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

30、KY, Naval Air Warfare Center Aircraft Division, Lakehurst, New JerseyU.S. DEPARTMENT OF THE AIRFORCE JEFFREY CALCATERRA, US Airforce Systems Support Division, Dayton, OhioANSI H35.2(M)20176ForewordThis Standard is a revision of ANSI H35.2(M)-2013, which consists of logical values for long-term metri
31、c use rather than a restatement 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 correct
32、ions and clari cation to 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 e
33、dges, or is a regular hexagon 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 su
34、pplied in coiled form, 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
35、for international harmonization). 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.
36、Forging stock is typically a cast product or an extruded product.PipeTube in standardized combinations of 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
37、not less than 6.3 mm and with sheared or sawed edges. (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 a
38、ppropriate pattern, to provide improved traction. 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”
39、 is no longer recommended.Structural Pro leA pro 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
40、lengths. In North America, the minimum diameter 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 “
41、Pro le” is preferred. See “Pro le.”SheetGenerally, 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 th
42、is thickness range are supplied to sheet product 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 l
43、ayer or layers anodic to the core, on one or both 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 b
44、onded layer or layers of a low melting temperature 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. C
45、ross-sections are in the shape of circles, ovals, 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
46、of sheet.Heat-Exchanger TubeA tube used in an apparatus 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, typic
47、ally of formed sheet. Welded tube can be fabricated 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,
48、 or is round, hexagonal, or octagonal. In North 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
49、 supplied in coiled form; if supplied in straight 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 . . . . . . . mul
