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 6362-1 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 6362-1:1986), 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
— Part 5: Round, square and hexagonal bars — Tolerances on shape and dimensions

— Part 6: Round, square, rectangular and hexagonal tubes — Tolerances on shape and dimensions

— Part 7: Chemical composition

3  Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
rod/bar

solid wrought product of uniform cross-section along its whole length, supplied in straight lengths

NOTE 1 Rod is normally less than 6 mm in diameter or minor dimension.

NOTE 2 In North America, the minimum diameter of a rod is 9,525 mm (0,375 in). Below this limit the product is called wire.

NOTE 3 The cross-sections are in the shape of circles, squares, rectangles or regular hexagons. Products with a

square, rectangular or hexagonal cross-section may have corners rounded along their whole length.

NOTE 4 For rectangular bars, the thickness exceeds one-tenth of the width. The term “rectangular bar” includes

“flattened circles” and “modified rectangles”, of which two opposite sides are convex arcs, the other two sides being

straight, of equal length and parallel.
3.2
tube

hollow wrought product of uniform cross-section with only one enclosed void along its whole length, and with

a uniform wall thickness, supplied in straight lengths or in coiled form, provided the inner and outer cross-

sections are concentric and have the same form and orientation

NOTE The cross-sections are in the shape of circles, squares, rectangles or regular hexagons. Hollow products with

square, rectangular or regular hexagonal cross-sections may have corners rounded along their whole length.

3.3
profile

wrought product of uniform cross-section along its whole length, with a cross-section other than rod/bar, tube,

sheet or strip, supplied in straight lengths or in coiled form and where the product is long in relation to its cross-

sectional dimensions
NOTE According to the form of its cross-section, it is called:

a) hollow profile: the cross-section includes either one enclosed void, provided that the cross-section is other than tube,

or more than one enclosed void;
b) solid profile: the cross-section does not include any enclosed void.
3.4
inspection lot

consignment, or a part thereof, submitted for inspection, comprising products of the same grade or alloy, form,

temper, size, shape, thickness or cross-section and processed in the same manner

3.5
heat-treatment batch or lot

quantity of products with an identical set of criteria, e.g. grade or alloy, form, thickness or cross-section

and produced in the same way, heat-treated in one furnace load, or such products so solution-treated and

subsequently precipitation-treated in one furnace load
NOTE 1 More than one solution-treatment lot may be included in a furnace load.

NOTE 2 For the heat-treatment in a continuous furnace, the products heat-treated during a period of time less than 8 h

may be considered as belonging to the same heat-treatment lot.
3.6
sample

either a quantity of molten metal, product or products which are used for the production of specimens

3.7
test specimen

one or more pieces taken from each product in the sample, for the purpose of producing test pieces

3.8
test piece
piece taken from each test specimen and suitably prepared for the test
3.9
test

operation to which the test piece is subjected in order to measure or classify properties

4 Orders or tenders

The order or tender shall define the product required and shall contain the following:

a) the type and form of product:
— the designation of the aluminium or aluminium alloy;
— the form of the product (rod/bar, tube, profile, etc.);

b) the metallurgical temper of the material for delivery (degree of hardness or heat-treatment condition) and,

if different, the metallurgical temper for use;

c) the number of this International Standard or specification number, or, where none exists, the properties

agreed between the supplier and the purchaser;

d) the dimensions and shape of the product (thickness, width, length, diameter); and/or reference to a drawing

defining the product;

e) tolerances of the dimensions and form, with reference to the appropriate International Standard;

f) quantity;
g) any requirements for certificates of conformity, test and/or analysis;

h) any special requirements agreed between the supplier and the purchaser (for example drawings).

5 Requirements
5.1 Production and manufacturing processes

Unless otherwise specified in the order, the production and manufacturing processes shall be left to the

discretion of the producer. Unless it is explicitly stated otherwise in the order, no obligation shall be placed on

the producer to use the same processes for subsequent and similar orders.

ISO 6362-1:2012(E)
5.2 Quality control

The supplier shall be responsible for the performances of all inspection and tests required by the relevant

International Standard, specification or customer requests, prior to shipment of the product. If the purchaser

wishes to inspect the product at the supplier’s works, he shall notify the supplier at the time of placing the order.

5.3 Chemical composition

The chemical composition shall comply with the requirements specified in ISO 6362-7.

If the purchaser requires content limits for elements not specified in ISO 6362-7, these limits shall be stated in

the order document.
5.4 Mechanical properties

The mechanical properties shall be in conformity with those specified in ISO 6362-2 or those agreed upon

between the supplier and purchaser and stated in the order.
5.5  Surface finish

The products shall be free from defects detrimental to its required use and performance. Whilst an operation

designed to mask a fault is not permitted, the elimination of a superficial fault is permissible, provided that the

dimensional tolerances remain.
5.6 Dimensional tolerances
The dimensions and form tolerances shall be:
— in accordance with ISO 6362-3 for extruded rectangular bars;
— in accordance with ISO 6362-4 for extruded profiles;
