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 com-
mittee 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 stan-
dardization.
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 Stan-
dards 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.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of normative document:
— an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical ex-
perts in an ISO working group and is accepted for publication if it is approved by more than 50%
of the members of the parent committee casting a vote;
— an ISO Technical Specification (ISO/TS) represents an agreement between the members of a tech-
nical committee and is accepted for publication if it is approved by 2/3 of the members of the
committee casting a vote.
An ISO/PAS or ISO/TS is reviewed every three years with a view to deciding whether it can be trans-
formed into an International Standard.
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/TS 15926-8 was prepared by Technical Committee ISO/TC 184, Automation systems and integra-
tion, Subcommittee SC 4, Industrial data.
ISO 15926 is organized as a series of parts, each published separately. The structure of ISO 15926 is
described in ISO 15926-1.
Each part of ISO 15926 is a member of the following series: data model, reference data, implementa-
tion methods, conformance testing methodology and framework, characterization methods, abstract test
suites. This part of ISO 15926 is a member of the implementation methods series.

Introduction
ISO 15926 is an International Standard for the representation of process plant life-cycle information.
This representation is specified by a generic, conceptual data model that is suitable as the basis for
implementation in a shared database or data warehouse. The data model is designed to be used in
conjunction with reference data: standard instances that
