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.

Introduction
Documentation gives rise to numerous international exchanges of both intellectual and material
nature. These exchanges often become difficult, either because of the great variety of terms used in
various fields or languages to express the same concept, or because of the absence, or imprecision, of
useful concepts.
To avoid misunderstandings due to this situation and to facilitate such exchanges, it is advisable to
select terms to be used in various languages or in various countries to express the same concept, and
to establish definitions providing satisfactory equivalents for the various terms in different languages.
The objects involved in the ISO 23472 series are foundry machines used in foundry production.
The purpose of the ISO 23472 series is to provide definitions in English that are rigorous, uncomplicated
and which can be understood by all concerned. The scope of each concept defined has been chosen to
provide a definition that is suitable for general application within foundry machinery, which includes
machines and equipment adapted at each stage of the processes within different casting processes.
As a metal thermoforming method that fills molten metal into the mold to produce machine parts or
rough parts after solidification, casting has a long history and various processes, and its technology
is constantly developing and changing. According to the differences in the mold used, or different
ways of molten metal filling or solidification, casting processes are usually divided into sand casting,
permanent casting and other casting processes. According to different casting processes and different
stages of production, casting equipment covered by foundry machinery is divided into the following
major categories:
— molding and coremaking machines and other equipment related to non-permanent mold casting
process;
— die casting machines and other equipment related to permanent mold casting process;
— abrasive blasting machines and other equipment related to cleaning and finishing for casting;
— cupola furnaces and pouring devices and ladles.
This document only involves terms and definitions of abrasive blasting machines and other equipment
related to cleaning and finishing for casting, including basic concepts specifically concerning structural
characteristics and functions, important mechanisms and parts, main technological processes and
parameters of various abrasive blasting machines, degating devices, decoring machines, grind fettling
machines and other related equipment (see Figure 1).
