Aerospace fluid systems — Elastomer seals — Storage and shelf life
ISO 27996:2009 is applicable to the general requirements for data recording procedures, packaging, and storing of elastomeric seals and seal assemblies which include an elastomeric element prior to the seal being assembled into hardware components. The requirements for packaging are an integral part of the controlled storage procedure and provide a means of positive product identity from the time of manufacture to the time of assembly into a component. ISO 27996:2009 does not establish limitations or storage times for assembled components nor the operating life of these components. The information contained in ISO 27996:2009 is intended for use by those organizations that do not have specific requirements or recommendations already in place for the control of elastomeric seals and seal assemblies. ISO 27996:2009 can be specified in control, storage and procurement documents. However, when the requirements of ISO 27996:2009 are in conflict with the customer's requirements or specifications, the requirements of the customer's detailed specifications take precedence.

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 27996 was prepared by Technical Committee ISO/TC 20, Aircraft and Space Vehicles, Subcommittee
SC 10, Aerospace fluid systems and components.

Introduction
In fluid power systems, power is transmitted and controlled through a fluid (liquid or gas) under pressure within
an enclosed circuit. Components are designed to meet these requirements under varying conditions. Testing
of components to meet performance requirements provides users a basis of assurance for determining design
application and for checking component compliance with their stated requirements.

The requirements for packaging are an integral part of the controlled storage procedure and provide a means
of positive product identity from the time of manufacture to the time of assembly into a component.
This International Standard does not establish limitations or storage times for assembled components nor the
operating life of these components.
The information contained in this International Standard is intended for use by those organizations that do not
have specific requirements or recommendations already in place for the control of elastomeric seals and seal
assemblies.
