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.

From this measurement, the actual deviation from ans of the extruded section at that point is subtracted. Maximum allowable linear deviation inch per inch of width 0. O04 x W inches. Conditions include die lines, mandrel lines and handling marks. Electrical Conductors – Tables Not applicable to the weld area or to embossed tube.

Place the bar or rod on a level surface so that the departure from straightness is horizontal. TolerancesnotapplicabletoTX,orTX tempertubehavingawall thickness less than 0. When both outside and inside diameters or inside diameter and wall thickness are specified, the tolerance applicable to the specified or calculated O.
Tolerance, degrees Maximum allowable linear deviation inch per inch of width. Specified Wall Thickness in. Distances ‘C” are shown merely to indicate incorrect values for determining which of wnsi ‘B’ Tolerances applicable to dimensions ‘ X are determined as follows: 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.
Where instruments permitting the required degree of accuracy amsi are used, the tolerances are expressed in decimals as follows except for foil: For schedule 5 and IO, only diameter, wall thickness and length tolerances apply.
The following values are used to convert angular tolerances to linear deviation: Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. W x Measured length, ft.
The camber of a pattern line is the maximum distance between the center of any figure in a pattern line and a line 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. 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 Minimum ansl is controlled by tolerances for outside diameter and wall thickness.
Ansj Committee H35 was transferred to an Accredited Standards Committee on December 28,and this revision was developed under the Accredited Standards Committee method.
When the area between the surface fotming an angle is ail metal, vaiues in column 2 apply if the larger surface length to metal thickness ratio is 1 or less. O06, At least three such measurements are made, one near each end and one near the middle of the coil. Not applicable to annealed O temper pipe.
Twist is normally measured by placing the welded tube on a flat surface and at any point along its length measuringthe maximum distance between the bottom surface of the welded tube and the flat surface.
Determinewhich of columns is applicable, dependent on distance “A. Thickness tolerance per Table D 2 Blended Comers Up thru 0.
By ,the Association’s technical activitieshad grown to the point that a standingTechnical Committeewas needed. Ahsi is normally measured by placing the drawn tube on a flat surface and at any point along its lengthmeasuring the maximum distance between the bottom surface of the drawn tube and the flat surface. Tolerances applicable at ambient mill temperatures.
Structural Profile-A profile ansk or extruded, in certain standard alloys, tempers, sizes, and sections, such as angles, channels, tees, zees, I-beams, and H-sections, commonly used for structural purposes. Example-Alloy hollow profile having 1 x 3 rectangularoutside dimensions;width tolerance is Io. I 1 1, Wire-A solid wrought product that is long in relation to its cross section, which is square or rectangular with sharp or rounded comers or edges, or is round, hexagonal, or octagonal, and whose diameter or greatest perpendicular distance between parallel faces is less than 0.
The mean wall thickness of other-thanround tube ansk 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. The width tolerance of 1 x 3 inch rectangular tube is plus and minus 0.
They represent the maximum deviation from specified dimensions that may be expected in any individual piece. Straightness shall be measured by placing the bar on a level table so that the arc or departure from straightness is horizontal.
Straightnessmust be met in all orientations, including orientations which are not self-supporting. Not applicableto alloy tube. Shaded tolerancesdenote products with a circumscribing circle size of 10 snsi in diameter and over. Minimum weight iscontrolled by tolerances annsi outside diameter and wall thickness. Xnsi,,-Welded Tube-A tube produced by forming and seamwelding sheet longitudinally.
