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 fourth edition cancels and replaces the third edition (ISO 8287:2011), which has been technically

revised. The main changes compared with the third edition are as follows: a) in Introduction and Clause

2, EN 12421:1998 has been replaced by EN 12421:2017;b) Four new grades of cast unalloyed magnesium

have been added in Table 1, namely ISO Mg99,95C, ISO Mg99,995A, ISO Mg99,995B and ISO Mg99,995C.
