The Amencan National Standards Institute does not develop standards and will under no circumstances give an interpretation of any American Standard. Tread Sheet and Plate – Tables 7. The following values are used to convert angular tolerances to linear deviation: Applies only in a lengths 20 ft. Allowable deviation from nominal angle: The mean wall anai of other-thanround tube is the average of j35.2 measurements taken opposite each other at approximate center line of tube and perpendicular to the longitudinal axis of the cross section.

### ANSI H | The Aluminum Association

Place the bar or rod on a level surface so h335.2 the departure from straightness is horizontal. This latest revision consists of an expandedrange of specified diameters for round wire, rod and drawing stock, clarification of the 5xxx alloys with special extrusion tolerances and editorial corrections. Distances ‘C” are shown merely to indicate incorrect values for determining which of columns ‘B’ Tolerances applicable h5.2 dimensions ‘ X are determined as follows: Up thru 1 Over 1 In any 1 in.

In Europe, foil is equal to and less than 0.

Covering area in sq. T, T, T, T, and l O04,,,Difference between AA and specified length Col. When a dimension tolerance is specifiedother ani 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 consideration.

O98, I 31 or Greater I I h3.52 l k–A.

## ANSI H35.2

Not applicable to the weld area or to embossed tube. O50 x Measured length, fl.

Foil-A rolled product rectangular in cross section of thickness less than 0. To determine applicable limits when a dimension is specified to more decimal places than are used in these standards, it shall be rounded off to the same number of places in conformance with ASTM E29, StandardPractice for Using SignificantDigits in Test Data to Determine Conformance with Specifications.

O50x Measured length, ft. When a dimension tolerance is specified other than asan 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.

I70,, – -This Amencan National Standard may be revised or withdrawn at any time. TX51 is a general designation for the following stress-relievedtempers: Note that the Col. Section Intentionally Blank 6. Conditions include die lines and handling marks. For all numbered footnotes,see two precedingpages. D 2 Blended Comers Up thru 0.

Not applicable to annealed O temper tube.

I20,,-The width tolerance of 1 x 3 inch rectangular tube is plus and minus 0. Maximum allowable linear deviation inch per inch of width 0.

Consensus requires j35.2 all views and objections be considered, and that a concerted effort be made toward their resolution. Brazing Sheet-Sheet of a brazing alloy, or sheet clad with a brazing alloy on one or both sides. Tube-A hollow g35.2 product that is long in relation 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.

To convert the standard twist tolerance degrees to an equivalent ani value, the sine of the standard tolerance is multiplied by the width of the surface of the section that is on the flat surface. Forging Stock – Tables K x Measured length, it.

Thickness tolerance per Table From this measurement, the actual deviation from straightness of the welded tube at that point is subtracted.
