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 documents 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).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade 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 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 previous edition are as follows:

a) in the Introduction and Clause 2, EN 12421:1998 has been replaced by EN 12421:2017;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.

Introduction

This document 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 document are

identical to those in EN 12421:2017.
