ISO 16589-5:2011

Rotary shaft lip-type seals incorporating thermoplastic sealing elements — Part 5: Identification of visual imperfections

ISO 16589 specifies seals utilizing sealing elements manufactured from suitably formulated compounds based on thermoplastic materials, such as polytetrafluoroethylene (PTFE). They are considered suitable for use under low-pressure conditions. ISO 16589-5:2011 defines and classifies typical surface imperfections that could impair the function of the seals, and is intended as a convenience for purchasers and manufacturers in their discussions concerning the importance of these imperfections in different applications.

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 16589-5 was prepared by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 7,
Sealing devices.
This second edition cancels and replaces the first edition (ISO 16589-5:2001), which has been technically
revised.
ISO 16589 consists of the following parts, under the general title Rotary shaft lip-type seals incorporating
thermoplastic sealing elements:
⎯ Part 1: Nominal dimensions and tolerances
⎯ Part 2: Vocabulary
⎯ Part 3: Storage, handling and installation
⎯ Part 4: Performance test procedures
⎯ Part 5: Identification of visual imperfections

ISO 16589-5:2011(E)
Introduction
Rotary shaft lip-type seals are used to retain fluid in equipment where the differential pressure is relatively low.
Typically, the shaft rotates and the housing is stationary, although in some applications the shaft is stationary
and the housing rotates.
Dynamic sealing is normally the result of a designed interference fit between the shaft and a flexible element
incorporated in the seal.
Similarly, a designed interference fit between the outside diameter of the seal and the diameter of the housing
bore retains the seal and prevents static leakage.
Careful storage and handling and proper installation of all seals are necessary to avoid hazards, both prior to
and during installation, which would adversely affect service life.
