ISO/DIS 10437
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 10437 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures
for petroleum and natural gas industries, Subcommittee SC 6, Processing equipment and systems.
This third edition cancels and replaces the second edition (ISO 10437:2003), which has been technically
revised.

Introduction
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.
This International Standard requires the purchaser to specify certain details and features.
A bullet (z) 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 the data
sheets; otherwise it should be stated in the quotation request (enquiry) or in the order.
In this International Standard, where practical, US Customary units have been included in brackets for
information.

DRAFT INTERNATIONAL STANDARD ISO/DIS 10437
Petroleum, petrochemical and natural gas industries — Steam
turbines — Special-purpose applications
1 Scope
This International Standard specifies the minimum requirements for steam turbines for special purpose applications for
use in the petroleum, petrochemical and natural gas industries. These requirements include basic design, materials,
fabrication, inspection testing and preparation for shipment. It also covers the related lube-oil systems, instrumentation,
control systems and auxiliary equipment. It is not applicable to general-purpose steam turbines, which are covered in
API Std 611.
