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 3.

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 International Standard may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 10439 was prepared by a Joint Working Group of Technical Committees ISO/TC 118, Compressors,

pneumatic tools and pneumatic machines, and ISO/TC 67, Materials, equipment and offshore structures for

petroleum, petrochemical and natural gas industries, Subcommittee SC 6, Processing equipment and systems.

Annexes C, D and G form a normative part of this International Standard. Annexes A, B, E, F, H, I and J are for

information only.

In this corrected version of ISO 10439 an oversight which saw the words “Final Draft” and its abbreviation left in the

Introduction

This International Standard is based on the sixth 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 applicable 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.

4 Basic design
4.1 General

4.1.1 A bullet (•) at the beginning of a clause indicates that the purchaser is required to make a decison or

provide information. This information should be indicated on the data sheets (see annex A).

4.1.2 The equipment (including auxiliaries) covered by this International Standard shall be designed and

constructed for a minimum service life of 20 years and at least 3 years of uninterrupted operation.

4.1.3 Unless otherwise specified, the compressor vendor shall assume unit responsibility.

4.1.4 The compressor shall be designed to deliver required head and capacity at the normal operating point

without negative tolerance. The input power at the above condition shall not exceed 104 % of the predicted value

for this point.

NOTE See the optional performance test criteria in 6.3.6.2 and handling of excess head for constant speed drivers.

4.1.5 The head versus capacity characteristic curve (see Figure 1) shall rise continuously from the rated point to

the predicted surge. The compressor, without the use of a bypass, shall be suitable for continuous operation at any

capacity at least 10 % greater than the predicted approximate surge capacity shown in the proposal.

4.1.6 Cooling water systems, if required, shall be designed for the conditions specified in Table 1 unless

otherwise specified. Provision shall be made for complete venting and draining of the system.

The vendor shall notify the purchaser if the criteria for minimum temperature rise and velocity over heat exchange

surfaces result in a conflict. The criterion for velocity overheat exchange surfaces is intended to minimize the use of

cooling water. The purchaser shall approve the final selection.

4.1.7 The arrangement of the equipment, including piping and auxiliaries, shall be developed jointly by the

purchaser and the vendor. The arrangement shall provide adequate clearance areas and safe access for operation

and maintenance.

SIST EN ISO 10439:2004
ISO 10439:2002(E)

The head versus capacity curve at 100 % speed shall extend to at least 115 % capacity of the CRP. Head versus capacity curves

at other speeds shall be extended to equivalent capacity at each speed. For example, the head versus capacity curve at 105 %

speed shall be extended to 1,05 times 1,15 times capacity of the CRP; the head versus capacity curve at 90 % speed shall be

extended to 0,9 times 1,15 times capacity at the CRP; and so on. These points define the “approximate capacity limit” curve.

Except where specific numerical relationships are stated, the relative values implied in this figure are assumed values for

illustration only.

The 100 % speed is determined from the operating point requiring the highest head — point A in the illustration.

The compressor rated point (CRP) is the intersection on the 100 % speed line corresponding to the highest flow of any

operating point — point C in the illustration.

Refer to the applicable standard for the compressor driver (e.g. ISO 10437 or ISO 3977-5) for trip speed and minimum

operating speed limits.
See 4.9 for allowable margins of critical speeds to operating speeds.

The maximum continuous speed shall be 105 % for variable speed drivers. The maximum continuous speed shall be the

speed corresponding to the synchronous speed of the motor.

specified by the purchaser. These conditions shall include whether the installation is indoors (heated or unheated)

or outdoors (with or without a roof), maximum and minimum temperatures, unusual humidity, and dusty or corrosive

conditions. For the purchaser's guidance, the vendor shall list in the proposal any special protection that the

purchaser is required to supply.

4.1.11 Control of the sound pressure level (SPL) of all equipment furnished shall be a joint effort of the purchaser

and the vendor. The equipment furnished by the vendor shall conform to the maximum allowable sound pressure

level specified by the purchaser.

z 4.1.12 The purchaser shall advise the vendor of any requirements for liquid injection.

4.1.13 Equipment shall be designed to run without damage to the trip speed and the maximum allowable working

pressure.

4.1.14 The machine and its driver shall perform on the test stand and on their permanent foundation within the

specified acceptance criteria. After installation, the performance of the combined units shall be the joint

responsibility of the purchaser and the vendor having unit responsibility.

4.1.15 Many factors (such as piping loads, alignment at operating conditions, supporting structure, handling during

shipment, and handling and assembly at site) may adversely affect site performance. To minimize the influence of

these factors, the vendor shall review and comment on the purchaser's piping and foundation drawings. If

specified, the vendor's representative shall
a) observe a check of the piping performed by parting the flanges,
b) check alignment at the operating temperature, and
c) be present during the initial alignment check.

z 4.1.16 Motors and all other electrical components and installations shall be suitable for the area classification

and shall comply with applicable local codes and regulations specified by the purchaser.

4.1.17 Spare parts for the compressor and all furnished auxiliaries shall meet all the criteria of this International

Standard.

International Standard.

z 4.1.21 The purchaser and the vendor shall agree on the measures to be taken in order to comply with

governmental regulations, ordinances or rules that are applicable to the equipment.

shall include at least a 3 mm corrosion allowance. The thickness of the casing shall not be less than that calculated

in accordance with the pressure design code.
