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.

ISO 6362-2 was prepared by Technical Committee ISO/TC 79, Light metals and their alloys, Subcommittee

SC 6, Wrought aluminium and aluminium alloys.

This third edition cancels and replaces the second edition (ISO 6362-2:1990), 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

ISO 6362-1 , Wrought aluminium and aluminium alloys — Extruded rods/bars, tubes and profiles — Part 1: Technical conditions for inspection and delivery

ISO 6892-1, Metallic materials — Tensile testing — Part 1: Method of test at room temperature

ASTM B557M, Standard Test Methods for Tension Testing Wrought and Cast Aluminum- and Alloy Products

Values for mechanical properties of aluminium and aluminium alloys are given in Tables 1 to 3.

For elongation two different gauge lengths are used The choice of the gauge length for elongation measurements

(A or A50mm) is at the discretion of the producer, unless otherwise agreed.

NOTE A is the percentage elongation on a gauge length of 5,65 So A50mm is the percentage elongation on a gauge length of 50 mm

Test results shall be rounded in accordance with the rules given in Annex A.

age-e The mechanical properties of temper grade T62 shall be applied only when the material of temper grade O has been artificially age-hardened after solution treatment by the purchaser If the material is cold or hot worked prior to solution treatment by the purchaser, its mechanical properties may be lower than the specified values

f Applicable for those after extrusion followed by controlled cooling at a rate rapid enough to hold constituents in solution

In the case of the tensile test made before completion of 1 month of natural ageing, the tensile performance of temper grade T4 may

be deemed as guaranteed if the test result of the test piece which has been artificially aged after solution treatment is confirmed to satisfy the tensile performance of temper grade T6

`,,```,,,,````-`-`,,`,,`,`,,` -A.1 Rounding of results obtained by inspection and testing

The results of mechanical and chemical tests shall be rounded using either the rules specified in the International Standard specifying the method of test or, if the value obtained contains a larger number of significant figures than the guaranteed value, the generally accepted rules for rounding.

A.1.2 Dimensional characteristics

The results of determinations of dimensions (length, width, thickness, rounding, etc.) and shape (squaring, cambering, straightness, flatness, kinking, circularity, etc.) are not rounded These shall comply with the specification in the relevant International Standard, taking into account permissible tolerances also given in that International Standard.

A.2 Rounding of determination of compliance

In recording test results, the number representing the result of a test to determine a given property or to determine chemical composition should be expressed to the same number of decimal places as the corresponding number in the relevant International Standard.

The following rules should be used for rounding.

a) When the figure immediately after the last figure to be retained is less than 5, the last figure to be retained remains unchanged.

b) When the figure immediately after the last figure to be retained is greater than 5, or equal to 5 and followed

by at least one figure other than zero, the last figure to be retained remains unchanged if even and is increased by one if odd.

c) When the figure immediately after the last figure to be retained is equal to 5 and followed by zeros only, the last figure to be retained remains unchanged if even and is increased by one if odd.
