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 Technical Committee ISO/TC 131, Fluid power systems, Subcommittee
SC 4, Connectors and similar products and components, in collaboration with the European Committee
for Standardization (CEN) Technical Committee CEN/TC 459, ECISS - European Committee for Iron and
Steel Standardization, in accordance with the Agreement on technical cooperation between ISO and
CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 1179-2:2013), which has been technically
revised.
The main changes are as follows:
— Clause 4, Interchangeability warning, concerning the hazards of intermixing of stud ends with
various port types, has been added;
— material requirements for elastomeric seal have been added;
— test methods, test report and re-use of components have been replaced with the equivalent
requirements of ISO 19879;
— Figures 1 and 2 have been redrawn;
— the tables have been renumbered to the order in which they are cited in the text (Table 2 to Table 1,
Table 4 to Table 2, Table 3 remains the same, Table 5 to Table 4, Table 1 to Table 5);
— Annex A and the references to the annex have been deleted;
