9、odies). 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 a
10、nd 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 b
11、odies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Intemational Standard IS0 9455-1 O was prepared by Technical Committee ISOTC 44, Welding and allied processes, subcommittee SC 12, Soldering and brazing materials. IS0 9

17、flux. The method is known as the solder spread method and is applicable to all flux classes defined in IS0 9454-1, NOTES 1 This part of IS0 9455 is only applicable for liquid fluxes 10 % ( m h ) . 2 An alternative method for the determination of the flux efficacy, applicable to liquid fluxes only, k
18、nown as the wetting balance method, is specified in IS0 9455-16. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of IS0 9455. At the time of publication, the editions indicated were valid. All standards are s
19、ubject to revision, and parties to agreements based on this part of IS0 9455 are encouraged to investigate the possibility of applying the most recent edition of the standards indicated below. Members of IEC and IS0 maintain registers of currently valid International Standards. IS0 197-1 :1983, Copp

22、 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. Th
23、is 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
24、between various fluxes because it provides a better surface for differentiation than copper would. 1 Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=NASA Technical Standards 1/9972545001 Not for Resale, 04/22/2007 21:44:30 MDTNo reproduction o
