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.
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.
International Standard ISO 13705 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.
Annexes D and E form a normative part of this International Standard. Annexes A, B, C, F, G and H are for
information only.

Introduction
This International Standard is based on API standard 560, second edition, September 1995.
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.
In International Standards, the SI system of units is used. Where practical in this International Standard, US
Customary units are included in brackets for information.
A bullet (zzzz) 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 (see examples
in annex A) or stated in the enquiry or purchase order. Decisions should be indicated on a check list (see example
in annex B).
