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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 79, Light metals and their alloys, Subcommittee
SC 4, Unalloyed (refined) aluminium ingots.
This second edition cancels and replaces the first edition (ISO 115:2003), which has been technically revised.
The main changes are as follows:
— five grades were added to Table 2.

and composition
1 Scope
This document defines the requirements for grades of unalloyed aluminium ingots intended for remelting.

produced, their properties and the marks by which they are identified.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
No terms and definitions are listed in this document.

4 Order
The order, in the form agreed upon between the supplier and the purchaser, shall contain the following
information:
a) designation of the unalloyed aluminium in accordance with this document or the customer code after
agreement between the supplier and the purchaser;
b) specification of the form of the products, including the mass and dimensions of individual ingots and
bundles;
c) quantity: mass, in tonnes (quantity tolerances if required);
d) any requirements for certificates of conformity, test and/or analysis reports or inspection certificates;
e) any additional requirements agreed between the supplier and the purchaser.
5 Requirements
5.1 Production and manufacturing processes
The production and manufacturing processes shall be left to the discretion of the manufacturer.
No obligation shall be placed on the manufacturer to use the same processes for subsequent and similar orders.
5.2 Quality control
The supplier shall be responsible for carrying out all inspection and tests required by this document prior to
shipment of the product. If the purchaser wishes to inspect the product at the supplier's works, the purchaser
shall stipulate this at the time of placing the order.
5.3 Chemical composition
Each grade of unalloyed aluminium, including refined aluminium, with a specified minimum aluminium
content shall be in accordance with the designations and chemical composition given in Table 1.
Each grade of unalloyed aluminium without a specified minimum aluminium content shall be in accordance
with the designations and chemical compositions given in Table 2.
The compositions, except that for aluminium, shown in Table 1 and Table 2 are given in maximum mass
fractions, in per cent.
For the interpretation of the results of chemical analysis, the number representing the result of the
determination of an element content shall be rounded to the same number of decimal places as the
corresponding number in this document.
The writing rules for designations and chemical compositions shall be applied in accordance with Annex A.
If the purchaser requires content limits for elements not specified in this document, these limits shall be
stated on the order, after agreement between the supplier and the purchaser.

5.4 Freedom from contamination and hazardous materials
The ingots shall be free from asbestos and other hazardous foreign materials and show no indication of
increased radioactivity.
To a standard agreed between the supplier and the purchaser, the ingots shall be free from a) to c), if they
are harmful in use:
a) visible surface conditions and contamination such as grease, dirt, products of corrosion, dross or any
other foreign bodies including paint, apart from that which is approved for marking purposes;
b) metallic or non-metallic inclusions;
c) gas porosity.
The ingots may have shrinkage holes or cavities which can retain water. Ingots shall therefore be thoroughly
dried and preheated by the purchaser before charging to a melting furnace, in order to reduce the risk of
