ISO 10438-1:2007(E)
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 10438-1 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures
for petroleum, petrochemical and natural gas industries, Subcommittee SC 6, Processing equipment and
systems.
This second edition cancels and replaces the first edition (ISO 10438-1:2003), which has been technically
revised.
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

ISO 10438-1:2007(E)
Introduction
This part of ISO 10438 was developed jointly with API 614, 5th edition, together with the other three parts of
ISO 10438.
NOTE API 614 is equivalent to ISO 10438 (all parts).
Users of this part of ISO 10438 should be aware that further or differing requirements can 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
can 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 should be indicated on the datasheet(s);
otherwise it should be stated in the quotation request or in the order.
In this International Standard, United States customary (USC) units are included in brackets for information.

General requirements
1 Scope
This part of ISO 10438 specifies general requirements for lubrication systems, oil-type shaft-sealing systems,
dry-gas face-type shaft-sealing systems and control-oil systems for general- or special-purpose applications.

3.1.32
pressure-limiting valve
PLV
automatic pressure-limiting device, which opens in proportion to the increase in pressure over the opening set
pressure and automatically closes when the upstream pressure is reduced below the set pressure, and which
is actuated by the static pressure upstream of the valve
NOTE 1 These devices are not necessarily tight shutoff when closed, i.e. they may have a small leakage flow when
closed. These devices are designed for liquid service only and are normally used for limiting the discharge pressure of
positive-displacement-type oil pumps and the downstream pressure of fail-open oil-pressure regulating valves when
necessary.
NOTE 2 PLVs require a flowing test system in order to test. Normally, these valves are, therefore, tested in the system
on which they are installed.

pressure safety valve
relief valve
PSV
automatic pressure-relieving device, which opens in proportion to the increase in pressure over the opening
set pressure, has a rapid full opening or pop action characteristic and is actuated by the static pressure
upstream of the valve

devices are considered to be tight shutoff when closed and are normally used in gas, vapour or liquid service.
3.1.34
purchaser
agency that issues the order and specification to the vendor
NOTE The purchaser can be the owner of the plant in which the equipment is installed or the owner's appointed
agent.
