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).

Coal preparation: Terminology and performance.
This third edition cancels and replaces the second edition (ISO 1213-1:1993), which has been technically
revised.

Introduction
This document takes into account the distinction between processes or operations and the methods or
machines for carrying them out.
Clause 3 is devoted primarily to coal properties and the principal operations involved in coal
preparation, and also includes general terms such as those relating to capacities and flowsheets.
Clauses 4 to 7 cover the detailed terminology relating to sizing, cleaning, separation of solids from
water or air, and size reduction.
Clause 8 deals with the terms involved in interpreting or expressing the results of coal preparation
operations.
Clause 9 includes some miscellaneous terms.
Clause 10 covers terms related to blending and homogenization.
Clause 11 covers terms related to automatic control. Of necessity, it covers only a limited selection of
terms. A list of other International Standards, which together provide a more comprehensive set of
terms, is given in Bibliography.
Most of the clauses are subdivided, and in each case the first subclause includes general terms and the
remaining subclauses cover groups of related terms. As far as possible, this logical principle has been
carried through into the arrangement of the terms themselves, which are also numbered for ease of
reference. An alphabetical index is also provided, with a numerical cross-reference.
