Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 6362-4 was prepared by Technical Committee ISO/TC 79, Light metals and their alloys, Subcommittee
SC 6, Wrought aluminium and aluminium alloys.
This second edition cancels and replaces the first edition (ISO 6362-4:1988), which has been technically revised.
ISO 6362 consists of the following parts, under the general title Wrought aluminium and aluminium alloys —
Extruded rods/bars, tubes and profiles:
— Part 1: Technical conditions for inspection and delivery
— Part 2: Mechanical properties
— Part 3: Extruded rectangular bars — Tolerances on shape and dimensions
— Part 4: Profiles — Tolerances on shape and dimensions

NOTE 1 Dimensional tolerances for the space portions of hollow parts shall be as given in Table 5 (column D).
NOTE 2 When either only a minus or plus side tolerance is specified, the value in this table shall be doubled.
a
The circumscribing circle is the smallest circle which encloses entirely the cross-section of the shape. However, this dimension may have to be increased when shapes are subjected to corrections of the uneven
thickness or in the case of hollow shapes for which the centre of the circumscribing circle needs to be considered, based on the void. These matters should be confirmed with the supplier beforehand as required.
b
When the dimensional tolerance is not made equal at the plus side and minus side, determine the value in the column corresponding to the centre of allowable range, and use this value as a standard to decide the
tolerance.
c
In the case of angled shapes as shown in Figure 3, the tolerances shall be decided not on the base of the length of dimension X, but on the base of the angle α (see 6.6).
d
Even when value Y in Figure 3 is equal to or greater than 75 % of value X, these tolerances are not applied to the dimension X or Z. The tolerances for X and Y shall conform to the column corresponding to space
dimension C and C depending on the distance from the reference base.
i e
e
If the purchaser and the supplier agree, the outside dimension C may be specified instead of the inside dimension C .
e i
f 2
This is applicable when the space volume enveloped with hollow part is 70 mm² or larger. If less than 70 mm , employ column A.
g
If 5 mm or under, employ column A.
