19、ldwide federation of national standards bodies (ISO member bodies). The work of preparing International 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
20、 that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this d
21、ocument and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Direc

26、ons for filler materials for soldering and brazing, on the basis of their chemical composition. For brazing materials only, the designation includes their solidus/liquidus temperatures. This International Standard deals with the metallic part of filler materials used in soldering and brazing product
27、s, e.g. foils, wires, rods, pastes, flux coated rods/wires, flux cored rods/wires, etc.2 Symbols and requirements2.1 GeneralThe designation is divided into two parts for soldering filler metals and three parts for brazing filler metals. In each case, the parts are separated by a dash.2.2 First part
28、(applicable to all materials)The first part consists of a letter denoting the type of use of the material, as follows:a) “S” shall be used for all soldering filler metals;b) “B” shall be used for all brazing filler metals.NOTE For solders for electronic applications, see also 2.3.6.2.3 Second part (
29、applicable to all materials)2.3.1 The second part consists of a group of symbols, in accordance with the classification given in 2.3.2 to 2.3.6, indicating the various metals or metalloids making up the filler metal.2.3.2 The chemical symbol of the major element in the filler metal is placed first.
30、This is followed by the nominal mass percentage of the element concerned. This value shall be expressed as a whole number with an accuracy of 1.When a range is specified for an element in the alloy, the nominal value to be used in the designation should be the mean of the range, rounded to the neare
31、st whole number, or rounded to the nearest even number if the mean is halfway between two whole numbers. When only a minimum value is specified, however, the rounded-off minimum percentage should be used as the nominal value in the designation.2.3.3 The chemical symbols of the other metals or metall
32、oids specified in the alloy are given in decreasing order of their nominal percentage. In addition, for soldering filler metals only, each chemical symbol shall be followed by the nominal mass percentage of the element concerned (see 2.3.2). If two or more elements have the same nominal mass percent
33、age they shall be classified in order of decreasing atomic number.2.3.4 Metals or metalloids with a nominal specified value (see 2.3.2) less than 1 % by mass shall not be indicated in the designation, unless these elements are functional components of the alloy; in which case, they shall be indicate
34、d by:a) for soldering filler metals, their chemical symbols only;EN ISO 3677:2016 (E) DIN EN ISO 3677:2016-12 5 b) for brazing filler metals, their chemical symbols enclosed in parentheses.2.3.5 Only the chemical symbols of the first six constituents shall be indicated.2.3.6 For solders for electron
35、ic applications, the letter “E” shall be added immediately after the second part.2.4 Third part (for brazing filler metals only)The third part indicates the temperatures, expressed in degrees Celsius, at the beginning and end of solidification. The solidus temperature shall be placed first, followed
36、 by the liquidus temperature. The temperatures shall be separated by an oblique stroke (slash).3 Examples3.1 Solders3.1.1 A tin-base alloy (60 %) with 39 % lead and 0,4 % antimony, with a solidus/liquidus temperature of S 183 CL 191 C, shall be designated as follows:S-Sn60Pb40Sb3.1.2 A tin-base allo
37、y (63 %) with 37 % lead of high purity, for use in special applications (e.g. in the electronics industry), with a melting temperature of 183 C shall be designated as follows:S-Sn63Pb37E3.2 Brazing filler materials3.2.1 A binary eutectic filler metal with 72 % silver and 28 % copper, with a melting
38、temperature of 780 C, shall be designated as follows:B-Ag72Cu-780A similar alloy, but containing lithium (less than 1 %) as a functional element, shall be designated as follows:B-Ag72Cu(Li)-7803.2.2 A nickel-base filler metal (63 %) with 16 % tungsten, 10 % chromium, 3,8 % iron, 3,2 % silicon, 2,5 %
39、 boron, 0,5 % carbon, 0,6 % phosphorus, 0,1 % manganese and 0,2 % cobalt, with a solidus/liquidus temperature of S 970 CL 1105 C shall be designated as follows:B-Ni63WCrFeSiB-970/11053.2.3 A copper-base alloy (59 %) with 40 % zinc, 0,5 % tin, 0,2 % silicon, 0,2 % manganese and 0,1 % nickel, with a solidus/liquidus temperature of S 850 CL 885 C, shall be designated as follows:B-Cu59Zn-850/885EN ISO 3677:2016 (E) DIN EN ISO 3677:2016-12 6
