2、s, 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 more tha
3、n 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 anyone, whe

Requests for interpretation should be addressed to the secretariat or sponsor whose name appears on the title page

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 approval. Purcha

17、 OF THE AIRFORCELarry perkins, US Airforce Systems Support Division, Dayton, OhioANSI H35.2(M)20136ForewordThis Standard is a revision of ANSI H35.2(M)-2009, which consists of logical values for long-term metric use rather than a restatement of ANSI H35.2 in metric terms. This latest (2013) revision
18、 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; and clarifications to table headings and footnotes.ANSI H35.2(M)201371.

19、finitionsbarA 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, and in which at least one perpendicular distance between parallel faces is
20、 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 thickness equal to or less than 0.2 millimeters (Formerly 0.15 mm, changed to 0
21、.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 or cast rod, bar or other section suitable for forging.PipeTube in standardiz

For channels and I-beams there are two standards, namely Aluminum A

ShapeThis term is no longer recommended. The term “Profile” is preferred. See “Profile.”SheetGenerally, a rolled product that is
26、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 and sheet.

28、t 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 product that is long in relation to its cross section, which is symmetrical and is round, a re
29、gular 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 apparatus in which fluid inside the tube will be heated or cooled by fluid outside the tube. The t

(Note: This product is typically seamless drawn tube.)Welded TubeA tube produced by forming and seam-welding sheet longitudinally.WireA solid wrought product that is long in relation to its cross section, which i

Standard Limits for Expressing Tolerances2.1 Standard limits for expressing the tolerance
32、s 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
33、over 0.050 mm thru 0.50 mm .multiple of 0.01 mmTolerance over 0.50 thru 1.00 mm multiple of 0.02 mmTolerance over 1.00 mm .multiple of 0.05 mmFor measurements commonly made with instruments not permitting such accuracy, standard dimensional tolerances are expressed as follows:Tolerance up thru 5 mm
34、.multiple of 0.5 mmTolerance over 5 mm thru 50 mm .multiple of 1 mmTolerance over 50 mm multiple of 5 mm2.2 Rounding For purposes of determining conformance to the dimensional tolerances, a measured value is not rounded off. To determine applicable limits when a dimension is specified to more decima
35、l 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 Determine Conformance with Specifications.American National Standard Dimensional Tolerances for Aluminum Mill P
