Introduction
This International Standard is based on the 7th edition of the American Petroleum Institute standard API 617.
Further or differing requirements might be needed for individual applications. This International
Standard is not intended to inhibit a supplier 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 supplier should
identify any variations from this part of ISO 10439 and provide details.
An asterisk (*) at the beginning of the paragraph of a clause or subclause indicates that either a decision
is required or further information is to be provided by the purchaser. This information is indicated on
data sheets or stated in the enquiry or purchase order (see examples in Annex A in this part of ISO 10439,
ISO 10439-3:2015, Annex A, and ISO 10439-4:2015, Annex A).
This International Standard includes the following annexes:
— Annex A: Datasheets;
— Annex B: Vendor (Supplier) data and drawing requirements (VDDR);
— Annex C: Centrifugal compressor nomenclature;
— Annex D: Typical materials;
— Annex E: Inspector’s checklist;
— Annex F: Nozzle forces and moments;
— Annex G: Full load, full pressure, full speed testing;
Annex A forms a normative part of this part of ISO 10439. Annex B to Annex G are for information only.
In this International Standard, where practical, US Customary units are included in parentheses for
information.

not permitted in other services unless specifically approved by the purchaser. If approved, the supplier shall
define the physical limits and the maximum allowable working pressure of each section of the casing.
4.6.1.3 Unless otherwise specified, casings shall be radially split when the partial pressure of hydrogen
(at maximum allowable working pressure) exceeds 1 380 kPa gauge (200 psi gauge). The partial pressure
of hydrogen shall be calculated by multiplying the highest specified mole (volume) per cent of hydrogen
by the maximum allowable working pressure.
4.6.1.4 Each axially split casing shall be sufficiently rigid to allow removal and replacement of its upper
half without disturbing rotor-to-casing running clearances and bearing alignment.
4.6.1.5 Axially split casings shall use a metal-to-metal joint (with a suitable joint compound compatible
with the process gas) that is tightly maintained by suitable bolting. Gaskets (including string type) shall

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.
ISO 10439-2 was prepared by Technical Committee ISO/TC 118, Petroleum and natural gas industries,
Subcommittee SC 1, Axial and centrifugal compressors and Expander-compressors in collaboration with
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 10439:2002), which has been technically
revised and split into four (4) parts.
ISO 10439 consists of the following parts, under the general title Axial and centrifugal compressors and
expander-compressors for special purpose applications handling gas of process air for petroleum,
petrochemical and natural gas industries:
Part 1: General requirements
Part 2: Non-integrally geared centrifugal and axial compressors
Part 3: Integrally geared centrifugal compressors
Part 4: Expander-compressors

Introduction
th
This International Standard is based on the 7 edition of the American Petroleum Institute standard API 617.
Users of this International Standard should be aware that further or differing requirements may be needed for
individual applications. This International Standard 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 International Standard and provide details.
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 data sheets or stated
in the enquiry or purchase order (see examples in ISO 10439-2 Annex A, ISO 10439-3 Annex A and
ISO 10439-4 Annex A).
In this International Standard, where practical, US Customary units are included in parentheses for
information.

Part 2:
Non-integrally geared centrifugal and axial compressors
1 Scope
This International standard specifies minimum requirements and gives recommendations for axial
compressors, single-shaft and integrally geared process centrifugal compressors and expander-compressors
for special purpose applications that handle gas or process air in the petroleum, petrochemical and natural
gas industries. This part of ISO 10439 specifies requirements for non-integrally geared centrifugal and axial
compressors, in addition to the general requirements specified in ISO 10439-1. These machines do not have
gears integral with their casing but can have external gears.
NOTE See ISO 10439-3 for integrally geared process compressors, or API Std 672 for packaged plant instrument air
compressors.
