Each member body interested in a subject for which a technical committee has been Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The main task of technical committees is to prepare International Standards. Draft International Standards adoptedbythetechnicalcommitteesarecirculatedtothememberbodiesforvoting.Publicationasan 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 SC 12, Soldering materials. Iso 9455 consists of the following 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 and detection of halide (excluding fluoride) content Part 8: Determination of zinc content Part 9: Determination of ammonia content Part10:Flux efficacytest, solder spread methoa Part 11: Solubility of flux residues Part 13: Determination of flux spattering Part 14: Assessment of tackiness of flux residues Part15:Coppercorrosiontest Part16:Fluxefficacytests,wettingbalancemethod Part 17: Surface insulation resistance comb test and electrochemical migration test of flux residues Requests for official interpretations of any aspect of this part of isO 9455 should be directed to the Secretariat of ISO/TC44/SC12viayour national standards body.Acompletelistingof thesebodiescanbefound atwww.iso.org @ ISO 2012 -All rights reserved
