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.

Equivalent round diameter is the diameter of the circle having a circumference equal to the perimeter of the tube. Locate distance “8” in column 1.
Not applicable to alloy exbusions. Alclad Sheet-Composite sheet comprised of an aluminum h35.2 core having on both surfaces if on one side only, Alclad One Side Sheet a metallurgically bonded aluminumor aluminum alloy coatingthat is anodic to the core, thus electrolyticallyprotecting the core against corrosion.
Not applicable to Allowable deviation from specified contour: Other types are subject to special inquiry. O30 than-round tube is the average of two measurementstaken opposite each other at approximate center line of tube and perpendicular to the longitudinal axis of the cross section. The following values are used to convert angular tolerances to linear deviation: Straightness shall be measured by placing the bar on a level table so that the arc or departure from straightness is horizontal.
Ve in any 1O ft. Most profiles in alloy will have die lines about twice the depth absi in the table; xnsi, for each profilethe supplier should be contacted for the roughnessvalue to apply. 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 bottomsurface of the bar and the flat surface. L a Y Tolerances aDplicable to dimensions ‘X” are determined asfoiiows: O1O x Measured length, it.
For the y35.2 Dthe tolerance is the value shown in Col. Based on nominaldimensions, plain ends, b35.2 a density of 0. Tolerances applicable at ambient mill temperatures. Tolerance, degrees Maximum allowable linear deviation inch per inch of width 0. I70 aansi,,- -One ofthe committee’s assignmentswas to develop standardtolerances for aluminum extrusions.
O10 x Measured length, ft. For most pieces the deviation from specified dimensions will be less than the tolerance shown. O04,Not applicable to the weld area or to embossed tube. Difference between AA a n d specified diameter 0. When dimensions specified are outside and inside, rather than wall thickness itself, allowable deviation at any point eccentricity is plus and minus 10 percent of the mean wall thickness but not less than Electrical Conductors – Tables A change h35.
dimension of 0. TolerancesforT,T,T,l,TandT tempers shall be as agreed upon between the purchaser and vendor and at the time the contract or order is entered. This Amencan National Standard may be revised or withdrawn at any time. Conditions include die lines, mandrel lines and handling marks. 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 anai of the maximum and minimum dimensions permissible under the tolerance for the dimension under consideration.

Specified bar thickness 0. Wire, Rod, Bar and Profiles – Extruded Allowable deviation from specified length: Wire, Rod, and Bar-? When weight of pipe on flat surface minimizes deviation. Over 12 thru 30 0 In Europe, foil is equal to and less than 0. In no case is the tolerance for anis width or depth less than the metal dimensions Col.
The allowed deviationfrom nominal weight shall not exceed plus 8 percent. O06, H x Measured length, ft. Thewidthtoleranceof b35.2 1 x 3 inch alloy rectangular tube is Io. O75 O Specified thickness does not include height of pattern. Minimum weight iscontrolled by tolerances for outside diameter and wall thickness. Cup test values, when used, are acceptable only as general guidelines for rating comparative formability.
Section Intentionally Blank 6. O See Tables 7.
The camber of a pattern line is the maximum distance between the center of any figure in a pattern line and a y35.2 parallel with the edge of the plate that passes through the center of the figure in the same pattern line nearest to the edge of the floor plate.
Alloy Includes Alclads Specified Thickness in. The committee completed its work later inand the Association issued the first edition of its Drafting Standards for Extruded and N35.2 Products, including the tolerances, in October of that year.
The width tolerance of 1 x 3 inch rectangular tube is plus and minus 0.
