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).

Introduction

Lithium minerals, lithium compounds, lithium metal and lithium alloys are widely used. Different businesses and industry sectors have various descriptions for lithium compounds, alloys. Therefore, it is of vital importance to unify the terminology used in the lithium industry.

Lithium minerals and brines are the main sources of lithium to date. Various lithium compounds and alloys are obtained from lithium minerals or brines as they are processed through to intermediate products and on to final products such as battery materials, etc.

This document is expected to be used by producers, consumers and traders in the field of lithium minerals, compounds, alloys and scrap recycling. This document can serve as a reference that will help to reduce discrepancies or trade disputes caused by inconsistencies in concepts used when dealing with lithium minerals, lithium compounds, lithium alloys.

1 Scope

This document defines concepts or unification of concepts for lithium minerals, lithium metals, lithium compounds, lithium alloys, and lithium scrap recycling, including concepts related to materials characteristics, physical characteristics, and chemical characteristics.

This document can be used as a reference for concepts and unified concepts in lithium minerals, compounds, alloys and scrap recycling production, application, inspection, circulation, trading, scientific research and education purposes.
