figures, but at the discretion of the user, the flange
faces can be asymmetric, allowing the creation of locating spigots and recesses or other locating features,
within the boundaries of the overall definition. The narrow and wide sheet metal flanges are identical. The
single wide sheet metal profile flange shown in Figure 7 should be mated with a single solid profile flange
shown in Figure 6.
2.4 The single flange end shown in Figure 7 may be machined on a pump or valve, which mates with
ducting.
