16、tion for Standardization) is a worldwide 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

17、has the right to be represented on 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. In

18、ternational Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publi

19、cation as an 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 r

Test pieces shall be prepared and tested a

28、s specified in Clauses 5 and 6, as well as in the classification standard. The test results shall fulfil the requirements of the classification standard. 4 Test plate material The plate material shall be selected from the range of materials and material thicknesses specified in the classification st

29、andard. The surfaces to be welded shall be free of scale, rust, and other contaminants. 5 Preparation of the test piece 5.1 Before assembly, the web piece of the assembly shall have one edge of the web flat and square throughout its length so that, when the web is set on the flange, which shall be s

30、traight and smooth, there will be intimate contact along the entire length of the joint. The web and flange shall be assembled as shown in Figure 1. Both ends of the joint shall be secured by tack welds to maintain intimate contact along the length of the joint and to maintain the 90 angle between t

31、he web and flange. The web and flange dimensions shall be in accordance with those given in the electrode classification standard.

33、n of fillet weld test piece 5.2 The position of welding and conditions of welding shall be as prescribed in the relevant standard for the classification and size of consumable under test, and as defined in ISO 6947. A single pass fillet weld shall be deposited on one side of the joint for approximat

34、ely the full length of the test piece. The minimum temperature of the assembly shall be 5 C. For covered electrodes, at least one electrode (and as many more as the weld permits) shall be continuously consumed to within the permissible stub length of 50 mm. For electrodes longer than 450 mm, designe

35、d specifically for use in gravity welding, the fillet weld may be made either manually or with a device designed specifically for gravity welding. For wire electrodes, tubular cored electrodes and wires, welding shall be continuous from start to finish of the fillet weld. 5.3 The fillet shall be dep

36、osited using welding speeds compatible with the consumable classification and tested to provide the fillet weld size required by the electrode classification standard. 5.4 If welding of the second side of the test piece is required by the consumable classification standard, the test piece shall be c

37、ooled to room temperature by any convenient means, before starting to weld the second side of the joint.

38、ning welding on the second side. 6 Examination of the test piece 6.1 Throat thickness and leg length shall be measured at a minimum of three points along the length of the weld using an appropriate gauge to demonstrate conformity with the requirements of the classification standard. For covered elec

39、trodes, where two or more electrodes are used, a macrosection, approximately 25 mm wide, shall be removed from a point approximately 25 mm back from the crater end of the deposit made with the first electrode. For continuous consumables and covered electrodes where only one electrode is used, a macr

40、osection, approximately 25 mm wide, shall be removed from approximately the midpoint of the weld length. 6.2 One surface of the macrosection shall be polished, etched, and scribed as shown in Figure 2. The throat, convexity or concavity, and leg lengths of the fillet weld shall be determined to the

41、nearest 0,5 mm by actual measurement of the polished and etched macrosection. If fillet welds are required by the consumable classification standard on both sides of the test piece, then both fillet welds shall be measured on the same macrosection. a) Convex fillet weld b) Concave fillet Size of fil

If, during bending, the weld pulls out of the test plate, it shall be considered as a no test, and the test shall be repeated wi
