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 10438-4 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures
for the petroleum, petrochemical and natural gas industries, Subcommittee SC 6, Processing equipment and
systems.
ISO 10438 consists of the following parts, under the general title Petroleum, petrochemical and natural gas
industries — Lubrication, shaft-sealing and control-oil systems and auxiliaries:
Part 1: General requirements
Part 2: Special-purpose oil systems
Part 3: General-purpose oil systems
Part 4: Self-acting gas seal support systems

Introduction
ISO 10438 is based on API Std 614, 4th edn., April 1999, divided into four parts as follows:
Part 1: General requirements is based on Chapter 1 of API Std 614;
Part 2: Special-purpose oil systems is based on Chapter 2 of API Std 614;
Part 3: General-purpose oil systems is based on Chapter 3 of API Std 614;
Part 4: Self-acting gas seal support systems (this part) is based on Chapter 4 of API Std 614.
Users of this part of ISO 10438 should be aware that further or differing requirements might be needed for
individual applications. This part of ISO 10438 is not intended to inhibit a vendor from offering, or the
purchaser from accepting, alternative equipment or engineering solutions for the individual application. This
may be particularly appropriate where there is innovative or developing technology. Where an alternative is
offered, the vendor should identify any variations from this part of ISO 10438 and provide details.
This part of ISO 10438 requires the purchaser to specify certain details and features.
A bullet (•) at the beginning of a clause or subclause indicates that either a decision is required or further
information is to be provided by the purchaser. This information or decision should be indicated on suitable
data sheets; otherwise it should be stated in the quotation request (inquiry) or in the order.
INTERNATIONAL STANDARD ISO 10438-4:2003(E)
Petroleum, petrochemical and natural gas industries —
Lubrication, shaft-sealing and control-oil systems and
auxiliaries —
Part 4:
Self-acting gas seal support systems
1 Scope
This part of ISO 10438 specifies requirements for support systems for self-acting gas seals (dry gas seals) as
described in ISO 10439, for use in the petroleum, petrochemical and natural gas industries as well as in other
industries by agreement. It is intended to be used in conjunction with ISO 10438-1. ISO 10438 in its entirety
specifies requirements for lubrication systems, oil-type shaft-sealing systems, self-acting gas seal systems,
control-oil systems and other auxiliaries for general- or special-purpose applications. These systems can
serve equipment such as compressors, gears, pumps and drivers.
None of the parts of ISO 10438 is applicable to internal combustion engines.
NOTE Annex A provides schemas of typical dry-gas seal support systems.
2 Normative references
