Foreword
IS0 (the International Organization for Standardization) is a worldwide fed-
eration 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.
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 9455-l 5 was prepared by Technical Com-
mittee lSO/TC 44, Welding and allied processes, Subcommittee SC 12,
Soldering and brazing materials.
IS0 9455 consists of the following parts, under the general title Soft
soldering fluxes - Test methods:
Part ? : Determination of non-volatile matter, gravime tric method
- Part 2: Determination of non-volatile matter, ebulliometric method
Part 6: De term&a Con of halide (excluding fluoride) content
Part 8: Determination of zinc con tent
Part 9: Determination of ammonia content
Part ? 0: Flux efficacy tests, solder spread method
- Part ? 1: Solubility of flux residues
- Part 12: Steel tube corrosion test
