ISO 10440-1:2007(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 10440-1 was prepared by Technical Committee ISO/TC 118, Compressors and pneumatic tools,
machines and equipment, Subcommittee SC 1, Process compressors.
This second edition cancels and replaces the first edition (ISO 10440-1:2000), which has been technically
revised.
ISO 10440 consists of the following parts, under the general title Petroleum, petrochemical and natural gas
industries — Rotary-type positive-displacement compressors:
⎯ Part 1: Process compressors
⎯ Part 2: Packaged air compressors (oil-free)

ISO 10440-1:2007(E)
Introduction
This part of ISO 10440 is based on API 619, 4th edition, December 2004, with the intent that the 5th edition of
API 619 will be identical to this part of ISO 10440.
Users of this part of ISO 10440 should be aware that further or differing requirements may be needed for
individual applications. This part of ISO 10440 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 10440 and provide details.
A bullet (•) at the beginning of a subclause or paragraph 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 part of ISO 10440, where practical, US Customary (USC) units are included in brackets for information.
Dedicated datasheets for SI units and for USC units are provided in Annex A.

ISO 10440-1:2007(E)
3.8
dry screw compressor
helical-lobe rotary compressor that uses no liquid for sealing the rotor clearances and driving the non-coupled
rotor
NOTE 1 The rotor-to-rotor relationship is maintained by timing gears on each rotor and the non-coupled rotor is driven
by the coupled rotor through the timing gears.
NOTE 2 No rotor-to-rotor contact occurs in the dry screw compressor.
3.9
fail-safe
system that causes the equipment to revert to a permanently safe condition (shutdown and/or depressurized)
in the event of a component failure or failure of the energy supply to the system
3.10
flooded screw compressor
helical-lobe rotary compressor with a lubricant (compatible with the process gas) injected into the rotor area
after the closed thread position of the rotor
NOTE This lubricant helps seal rotor clearances and establishes an oil film between the rotors. One rotor drives the
other in the absence of a timing gear.
3.11
gas/oil separator
pressure-containing device, usually a vessel, used to separate entrained oil from the process gas
3.12
gauge board
bracket or plate used to support and display gauges, switches and other instruments
NOTE 1 A gauge board is open and not enclosed
NOTE 2 A gauge board is not a panel. A panel is an enclosure. Refer to 3.31 for the definition of a panel.
3.13
general-purpose application
application that is usually spared or is in non-critical service
3.14
hold-down bolts
mounting bolts
bolts holding the equipment to the mounting plate
3.15
hydrodynamic bearings
bearings that use the principles of hydrodynamic lubrication, where bearing surfaces are oriented such that
relative motion forms an oil wedge or wedges to support the load without shaft-to-bearing contact
3.16
inlet volume flow
flow rate expressed in volume flow units at the conditions of pressure, temperature, compressibility and gas
composition, including moisture content, at the compressor
...
