Metallic materials - Tube ring hydraulic pressure test (ISO 15363:2017)

ISO 15363:2017 specifies the ring hydraulic pressure test for metallic tubes. It is generally applied to tubes with an outside diameter greater than 120 mm and outside diameter to thickness ratio of not less than 20.
The objective of this test is to ascertain the value of the hoop stress required to produce a specified total circumferential (hoop) strain.

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

Metallic materials — Tube ring hydraulic pressure test
1 Scope
This document specifies the ring hydraulic pressure test for metallic tubes. It is generally applied to
tubes with an outside diameter greater than 120 mm and outside diameter to thickness ratio of not less
than 20.
The objective of this test is to ascertain the value of the hoop stress required to produce a specified
total circumferential (hoop) strain.
2 Symbols
Symbols and corresponding designations are given in Table 1.

NOTE For symbols used in standards for steel tubes, please see Annex B.
3 Principle
Unrestrained expansion of the test ring between two platens, under internal hydraulic pressure; the
outer circumference of the tube is the effective test piece gauge length.
The test is carried out on a test piece taken from a welded or seamless tube of thickness up to a limit
dependent upon the capacity of the machine and the strength of the tube (see Figure 1). All sharp edges
are removed from product machined surfaces before testing. Where the hydraulic pressure required to
produce the specified circumferential strain exceeds the capacity of the test machine, modified tests
may be carried out as described in Annex A.
The test is specified when a measure of the hoop
