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 44, Welding and allied processes,
Subcommittee SC 12, Soldering and brazing materials.
This second edition cancels and replaces the first edition (ISO 12224-1:1997), which has been
technically revised.
The main changes compared to the previous edition are as follows:
— in Table 1 greater nominal contents were added;
— 5.5 and Table 3 were deleted because the spread test is not commonly used;
— 5.6.1 was deleted because the test method was withdrawn;
— in 6.1 the reference to ISO 10564, which was withdrawn, was replaced by a recommended method;
— the designations were aligned with ISO 9454-1:2016;
A list of all parts in the ISO 12224 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Solder wire, solid and flux cored — Specification and test
methods —
Part 1:
Classification and performance requirements
1 Scope
This part of ISO 12224 specifies a coding system for the classification and designation of solid and flux
cored solder wire, and the performance requirements to be met by flux cored wire and its constituents.
Requirements for sampling, labelling and packaging are also specified.
Annex A specifies a method for the solvent extraction of flux incorporated in flux cored solder wire. The
solution so obtained may be used for testing purposes.
Annex B specifies the method for measuring the mean diameter of flux cored solder wire.
Annex C gives guidance on the test methods appropriate for the flux types incorporated in flux cored
solder wire.

4 Classification and designation
4.1 Solder alloy designation
The solder alloy used for solid wire, and for the solder component of flux cored solder wire, shall be
designated in accordance with the solder alloy designations given in ISO 9453.
4.2 Flux classification
The flux component of flux cored solder wire shall be classified in accordance with the system, based
on the main fluxing ingredients, given in ISO 9454-1.
4.3 Designation of flux cored solder wire
The designations for solid and flux cored solder wire shall consist of the following parts:
a) reference to this part of ISO 12224 (i.e. ISO 12224-1);
b) the appropriate soft solder alloy designation in accordance with ISO 9453;
c) in the case of flux cored solder wire, the appropriate flux classification in accordance with
ISO 9454-1.
The three parts of the designation shall be separated by an oblique stroke (/).
EXAMPLE 1 A solid solder wire, which corresponds to ISO 12224-1, made of 99,3/0,7 tin-copper soft solder, is
designated as follows:
ISO 12224-1/Sn99,3Cu0,7
EXAMPLE 2 A flux filled solder wire, which corresponds to ISO 12224-1, made of 99,3/0,7 tin-copper soft
solder with a halogen-activated rosin filling, is designated as follows:
ISO 12224-1/Sn99,3Cu0,7/1 123
5 Requirements
5.1 Solder alloy composition of solid and flux cored solder wire
Solid solder wire shall conform to the requirements for the appropriate alloy given in ISO 9453.
The solder component of flux cored solder wire shall conform to the requirements for the appropriate
alloy given in ISO 9453.
5.2 Flux composition of flux cored solder wire
After extraction from a sample of the flux cored solder wire, using the method given in Annex A, the
flux composition shall conform to the requirements for the appropriate flux type given in ISO 9454-1.
5.3 Flux content
