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 8287 was prepared by Technical Committee ISO/TC 79, Light metals and their alloys, Subcommittee SC 5,
Magnesium and alloys of cast or wrought magnesium.
This third edition cancels and replaces the second edition (ISO 8287:2000), which has been technically revised.

Introduction
This International Standard classifies commercially available cast unalloyed magnesium into a number of grades
suitable for the applications for which they might be used. The grades listed in this International Standard are
identical to those in EN 12421:1998.
