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, govern-
mental 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 mernber bodies for voting. Publication as an Inter-
national Standard requires approval by at least 75 9/o of the member
bodies casting a vote.
International Standard IS0 9455-12 was prepared by Technical Commit-
tee ISO/TC 44, Welding and allied processes, Sub-Committee SC 12,
Soldering and brazing materials.
IS0 9455 consists of the following parts, under the general title Soft
soldering fluxes - lest methods:
_ Part I: Determination of non-volatile matter, gravimetric method
- Part 2: Determination of non-volatile matter, ebulliometric method
-- Part 3: Determination of acid value, potentiometric and visual
titration methods
- Part 5: Copper mirror test
--
Part 6: Determination of halide content
- Part 8: Determination of zinc content
- Part 9: Determination of ammonia content
-- Part IO: Flux efficacy tests, solder spread method
- Part I I: Soiubility of flux residues
-. Pat-t 12: Steel tube corrosion test
