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 of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO’s adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/
iso/ foreword .html.
This document was prepared by Technical Committee ISO/TC 107, Metallic and other inorganic coatings,
in collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/
TC 240, Thermal spraying and thermally sprayed coatings, in accordance with the Agreement on technical
cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 12671:2012), which has been technically
revised. The main changes compared with the previous edition are as follows:
— the designation examples and figures have been updated in accordance with the latest thermal
spray terminology and material standards (see ISO 14917, ISO 14919 and ISO 14232-1).
Any feedback or questions on this document should be directed to the user’s national standards body. A

INTERNATIONAL STANDARD ISO 12671:2021(E)
Thermal spraying — Thermally sprayed coatings —
Symbolic representation on drawings
1 Scope
This document specifies how the symbolic representation of thermally sprayed coatings is indicated on
drawings.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
No terms and definitions are listed in this document.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at http:// www .electropedia .org/
4 General
Coatings may be indicated with the general recommendations for technical drawings. To apply this
symbolic representation will make sense in cases where the thermally sprayed coating is very thin
and/or can be built up by several dissimilar coatings one upon another.
The symbolic representation shall clearly give all the necessary indications regarding the specific
coating to be obtained without over-burdening the drawing with notes or showing an additional view
or detail enlargement.
This symbolic representation includes an elementary symbol and one or more supplementary symbols
and further complementary indications.
If a large number of instructions for producing the coating have to be mentioned, it is recommended to
indicate the specific instructions on the drawing or to define them in a separate parts’ list, if applicable
(see Figures 6 and 7).
5 Symbols
The elementary symbol shall indicate that this process deals with thermal spraying.
The following information shall be given by supplementary symbols:
— type of coating (bond or top coat);
— the spraying process and subsequent treatments.
The following requirements may be defined by further additional instructions:
— the coating thickness needed or the final coating thickness machined;
— the spray material to be used;
ISO 12671:2021(E)
— the surface condition;
— post-treatments of coating;
— a technical specification that defines the requirements necessary to complete the coating.
6 Position of the symbols on drawings
The complete symbol shall contain:
— the designation of the coating (outside the outline of the component);
— an arrow line;
— a reference line (continuous line) with the elementary symbol above it;
— instructions concerning the mode of coating, spraying process, coating thickness, spray material,
surface condition and post-treatments, if applicable.
The arrow lin
