2、e (ANSI) that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer.Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agree-ment has been reached by directly and materially affected intere

3、sts. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objec-tions be considered, and that a concerted effort be made toward their resolution.The use of American National Standards is completely voluntary; their existen

31、tatement of ANSI H35.2 in metric terms. This latest (2017) revision consists of updated illustrations, removal of footnote 1, changes to the list of de nitions, the addition of the de nition of applicable limits, edits to the de nition of mean wall thickness, editorial corrections and clari cation t

32、o table headings and footnotes. These changes are indicated by highlights in the text.ANSI H35.2(M)20177BarA solid wrought product that is long in relation to its cross section which is square or rectangular (excluding plate and attened wire) with sharp or rounded corners or edges, or is a regular h

33、exagon or octagon, that is typically supplied in straight lengths and in which at least one perpendicular distance between parallel faces is 10 mm or greater. In North America, below this limit the product is called “Wire”. In Europe, bar is supplied in straight lengths; if supplied in coiled form,

34、the product is called “Wire.”Fin StockCoiled sheet or foil suitable and intended for manufacture of ns for heat-exchanger applications.FoilGenerally, a rolled product rectangular in cross section of thickness equal to or less than 0.20 mm (Formerly 0.15 mm, changed to 0.20 mm for international harmo

35、nization). There is an overlap in the thickness range 0.15-0.20 mm de ned for foil and sheet. Foil products in this thickness range are supplied to foil product speci cations.Forging StockA solid product, typically ingot, rod, bar or pro le, intended and suitable for forging. Forging stock is typica

36、lly a cast product or an extruded product.PipeTi riz is f outside diameter and wall thickness. Pipe is commonly designated by “Nominal Diameter” and “ANSI Schedule Numbers.” PlateA rolled product that is rectangular in cross section and with thickness not less than 6.3 mm and with sheared or sawed e

37、dges. (Note: In some international speci cations plate products are de ned as having a thickness not less than 6.0 mm).Tread PlatePlate (or sheet) upon which a pattern has been impressed on one side, by rolling using a specially prepared roll with an appropriate pattern, to provide improved traction

38、. Pro leA wrought product that is long in relation to its cross-sectional dimensions which is of a form other than that of sheet, plate, rod, bar, tube, wire or foil. For pro les sometimes the term “Shape” or “Section” is used, however the term “Shape” is no longer recommended.Structural Pro leA pro

39、 le, rolled or extruded, commonly used for for structural purposes such as angles, channels, H-beams, I-beams, tees, and zees.RodA solid wrought product of circular cross section that is long in relation to its diameter, typically supplied in straight lengths. In North America, the minimum diameter

40、of a rod10 mm; below this limit, the product is called “Wire.” In Europe, rod is supplied in straight lengths and is often called “Round Bar”; if supplied in coiled form, the product is called “Wire.” ShapeThis term is no longer recommended. The term “Pro le” is preferred. See “Pro le.”SheetGenerall

41、y, a rolled product that is rectangular in cross section with thickness greater than 0.15 mm and less than 6.3 mm with slit, sheared or sawed edges. There is an overlap in the thickness range 0.15-0.20 mm de ned for foil and sheet. Sheet products in this thickness range are supplied to sheet product

42、 speci cations. (Note: In some international speci cations sheet products are de ned as having a thickness greater than 0.20 mm and less than 6.0 mm.)Alclad SheetA composite aluminum sheet having an aluminum core and a metallurgically bonded aluminum layer or layers anodic to the core, on one or bot

43、h sides, thus electrolytically protecting the core against corrosion. If only one side is clad, the product is often named “Alclad One Side Sheet.”Brazing SheetSheet of a low melting temperature alloy used for brazing or a clad sheet product having a bonded layer or layers of a low melting temperatu

44、re alloy used for brazing.Duct SheetCoiled or at sheet suitable for duct applications.TubeA hollow wrought product of uniform cross-section with only one enclosed void and with a uniform wall thickness, supplied in straight lengths or in coiled form. Cross-sections are in the shape of circles, ovals

45、, squares, rectangles, equilateral triangles or regular polygons and can have corners rounded, provided the inner and outer cross-sections are concentric and have the same form and orientation. Tube can be formed by extrusion or by forming and joining of sheet.Heat-Exchanger TubeA tube used in an ap

46、paratus in which uid inside the tube will be heated or cooled by uid outside the tube, but the term is typically not applied to coiled tube or to tube for use in refrigerators or radiators. Welded TubeA tube produced by longitudinal seam-welding, typically of formed sheet. Welded tube can be fabrica

47、ted by arc-welding with or without welding wire, high frequency seam welding, or any other type of welding.WireA solid wrought product that is long in relation to its cross section, which is square or rectangular with sharp or rounded corners or edges, or is round, hexagonal, or octagonal. In North

48、America, Dimensional Tolerances for Aluminum Mill Products1. De nitionsANSI H35.2(M)20178the maximum diameter or perpendicular distance between parallel faces of a wire is 10 mm; above this limit the product is called “Rod” or “Bar”. In Europe, wire is supplied in coiled form; if supplied in straigh

49、t lengths, the product is called “Rod” or “Bar.”2. Standard Limits for Expressing Tolerances2.1 Standard limits for expressing the tolerances depend on the type of instrument ordinarily used in measuring the particular dimension. Where instruments permitting the required degree of accuracy generally are used, the tolerances are expressed in decimals as follows (except for foil):Tolerance less than 0.050 mm . . . . . . . multiple of 0.005 mmTolerance over 0.050 thru 0.50
