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.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www.iso.org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation on the meaning of ISO specific terms and expressions related to conformity

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers

to Trade (TBT) see the following URL: Foreword - Supplementary information

The committee responsible for this document is ISO/TC 10, Technical product documentation,

Subcommittee SC 10, Process plant documentation.

This first edition of ISO 10628-1, along with ISO 10628-2, cancels and replaces ISO 10628:1997, which

has been technically revised.

ISO 10628 consists of the following parts, under the general title Diagrams for chemical and petrochemical

industry:

4 Classification, information content, and presentation of flow diagrams
4.1 General

Flow diagrams show the structure and function of the process plants and are part of the entire set

of technical documents which are required for planning, assembly, construction, management,

commissioning, operation, maintenance, shutdown, and decommissioning of a plant.

Flow diagrams are a means by which information is exchanged between parties involved in the

construction, assembly, operation, and maintenance of such process plants. General rules and

recommendations for preparation of flow diagrams are given in ISO 15519.

SIST EN ISO 10628-1:2015
ISO 10628-1:2014(E)

Depending on the information required, a distinction should be made between block diagrams, process

flow diagrams, and piping and instrumentation diagrams (P&ID).

Each particular type of flow diagram shall take the functional requirements into consideration.

The graphical presentation shall conform to the rules set down in Clause 5. Flow routes and flow

directions shall be indicated by lines and arrows.

All equipment, machinery, flow lines (e.g. pipelines, transport routes), and valves shall be represented

in accordance with ISO 10628-2.

The measuring, control, and regulating tasks shall be represented in accordance with IEC 62424.

Designation of objects in diagrams could be performed using reference designation according to

IEC 81346 series.
4.2 Block diagrams
4.2.1 General representation rules

The block diagram depicts a process or process plant in simplified form by means of rectangular frames

which are interconnected by flow lines (see Figures A.1 and A.2).
The rectangular frames can represent the following:
— processes;
— process steps;
— unit operations;
— process plants or groups of process plants;
— plant sections;
— equipment.
The flow lines can represent streams of materials or energy flows.
4.2.2 Basic information
The block diagram shall contain at least the following information:
a) denomination of frames;
b) denomination of ingoing and
...
