A complete listing of these bodies can be found at www.iso.org.DIN EN ISO 17672:2017-01 EN ISO 17672:2016 (E)4 1 ScopeThis International Standard specifies the compositional ranges of a series of filler metals used for brazing. The filler metals
31、are divided into seven classes, related to their composition, but not necessarily to the major element present.NOTE 1 For the major element(s) present, see Annex A.In the case of composite products, such as flux-coated rods, pastes or plastics tapes, this International Standard covers only the fille
32、r metal that forms parts of such products. The melting temperatures given in the tables are only approximate, as they necessarily vary within the compositional range of the filler metal. Therefore, they are given only for information. Technical delivery conditions are given for brazing filler metals
33、 and products containing brazing filler metals with other constituents such as flux and/or binders.NOTE 2 For some applications, e.g. precious metal jewellery, aerospace and dental, filler metals other than those included in this International Standard are often used and these are covered by other I
34、nternational Standards to which reference can be made.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest ed
35、ition of the referenced document (including any amendments) applies.ISO 3677, Filler metal for soft soldering and braze welding DesignationISO 80000-1:2009, Quantities and units Part 1: General3 CompositionThe filler metal shall have a composition in accordance with Tables 5 to 13 for the particular
36、 type, except as modified for special vacuum requirements (see Clause 4 and Table 1).If the values for an element range from 0 () to a defined value, the element may be, but does not have to be, in that brazing filler metal.For the purposes of determining compliance with composition limits, any valu
37、e obtained from the analysis shall be rounded to the same number of decimal places as used in this International Standard in expressing the specified limit. The following rules shall be used for rounding.a) When the figure immediately after the last figure to be retained is less than five, then the
38、last figure to be retained shall be kept unchanged.b) When the figure immediately after the last figure to be retained is either1) greater than five, or2) equal to five and followed by at least one figure other than zero,the last figure to be retained shall be increased by one.c) When the figure imm
39、ediately after the last figure to be retained is equal to five, and followed by zeros only, then the last figure to be retained shall be left unchanged if even, and increased by one DIN EN ISO 17672:2017-01 EN ISO 17672:2016 (E)5 if odd. For the purposes of determining compliance with the requiremen
40、ts of this International Standard, the actual test values obtained shall be subjected to the rounding-off instructions given in ISO 80000-1:2009, Annex B.NOTE The chemical analysis is of the bulk material, but the material can be composed of discrete powders with different individual compositions or
41、 multiple layers of roll-clad foils where each layer can have a different individual composition.4 Special vacuum requirementIn a few instances, which are most likely to apply to Ag 272, Pd 287, Pd 387, Pd 388, Pd 481, Pd 483, Pd 484, Pd 587, Pd 647 and Au 295, Au 375, Au 625, Au 752, Au 801 and Au
42、827, lower impurity limits can be required for brazing in vacuum or service in vacuum and these limits shall be as given in Table 1.Filler metals complying with Table 1 shall have the letter V added as a suffix to the codification plus the digit 1 or 2 to indicate the grade.NOTE Grade 1 is intended
43、for the most demanding duties, Grade 2 for less demanding.Table 1 Impurity limits for special vacuum requirementsImpurityLimit % by mass max.Grade 1 Grade 2Ca0,005 0,005Cd 0,001 0,002P 0,002 0,002bPb 0,002 0,002Zn 0,001 0,002Mnc0,001 0,002Inc0,002 0,003All other elements where vapour pressure at 500

45、S, Sb, Se, Sr, Te and Tl. For such elements (including Cd, Pb and Zn), the total is limited to 0,010 %.5 Chemical analysisChemical analyses shall be carried out by any suitable method, but it should be noted that in the case of many brazing alloys, the use of reference standards may be essential, as
46、 agreed between the purchaser and the supplier. Analysis is only required to be carried out routinely for those elements for which specific limits are shown. If, however, the presence of other elements is suspected or in the course of routine analysis is indicated to be in excess of the limits laid
47、down for unnamed elements, or would bring the total of impurities above the specified limit, further analyses shall be carried out for such elements.DIN EN ISO 17672:2017-01 EN ISO 17672:2016 (E)6 6 DesignationThe filler metal shall be designated by the description “filler metal,” reference to this
48、International Standard (i.e. ISO 17672) and a code. Details of the two options for the code system used are given in Annex A.As an example, the designations of an aluminium filler metal containing 11 % to 13 % Si, in accordance with this International Standard, can be made in one of the following ways:EXAMPLE 1 Filler metal ISO 17672-Al 112where“Filler metal” is the description;“ISO 17672” is the reference to this International Standard;“Al 112” is the
