ANSI H American National Standard Dimensional Tolerances for Aluminum Mill Products. This Standard is a revision of ANSI H(M), which consists of logical values for long-term metric use rather than a restatement of ANSI.

Whena dimension tolerance is specifiedother than asan equal bilateral tolerance, the value of the standard tolerance is that which applies to the mean of the maximum and minimum dimensions permissible under the tolerance for the dimension under consideration.
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. TolerancesforT,T,T,l,TandT tempers shall be as agreed upon between the b35.2 and vendor and at the time the contract or order is entered.
When weight of piece on flat surface minimizes deviation. O Some papers may require a greater tolerance.
Note that the Col. From this measurement, the actual deviation from straightness of the bar at that point is subtracted. They are the basis of the dimensional tolerances specified in U. Conditioning allowance is an additional tolerance at localized areas to permit removal of possible surface conditions. Twist is normally measured by placing the bar on a flat surface and at any point along its length measuring the maximum distance between the bottom surface of the bar and the flat surface.
O81 Up thru 0. This latest revision consists of an expandedrange of specified diameters for round wire, rod and drawing stock, clarification of the 5xxx alloys with ajsi extrusion tolerances and editorial corrections. Minimum weight iscontrolled by tolerances for outside diameter and wall thickness.
In addition, tolerances have been developed for products not covered initially, and the data have been extended to embrace the larger sizes now being produced. Moreover, no person ansu have the right or authorityto issue an interpretation of an American National Standard in the name of the American National Standards Institute.
Not applicable to Allowable deviation from specified contour: Example-Alloy hollow profile having 1 x 3 rectangularoutside dimensions;width tolerance is Io. The circumscribing circle diameter is the diameter of the smallest circle that will completely enclose the cross section of the extruded product.
Structured Profiles Tolerance limits for aluminum alloy structural profiles are identical with those for other extruded profiles as shown in Section Differencebetween radius A and specified radius Sharp corners 0.
Tolerances for extruded profiles in T, T, T, T, O and TE51O tempers shall be as agreed upon between purchaser and vendor at the time the contract or order is entered. When a dimension tolerance is specified other than as equal bilateral tolerance, the value of the standard tolerance is that which applies to the mean of the maximum and minimum dimension permissible under the tolerance for the dimension under consideration. Tolerance, degrees Maximum allowable linear deviation inch per inch of width.
Tube and Pipe – Tables Successive editions of the “Standards for Aluminum Mill Products” have been revised to include new anis and to keep the manual abreast of industry advances. O1O x Measured length, it.
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. O10x Measured length, ft.

The Amencan National Standards Anso does not develop standards and will under no circumstances give an interpretation of any American Standard.
The n35.2 completed its work later inand the Association issued the first edition of its Drafting Standards for Extruded and Tubular Products, including the tolerances, in October of that year. Locate distance “8” in column 1. Tread Sheet and Plate – Tables 7.
