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 9455-10 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee

INTERNATIONAL STANDARD ISO 9455-10:2012(E)
Soft soldering fluxes — Test methods —
Part 10:
Flux efficacy test, solder spread method
1 Scope
This part of ISO 9455 specifies a method for the determination of the efficacy of a soft soldering flux. The method
is known as the solder spread method of filler metal and is applicable to all flux classes defined in ISO 9454-1.
NOTE An alternative method for the determination of the flux efficacy, applicable to liquid fluxes only, known as the
[3]
wetting balance method, is specified in ISO 9455-16.

4 Principle
A specially prepared brass test sheet is treated with a known quantity of the flux under test and a standard
quantity of specified solder alloy. Upon heating, the solder alloy melts and spreads across the surface of the
brass test sheet, the extent of spread being a measure of the flux efficacy. The area covered by the solder is
determined by means of a planimeter or other suitable technique.
ISO 9455-10:2012(E)
This test method is applicable to all fluxes. If required, the efficacy of the flux sample under test can be
compared with that of a standard flux (see Annex A).
NOTE It is possible to use copper as the test surface. However, it is preferable to use brass as the test surface in
order to distinguish between various fluxes because it provides a better surface for differentiation than copper does.
5 Reagents
Use only reagents of recognized analytical grade and distilled or demineralized water or water of equivalent purity.
5.1 Acid preparation solution, prepared in a fume cupboard by cautiously mixing the following ingredients
in the order given, cooling as necessary.
— 140 ml water;
— 225 ml nitric acid (ρ = 1,42 g
