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 7271 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 7271:1982), which has been technically revised.

INTERNATIONAL STANDARD ISO 7271:2011(E)
Aluminium and aluminium alloys — Foil and thin strip —
Dimensional tolerances
1 Scope

This International Standard specifies dimensional tolerances for aluminium and aluminium alloy foil and thin

strip for general purposes.
It is applicable to the following types of product, shipped in rolls:

⎯ double-rolled foil, of aluminium or aluminium alloys having a minimum mass fraction of aluminium of 98 %,

with one side matt and the other side bright, and of thicknesses in the range 0,006 mm (6 µm) to

0,050 mm (50 µm) inclusive;

⎯ single-rolled foil and thin strip, of aluminium or aluminium alloys having a minimum mass fraction of

aluminium of 98 % or of alloys shown in Annex A or similar, with both sides the same, and of thicknesses

in the range 0,021 mm (21 µm) to 0,200 mm (200 µm).

NOTE According to the conventions in use in different countries, the limit of the thickness range can be different.

The most commonly used general engineering alloys for foil are specified in Annex A.
