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:
— Part 2: Graphical symbols
The following part is under preparation:

Graphical symbols
1 Scope
This part of ISO 10628 defines graphical symbols for the preparation of diagrams for the chemical and
petrochemical industry. It is a collective application standard of the ISO 14617 series.
This part of ISO 10628 does not apply to graphical symbols for electrotechnical diagrams; for these, see IEC 60617.

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.

ISO 10628-2:2012(E)
If the needed graphical symbol is not available in ISO 14617, then the symbol shall be created by combining
ISO 14617 symbols of basic nature with symbols given supplementary information according to rules given in
ISO 14617, ISO 81714 and IEC 81714.
