Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0
member bodies). The work of preparing International Standards is normally carried out through IS0 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. IS0 collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
L
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.
International Standard IS0 12224-1 was prepared by Technical Committee lSO/TC 44, We/ding and allied
processes, Subcommittee SC 12, Soldering and brazing materials.
IS0 12224 consists of the following parts, under the general title Solder wire, so/id and flux cored - Specification
and test methods:
- Part I: Classification and performance requirements
- Part 2: Determination of flux content
- Part 3: Wetting balance test
Annexes A and B form an integral part of this International Standard. Annexes C and D are for information only.

Solder wire, solid and flux cored - Specification and test
methods -
Part 1:
Classification and performance requirements
1 Scope
This part of IS0 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.
2 Normative references

3 Classification and designation
3.1 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 IS0 9453.
3.2 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 IS0 9454-l.
3.3 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 IS0 12224 (i.e. IS0 12224-1 j;
the appropriate soft solder alloy designation in accordance with IS0 9453;
W
in the case of flux cored solder wire, the appropriate flux classification in accordance with IS0 9454-l.
C>
The three parts of the designation shall be separated by an oblique stroke (/).
EXAMPLE 1
A solid wire, conforming to this part of IS0 12224, in 60/40 tin/lead solder, is designated as follows:
IS0 122249l/S-SnGOPb40
EXAMPLE 2
A flux cored solder wire, conforming to this part of IS0 12224, consisting of 60/40 tin/lead solder having a core of
halide activated colophony flux, is designated as follows:
IS0 12224-l/S=SnGOPb40/1 .I .2
4 Requirements
4.1 Solder alloy composition of solid and flux cored solder wire
Solid solder wire shall conform to the requirements for the appropriate alloy given in IS0 9453.
