American National Standard Dimensional Tolerances for Aluminum Mill Products

American National Standard Approval of an American National Standard requires verification by 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 agreement has been reached by directly and materially affected interests. Substantial agreement means much more 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 anyone, whether he has approved the standards or not, from manufacturing, 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 any 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 title page of this standard. CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. 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. Purchasers of American National Standards may receive current information on all standards by calling or writing the American National Standards Institute, 25 West 43rd Street, New York, NY 10036. --```,,,,,,,`,````,,,`,,```````,-`-`,,`,,`,`,,`---

ANSI H35.2(M)–2009

Foreword

--```,,,,,,,`,````,,,`,,```````,-`-`,,`,,`,`,,`---

This Standard is a revision of ANSI H35.2(M)-2006, which consists of logical values for long-term metric use rather than a restatement of ANSI H35.2 in metric . This revision consists of modified foil and sheet definitions.



ANSI H35.2(M)–2009

American National Standard Dimensional Tolerances for Aluminum Mill Products 1. Definitions

Alclad One Side Sheet) a metallurgically bonded aluminum or aluminum alloy coating that is anodic to the core, thus electrolytically protecting the core against corrosion.

Bar—A 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 over 10 mm.

Brazing Sheet—Sheet of a brazing alloy, or sheet clad with a brazing alloy on one or both sides. Duct Sheet—Coiled or flat sheet in specific tempers, widths and thicknesses, suitable for duct applications.

Fin Stock—Coiled sheet or foil in specific alloys, tempers, and thickness ranges suitable for manufacture of fins for heat-exchanger applications.

Tube—A hollow wrought product 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.

Foil—Generally, a rolled product rectangular in cross section of thickness 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.

Heat-Exchanger—Tube ube for use in apparatus 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.)

Forging Stock—A wrought or cast rod, bar or other section suitable for forging.

Welded Tube—A tube produced by forming and seamwelding sheet longitudinally.

Pipe—Tube in standardized combinations of outside diameter and wall thickness, commonly designated by “Nominal Pipe Sizes” and “ANSI Schedule Numbers.” (Note: Larger sizes usually greater than 25 millimetres are typically extruded while smaller sizes are typically drawn.)

Wire—A 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.

Plate—A rolled product that is rectangular in cross section and with thickness over 6.3 millimetres and with sheared or sawed edges.

2. Standard Limits for Expressing Tolerances

Tread Plate—Sheet or plate having a raised figured pattern on one surface to provide improved traction.

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 decimals as follows (except for foil):

Profile—A 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. Structural Profile—A profile in certain standard alloys, tempers, sizes, and sections, such as angles, channels, tees, zees, I-beams, and H-sections, commonly used for structural purposes. For channels and I-beams there are two standards, namely Aluminum Association Standard and American Standard.

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

Rod—A solid wrought product over 10 mm in diameter that is long in relation to cross section and over 10 millimetres in diameter.

For measurements commonly made with instruments not permitting such accuracy, standard dimensional tolerances are expressed as follows:

Shape—This term is no longer recommended. The term “Profile” is preferred. See “Profile.”

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

--```,,,,,,,`,````,,,`,,```````,-`-`,,`,,`,`,,`--

Sheet—Generally, 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 and sheet. Sheet products in this gage range are supplied to sheet product specifications.

2.2 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 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 Determine Conformance with Specifications.

Alclad Sheet—Composite sheet comprised of an aluminum alloy core having on both surfaces (if one side only,

Q For TX51 tempers, tolerance is applicable only to thicknesses of 12.50 mm and over. W TX51 is a general designation for the following stress-relieved tempers: T351, T451, T651, T851, and T7351. E When weight of piece on flat surface minimizes deviation. R Twist is normally measured by placing the product on a flat surface and at any point along its length measuring the maximum distance between the bottom surface of the section and the flat surface. From this measurement, the actual deviation from straightness of the section at that point is subtracted. The remainder is the twist. To convert the standard twist tolerance (degrees) to an equivalent linear value, the sine of the standard tolerance is multiplied by the width of the surface of the section that is on the flat surface. The following values are used to convert angular tolerance to linear deviation:

R Where dimensions specified are outside and inside, rather than wall thickness itself, the allowable deviation (eccentricity) given in Column 3 applies to mean wall thickness. (Mean wall thickness is the average of two wall thickness measurements taken at opposite sides of the void.)

Footnotes for Tables 11.2 through 11.4

Q These Standard and Precision Tolerances are applicable to the average profile. The extrusion conditions required to produce the wide variety of alloy-temper and profile combinations require close review between customer and producer to determine critical characteristics and tolerance capability. Aggressive profile characteristics may require wider than standard tolerance and closer than precision tolerance may be feasible for other characteristics. W The tolerance applicable to a dimension composed of two or more component dimensions is the sum of the tolerances of the component dimensions if all of the component dimensions are indicated.

Examples Illustrating Use of Table 11.2, Page 11-6 Closed-Space Dimensions

All dimensions designated “Y” are classed as “metal dimensions,” and tolerances are determined from column 2. Dimensions designated “X” are classed as “space dimensions through an enclosed void,” and the tolerances applicable are determined from column 4 unless 75 percent or more of the dimension is metal, in which case column 2 applies.

Tolerances applicable to dimensions “X” are determined as follows: 1. Locate dimension “X” in column 1. 2. Determine which of columns 4–9 is applicable, dependent on distance “A.” 3. Locate proper tolerance in column 4, 5, 6, 7, 8 or 9 in the same line as dimension “X.” Dimensions “Y” are “metal dimensions”; tolerances are determined from column 2. Distances “C” are shown merely to indicate incorrect values for determining which of columns 4–9 apply.

Tolerances applicable to dimensions “X” are not determined from Table 11.2; tolerances are determined by standard tolerances applicable to angles “A.”

Tolerances applicable to dimensions “X” are determined as follows: 1. Locate distance “B” in column 1. 2. Determine which of columns 4–9 is applicable, dependent on distance “A.” 3. Locate proper tolerance in column 4, 5, 6, 7, 8 or 9 in the same line as value chosen in column 1.

Footnotes for Tables 11.2 through 11.4 (Continued) T In the case of Class 1 Hollow Profiles the standard wall thickness tolerance for extruded round tube is applicable. (A Class 1 Hollow Profile is one whose void is round and one inch or more in diameter and whose weight is equally distributed on opposite sides of two or more equally spaced axes.) Y At points 5 mm and less from base of leg the tolerances in Col. 2 are applicable. U Tolerances for extruded profiles in T3510, T4510, T6510, T73510, T76510 and T8510 tempers shall be as agreed upon between purchaser and vendor at the time the contract or order is entered. I The following tolerances apply where the space is completely enclosed (hollow profiles); For the width (A), the balance is the value shown in Col. 4 for the depth dimension (D). For the depth (D), the tolerance is the value shown in Col. 4 for the width dimension (A). In no case is the tolerance for either width or depth less than the metal dimensions (Col. 2) at the corners. Example—Alloy 6061 hollow profile having 25 ⋅ 75 mm rectangular outside dimensions; width tolerance is ±0.46 mm and depth tolerance ±0.86 mm. (Tolerances at corners, Col. 2, metal dimensions, are ±0.60 mm for the width and ±0.25 mm for the depth.) Note that the Col. 4 tolerance of 0.46 mm must be adjusted to 0.60 mm so that it is not less than the Col. 2 tolerance. Copyright The Aluminum Association Inc. Provided by IHS under license with AA No reproduction or networking permitted without license from IHS

O These tolerances do not apply to space dimensions such as dimensions “X” and “Z” of the example (right), even when “Y” is 75 percent or more of “X.” For the tolerance applicable to dimensions “X” and “Z,” use Col. 4, 5, 6, 7, 8 or 9, dependent on distance “A.”

P The wall thickness tolerance for hollow or semihollow profiles shall be as agreed upon between purchaser and vendor at the time the contract or order is entered when the nominal thickness of one wall is three times or greater than that of the opposite wall. { 5xxx alloys tolerances are 150% of all other alloys, standard tolerance.

Footnotes for Tables 11.5 through 11.8 Q These Standard Tolerances are applicable to the average profile; wider tolerances may be required for some profiles, and closer tolerances may be possible for others. W TX510 and TX511 are general designations for the following stress relieved tempers: T3510, T4510, T61510, T6510, T8510, T73510, T76510 and T3511, T4511, T61511, T6511, T8511, T73511, T76511, respectively. E When weight of piece on the flat surface minimizes deviation. R The circumscribing circle diameter is the diameter of the smallest circle that will completely enclose the cross section of the extruded product. T Tolerances for T3510, T4510, T6510, T73510, T76510, and T8510 tempers shall be as agreed upon between purchaser and vendor at the time the contract or order is entered. Y Twist is normally measured by placing the product on a flat surface and at any point along its length measuring the maximum distance between the bottom surface of the section and the flat surface. From this measurement, the actual deviation from straightness of the section at that point is subtracted. The remainder is the twist. To convert the standard twist tolerance (degrees) to an equivalent linear value, the sine of the standard tolerance is multiplied by the width of the surface of the section that is on the flat surface. The following values are used to convert angular tolerance to linear deviation:

U Applies only if the thickness along at least 1/3 of the total perimeter is 2.50 mm or less. Otherwise use the tolerance shown for 2.50 mm and over. I Tolerance for “O” temper material is four times the standard tolerances shown. O Straightness must be met in all orientations, including orientations which are not self ing.

ANSI H35.2(M)–2009 Dimensional Tolerances for T Angles are measured with protractors or with gages. As illustrated, a four-point system is used, two points being as close to the angle vertex as practical, and the others near the ends of the respective surfaces forming the angle. Between these points of measurement surface flatness is the controlling tolerance. Y When the area between the surface forming an angle is all metal, values in column 2 apply if the larger surface length to metal thickness ratio is 1 or less. U When two legs are involved the one having the larger ratio determines the applicable column. I Not applicable to 2219 alloy extrusions. Most profiles in 2219 alloy will have die lines about twice the depth shown in the table; however, for each profile the supplier should be ed for the roughness value to apply. O If unspecified, the radius shall be 1 mm maximum including tolerances. P Tolerance for “O” temper material is four times the standard tolerances shown.

Q These Standard Tolerances are applicable to the average profile; wider tolerances may be required for some profiles, and closer tolerances may be possible for others. W Conditions include die lines and handling marks. E As measured with a contour gage whose surface is limited to a maximum subtended angle of 90 degrees. Extruded curved surfaces comprising more than a 90-degree subtended angle are checked by sliding the gage across the surface, thus checking two or more 90-degree portions of the surface. Extruded profile surfaces comprising arcs formed by two or more radii require the use of a separate contour gage for each portion of the surface formed by an individual radius. R Tolerances for T3510, T4510, T6510, T73510, T76510 and T8510 tempers shall be as agreed upon between the purchaser and vendor and at the time the contract or order is entered.

TABLE 12.12 Angularity—Extruded Tube Allowable deviation from square: ±2 degrees.

Footnotes for Tables 12.2 through 12.14 { Twist is normally measured by placing the product on a flat surface and at any point along its length measuring the maximum distance between the bottom surface of the section and the flat surface. From this measurement, the actual deviation from straightness of the section at that point is subtracted. The remainder is the twist. To convert the standard twist tolerance (degrees) to an equivalent linear value, the sine of the standard tolerance is multiplied by the width of the surface of the section that is on the flat surface. The following values are used to convert angular tolerance to linear deviation: Tolerance Max. Allowable Linear Degrees Deviation mm/mm of Width

Q When outside diameter, inside diameter, and wall thickness (or their equivalent dimensions in other than round tube) are all specified, standard tolerances are applicable to any two of these dimensions, but not to all three. When both outside and inside diameters or inside diameter and wall thickness are specified, the tolerance applicable to the specified or calculated O.D. dimension shall also apply to the I.D. dimension. W When a dimension tolerance is specified other than as an equal bilateral tolerance, the value of the standard tolerance is that which applied to the mean of the maximum and minimum dimensions permissible under the tolerance for the dimension under consideration. E Mean diameter is the average of two diameter measurements taken at right angles to each other at any point along the length. R Not applicable in the annealed (O) temper of if wall thickness is less than 2.5 percent of outside diameter of a circle having a circumference equal to the perimeter of the tube. T The mean wall thickness of round tube is the average of two measurements taken opposite each other. The mean wall thickness of other-thanround tube is the average of two measurements taken opposite each other at approximate center line of tube and perpendicular to the longitudinal axis of the cross section. Y When dimensions specified are outside and inside, rather than wall thickness itself, allowable deviation at any point (eccentricity) applies to mean wall thickness. U Tolerances for O, T3510, T4510, T6510, T73510, T76510 and T8510 tempers shall be as agreed upon between purchaser and vendor at the time the contract or order is entered.

Footnotes for Tables 12.44 Through 12.47 Q Tolerance is applicable when weight of tube on flat surface minimizes deviation. W Twist is normally measured by placing the product on a flat surface and at any point along its length measuring the maximum distance between the bottom surface of the section and the flat surface. From this measurement, the actual deviation from straightness of the section at that point is subtracted. The remainder is the twist. To convert the standard twist tolerance (degrees) to an equivalent linear value, the sine of the standard tolerance is multiplied by the width of the surface of the section that is on the flat surface. The following values are used to convert angular tolerance to linear deviation: Tolerance Degrees

Q Twist is normally measured by placing the product on a flat surface and at any point along its length measuring the maximum distance between the bottom surface of the section and the flat surface. From this measurement, the actual deviation from straightness of the section at that point is subtracted. The remainder is the twist. To convert the standard twist tolerance (degrees) to an equivalent linear value, the sine of the standard tolerance is multiplied by the width of the surface of the section that is on the flat surface. The following values are used to convert angular tolerance to linear deviation:

W When mass of bar on flat surface minimizes deviation.

Q Deviation from straightness shall be checked as follows: Place the bar or rod on a level surface so that the departure from straightness is horizontal. Measure the maximum depth of arc to the nearest 0.8 mm using a steel scale and a 3-metre long straightedge. W When mass of bar on flat surface minimizes deviation. E Twist is normally measured by placing the product on a flat surface and at any point along its length measuring the maximum distance between the bottom surface of the section and the flat surface.
