This work was completed later inand the resulting data were published in the first edition of the Association’s “Standards for Aluminum Mill Products” in June Distances ‘C” are shown merely to indicate incorrect values for determining which of columns ‘B’ Tolerances applicable to dimensions ‘ X are determined as follows: Successive editions of the “Standards for Aluminum Mill Products” have been revised to include new data and to keep the manual abreast of industry advances.
Not applicable to Allowable deviation from specified contour: T, T, T, and l O01 1 1. Up thru 1 Over 1 In any 1 in. Not applicableto alloy tube.

O See Tables 7. Hand Forgings – Table They are the basis of the dimensional tolerances specified in U. 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 aansi. 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.
Tread Platesheet or plate having a raised figured pattern on one surface to provide improved traction.
ansii Tube-A hollow wrought product that is long in ans to its cross section, which is symmetrical and is round, a regular hexagon or octagon, elliptical, or square or rectangular with sharp or rounded comers, and that has uniform wall thickness except as affected by corner radii.
I 31 or Greater I I l l k–A. 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.
Not applicable to O temper tube.
O As measured with a contour gauge whose surface is limitedto a maximum subtended angle of 90 degrees. O50 The tolerance for the width is the value in Col.
O1O x Measured length, it. 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.
W x Measured length, ft. When a dimension tolerance is specifiedother than as an 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 ahsi.
Other types are subject to special inquiry. The Olsen Cup and similar tests frequently used as measures of formability are not sufficiently reproducible to permit the establishment of standards for acceptance or rejection of material. When both outcide anwi inside diameters or inside diameter and wall thickness are specified, the tolerance applicable to the specified or calculated O.
I20,znsi,-Ansj, Rod, Bar and Profiles – Extruded 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 D 2 Blended Comers Up thru 0. Structured Profiles Tolerance limits for aluminum alloy structural profiles are identical with those for other extruded profiles as shown in Section Standard Limits for Expressing Tolerances 2.
This Amencan National Standard may be revised or withdrawn at any time. Structural Profile-A profile rolled 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.
Substantial agreement means much more than a simple majority, but not necessarily unanimity. TX and TX are general designations for the following stressrelieved tempers: O04 x W inches.
