7、he International Organization 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 commit
8、tee has been established 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 electrotech
9、nical standardization. International 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
10、 bodies for voting. Publication 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
11、 any or all such patent rights. ISO 6362-1 was prepared by Technical Committee ISO/TC 79, Light metals and their alloys, Subcommittee SC 6, Wrought aluminium and aluminium alloys. This second edition cancels and replaces the first edition (ISO 6362-1:1986), which has been technically revised. ISO 63

24、rod/bar solid wrought product of uniform cross-section along its whole length, supplied in straight lengths NOTE 1 Rod is normally less than 6 mm in diameter or minor dimension. NOTE 2 In North America, the minimum diameter of a rod is 9,525 mm (0,375 in). Below this limit the product is called wire
25、. NOTE 3 The cross-sections are in the shape of circles, squares, rectangles or regular hexagons. Products with a square, rectangular or hexagonal cross-section may have corners rounded along their whole length. NOTE 4 For rectangular bars, the thickness exceeds one-tenth of the width. The term “rec
26、tangular bar” includes “flattened circles” and “modified rectangles”, of which two opposite sides are convex arcs, the other two sides being straight, of equal length and parallel. 3.2 tube hollow wrought product of uniform cross-section with only one enclosed void along its whole length, and with a
27、 uniform wall thickness, supplied in straight lengths or in coiled form, provided the inner and outer cross- sections are concentric and have the same form and orientation NOTE The cross-sections are in the shape of circles, squares, rectangles or regular hexagons. Hollow products with square, recta
28、ngular or regular hexagonal cross-sections may have corners rounded along their whole length. 3.3 profile wrought product of uniform cross-section along its whole length, with a cross-section other than rod/bar, tube, sheet or strip, supplied in straight lengths or in coiled form and where the produ
29、ct is long in relation to its cross- sectional dimensions NOTE According to the form of its cross-section, it is called: a) hollow profile: the cross-section includes either one enclosed void, provided that the cross-section is other than tube, or more than one enclosed void; b) solid profile: the c
30、ross-section does not include any enclosed void. 3.4 inspection lot consignment, or a part thereof, submitted for inspection, comprising products of the same grade or alloy, form, temper, size, shape, thickness or cross-section and processed in the same manner 2 ISO 2012 All rights reserved ISO 6362
