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 10628-2 was prepared by Technical Committee ISO/TC 10, Technical product documentation, Subcommittee
SC 10, Process plant documentation.
This first edition of ISO 10628-2, along with ISO 10628-1 (under preparation), cancels and replaces
ISO 10628:1997, which has been technically revised.
ISO 10628 consists of the following parts, under the general title Diagrams for the chemical and
petrochemical industry:

Graphical symbols for diagrams used in chemical and petrochemical industry are presented in Table 2, which
is is divided into four columns, as follows:
1 Item no. Consecutive numbering within each subject group according to Table 1
2 Reg. no. Registration numbers structured as follows:
nnn Registration number for ISO 14617 graphical symbols.
Cnnnn Preliminary registration number for a new graphical
symbol, which will be implemented in ISO 14617. The
preliminary registration number will be replaced with the
final ISO 14617 registration number at first periodical review
of ISO 10628-2.
X2nnn Registration number for ISO 14617 symbol examples.
X8nnn Registration number for ISO 10628-2 symbol examples.
3 Graphical symbol Graphical symbols shown with a 2,5 mm dotted grid behind. Preferred
locations of connections at graphical symbols are indicated by “—”. This
is not a part of the graphical symbol.
4 Description The preferred descriptors for the graphical symbol.
Rules for modification of proportions and orientation of graphical symbols are given in ISO 81714 and IEC 81714.
If a graphical symbol is not accessible in ISO 10628-2, then ISO 14617 should be consulted for the needed
graphical symbol.

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 10628-2 was prepared by Technical Committee ISO/TC 10, Technical product documentation,
Subcommittee SC 10, Process plant documentation and tpd-symbols.
This edition of ISO 10628-1 and ISO 10628-2 replace the first edition of ISO 10628:1997 of which has been
technically revised.
ISO 10628 consists of the following parts, under the general title Diagrams for chemical and petrochemical
industry:
Part 1: Specification of diagrams
Part 2: Graphical symbols

DRAFT INTERNATIONAL STANDARD ISO/DIS 10628-2
Diagrams for the chemical and petrochemical industry —
Part 2:
Graphical symbols
1 Scope
This International Standard defines graphical symbols for the preparation of flow diagrams for process plants.
This part of ISO 10628 is a collective application standard of the ISO 14617 series.
These diagrams represent the configuration and function of process plants and form integral parts of the
complete technical documentation necessary for planning, mechanical engineering, erecting, managing,
commissioning, operating, maintaining and decommissioning of a plant.
This International Standard does not apply to electrotechnical diagrams, see IEC 61617.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO ab-c:199x, General title of series of parts — Part c: Title of part
ISO xyz (all parts), General title of the series of parts
3 Terms and definitions
For the purposes of this International Standard, the definitions given in ISO 14617, ISO 10628-1 and
ISO 10209-1.
4 Structure of graphical symbols
The graphical symbols are grouped according to functional and/or design features. The first symbols are
symbols of basic nature followed by application examples (see Table 1).
The registration numbers refer to ISO 14617.
The graphical symbols for modifications are given in Table 2.
