A
These tolerances are applicable to the average profile. Wider tolerances may be required for some profiles and closer tolerances may be possible for others.
B
The tolerances applicable to a dimension composed of two or more component dimensions is the sum of the tolerances of the component dimensions if all of the
component dimensions are indicated.
C
When a tolerance is specified other than as an equal bilateral tolerance, the value of the standard tolerance is that which would apply to the mean of the maximum
dimensions permissible under the tolerance.
D
These tolerances do not apply to space dimensions such as dimensions X and Z of the example even when Y is 75 % or more of X. For the tolerance applicable to
dimensions X, use Col. 4, 5, 6, 7, 8 or 9, dependent on distance A and the circumscribing circle diameter.
E
At points less than 0.250 in. from base of leg the tolerances in Column 2 are applicable.
B107/B107M−13 (2021)
F
The following tolerances apply where the space is completely enclosed (hollow profiles): For the width (A) the tolerance is the value shown in Column 4 for the depth
(D), the tolerance is the value shown in Column 4 for the width (A). In no case is the tolerance for either width or depth less than at the corners (Column 2, metal
dimensions).
Example—Hollow profile having 1 by 3 in. rectangular outside dimensions and having a circumscribing circle diameter less than 10 in.: width tolerance is± 0.024 in. and
depth tolerance ±0.034 in. (Tolerances at corners, Column 2, metal dimensions, are ±0.024 in. for the width and ±0.012 in. for the depth.)
G
Where dimensions specified are outside and inside, rather than wall thickness itself, the allowable deviation (eccentricity) given in Column 3 applies to mean wall
thickness (mean wall thickness is the average of two wall thickness measurements taken at opposite sides of the void).
H
In the case of Class 1 Hollow Profiles the standard wall thickness tolerance for extruded round tube is applicable. (A Class 1 Hollow Profile is one whose void is round
and 1 in. or more in diameter and whose weight is equally distributed on opposite sides of two or more equally spaced axes.)
I
Tolerance applicable to the wall thickness enclosing the void of hollow and semihollow profiles is subject to negotiation when the nominal thickness of one wall is three
times or greater than that of the opposite wall.

A
These tolerances are applicable to the average profile. Wider tolerances may be required for some profiles and closer tolerances may be possible for others.
B
The tolerances applicable to a dimension composed of two or more component dimensions is the sum of the tolerances of the component dimensions if all of the
component dimensions are indicated.
C
When a tolerance is specified other than as an equal bilateral tolerance, the value of the standard tolerance is that which would apply to the mean of the maximum
dimensions permissible under the tolerance.
D
These tolerances do not apply to space dimensions such as dimensions X and Z of the example even when Y is 75 % or more of X. For the tolerance applicable to
dimensions X, use columns 4, 5, 6, 7, 8 or 9, dependent on distance A and the circumscribing circle diameter.
E
At points less than 6.30 mm in from base of leg the tolerances in Column 2 are applicable.
B107/B107M−13 (2021)
F
The following tolerances apply where the space is completely enclosed (hollow profiles): For the width (A) the tolerance is the value shown in Column 4 for the depth
(D). For the depth (D), the tolerance is the value shown in Column 4 for the width (A). In no case is the tolerance for either width or depth less than at the corners (Column
2, metal dimensions).
Example—Hollow profile having 25 mm by 75 mm rectangular outside dimensions and having a circumscribing circle diameter less than 250 mm: width tolerance is ±0.60
mm and depth tolerance ±1 mm. Tolerances at corners, Column 2, metal dimensions, are ±0.60 mm for the width and ±0.25 mm for the depth.)
G
Where dimensions specified are outside and inside, rather than wall thickness itself, the allowable deviation (eccentricity) given in Column 3 applies to mean wall
thickness (mean wall thickness is the average of two wall thickness measurements taken at opposite sides of the void).
H
In the case of Class 1 Hollow Profiles the standard wall thickness tolerance for extruded round tube is applicable. (A Class 1 Hollow Profile is one whose void is round
and 25 mm or more in diameter and whose weight is equally distributed on opposite sides of two or more equally spaced axes.)
I
Tolerance applicable to the wall thickness enclosing the void of hollow and semihollow profiles is subject to negotiation when the nominal thickness of one wall is three
times or greater than that of the opposite wall.
