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 6362-5 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 6362-5:2001), 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
