1、ANSI H35.2(M)-2013 Revision of H35.2(M)-2009 American National Standard Dimensional T olerances for Aluminum Mill Products SecretariatThe Aluminum AssociationIncorporatedAmerican National Standard Approval of an American National Standard requires verification by ANSI that the requirements for due p
2、rocess, 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 agreement has been reached by directly and materially affected interests. Substantial agreement means much mo
3、re than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyo
4、ne, whether he has approved the standards or not, from manufac- turing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will under no circumstances give an interpretation of a
5、ny American Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for interpretation should be addressed to the secretariat or sponsor whose name appears on the ti

The procedures of the American National Standards Institute require that action be taken to reaffirm, revise, or withdraw this standard no later than five years from the date of approv

18、a restatement of ANSI H35.2 in metric terms. This latest (2013) revision consists of modification to the column headings and pipe size units for extruded and drawn pipe to harmonize with ANSI/ASME standard; clarification on tolerance calculation for wall thickness (eccentricity) of extruded tube; an
19、d clarifications to table headings and footnotes.ANSI H35.2(M)2013 7 1. Definitions barA solid wrought product that is long in relation to its cross section which is square or rectangular (excluding plate and flattened wire) with sharp or rounded corners or edges, or is a regular hexagon or octagon,
20、 and in which at least one perpendicular distance between parallel faces is over 10 mm. Fin StockCoiled sheet or foil in specific alloys, tempers, and thickness ranges suitable for manufacture of fins for heat-exchanger applications. FoilGenerally, a rolled product rectangular in cross section of th
21、ickness equal to or less than 0.2 millimeters (Formerly 0.15 mm, changed to 0.2 mm for international harmonization). There is an overlap in the thickness range 0.15-0.2 mm defined for foil and sheet. Foil products in this gage range are supplied to foil product specifications. Forging StockA wrought
22、 or cast rod, bar or other section suitable for forging. PipeTube in standardized combinations of outside diameter and wall thickness, commonly designated by “Nominal Diameter” and “ANSI Schedule Numbers.” (Note: Larger sizes usually greater than 25 millimetres are typically extruded while smaller s
23、izes are typically drawn.) PlateA rolled product that is rectangular in cross section and with thickness over 6.3 millimetres and with sheared or sawed edges. Tread PlateSheet or plate having a raised figured pattern on one surface to provide improved traction. ProfileA wrought product that is long
24、in relation to its cross-sectional dimensions which is of a form other than that of sheet, plate, rod, bar, tube, wire or foil. Structural ProfileA profile in certain standard alloys, tempers, sizes, and sections, such as angles, channels, tees, zees, I-beams, and H-sections, commonly used for struc
25、tural purposes. For channels and I-beams there are two standards, namely Aluminum Association Standard and American Standard. RodA solid wrought product over 10 mm in diameter that is long in relation to cross section and over 10 millimetres in diameter. ShapeThis term is no longer recommended. The
26、term “Profile” is preferred. See “Profile.” SheetGenerally, a rolled product that is rectangular in cross section with thickness greater than 0.15 millimeters and less than 6.3 millimeters and with slit, sheared or sawed edges. there is an overlap in the thickness range 0.15-0.2 mm defined for foil
27、and sheet. Sheet products in this gage range are supplied to sheet product specifications. Alclad SheetComposite sheet comprised of an aluminum alloy core having on both surfaces (if one side only, Alclad One Side Sheet) a metallurgically bonded aluminum or aluminum alloy coating that is anodic to t
28、he core, thus electrolytically protecting the core against corrosion. brazing SheetSheet of a brazing alloy, or sheet clad with a brazing alloy on one or both sides. Duct SheetCoiled or flat sheet in specific tempers, widths and thicknesses, suitable for duct applications. TubeA hollow wrought produ
29、ct that is long in relation to its cross section, which is symmetrical and is round, a regular hexagon or octagon, elliptical, or square or rectangular with sharp or rounded corners, and that has uniform wall thickness except as affected by corner radii. Heat-Exchanger TubeA Tube裕for use in apparatu
30、s in which fluid inside the tube will be heated or cooled by fluid outside the tube. The term usually is not applied to coil tube or tubes for use in refrigerators or radiators. (Note: This product is typically seamless drawn tube.) Welded TubeA tube produced by forming and seam- welding sheet longi
31、tudinally. 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, and whose diameter or greatest perpendicular distance between parallel faces is up through 10 millimetres
32、. 2. Standard Limits for Expressing Tolerances 2.1 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 de
33、cimals as follows (except for foil): Tolerance less than 0.050 mm multiple of 0.005 mm Tolerance over 0.050 mm thru 0.50 mm .multiple of 0.01 mm Tolerance over 0.50 thru 1.00 mm multiple of 0.02 mm Tolerance over 1.00 mm .multiple of 0.05 mm For measurements commonly made with instruments not permit
34、ting such accuracy, standard dimensional tolerances are expressed as follows: Tolerance up thru 5 mm .multiple of 0.5 mm Tolerance over 5 mm thru 50 mm . multiple of 1 mm Tolerance over 50 mm multiple of 5 mm 2.2 Rounding For purposes of determining conformance to the dimensional tolerances, a measu
35、red value is not rounded off. To determine applicable limits when a dimension is specified to more decimal places than are used in these standards, it shall be rounded off to the same number of places in conformance with ASTM E29, Standard Practice for Using Significant Digits in Test Data to Determ
