Shaded tolerancesdenote products with a circumscribing circle size of 10 inches in diameter and over. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved aansi standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards.

O21 EE 54. The remainder is the twist. IO2, To convert the standard twist tolerance degrees to anssi 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.
One ofthe committee’s assignmentswas to develop standardtolerances for aluminum extrusions. For most pieces the deviation from specified dimensions will be less than the tolerance shown. Foil-A rolled product rectangular in cross section of thickness less than 0. O98, Not applicable to annealed O temper pipe. I 31 or Greater I I l l k–A. Not applicable to alloy exbusions. Alloy Includes Alclads Specified Thickness in.
Welded Tube-A tube produced by forming and seamwelding sheet longitudinally. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution.
TX51 is a general designation for the following stress-relievedtempers: The committee 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. Capabilityto provide tighter tolerances may vary j35.2 supplier. O75,Twist is normally measured by placing the extruded section on a flat h35.2 at any point along its length measuring the maximum distance between the bottom surface of the extruded section and the flat surface.
Tolerances applicable to dimensions “X” are not determined from Table Ve in any 1O ft. T, T, T, and l Locate proper tolerance in column 4,5,6, 7, 8 or 9 in the same line as dimension “X.
Rod-A solid wrought product that is long in relation to its circular ansj section, which is not less than 0.
O81 Up andi 0. Copyright The Aluminum Association Inc. Wire, Rod, and Bar-? O50 x Measured length, ft. Allowable deviation from specified length: The followingvalues are used to convert angular tolerances to linear deviation: When a dimension tolerance is specified other than as ansu 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.
O10 x Measured length, ft.
When a dimension tolerance is specified other 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 ajsi the tolerance of the dimension under wnsi.
Equivalent round diameter is the diameter of a circle having a circumference equal to the perimeter of the tube. 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. A change in dimension of 0. Tolerance is applicable when weight of tube on flat surface minimizes deviation.
Extruded Coiled Tube – Tables 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. Shaded tolerances denote products with a circumscribing circle size of 10 inches in diameter and over.
Allowable deviation from nominal depth of corrugation: O1O x Measured length, it. Mean wall thickness is the average of two wall thickness measurements taken at znsi sides of the void.
Note that the Col. Requests for interpretation should be addressedto the secretariator h335.2 name appears on the title page of this standard. Moreover, no person shall have the right or authorityto issue an interpretation of an American National Standard in the name of the American National Standards Institute.
Otherwise use the tolerance shown for 0.
TolerancesnotapplicabletoTX,orTX tempertubehavingawall thickness less than 0. They are the basis of the dimensional tolerances specified in U. Tolerance per Table From this measurement, the actual deviation from straightness of the extruded section at that point is subtracted.
Electrical Conductors – Tables Not applicableto alloy tube. O As measured with a contour gauge whose surface is limitedto a maximum subtended angle of 90 degrees.
