ISO INTERNATIONAL 9455-8 STANDARD First edition 1991-12-15 Soft soldering fluxes --- Test methods Part 8: Determination of zinc content Flux de brasage tendre -- Methodes d'essai -- Partie 8: Dosage du zinc Reference number ISO 9455-8:1991(E) Copyright International Organization for Standardization Not for Resale ISO 9455-8:1991(E) Foreword tsoO (the International Organization for Standardization) is a worldwide federation of national standards bodies (lsO member bodies).The work of preparing Internationat 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, govern- mental and non-governmental, in liaison with isO, aiso take part in the work. Iso 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 lnter- bodies casting a vote. International Standard isO 9455-8 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Sub-Committee SC 12, Soldering and brazing materials. isO 9455 consists of the foliowing parts, under the general title Soft soldering fluxes --- Test methods: Part 1: 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 10: Flux efficacy tests, solder spread method Part 11: Solubility of flux residues Part 12: Steel tube corrosion test C IsO 1991 permission in writing from the publisher.
