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 15912 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 2, Prosthodontic
materials.
This first edition of ISO 15912 contains the requirements and test methods for dental casting, brazing and
refractory investment and die materials. It cancels and replaces ISO 7490:2000, ISO 9694:1996,
ISO 11244:1999, ISO 11245:1999 and ISO 11246:1996.
In general, this International Standard contains the same or similar requirements to those contained in the five
International Standards it replaces. An exception is the requirement for setting expansion, which has been
removed due to the continuing inability to find a suitably reliable and reproducible test method for all binder
chemistries.

ISO 15912:2006(E)
Introduction
Dental investment and other refractory materials are used for a variety of applications within the dental
laboratory. Historically, standards were developed on the basis of the chemistry of the binding system used or
specific type of application, resulting in five separate International Standards. This single International
Standard gives the requirements and test methods for dental casting, brazing and refractory investments and
refractory die materials, regardless of the nature of the binding system or the particular application.
This International Standard classifies investments into types according to their intended use and classes
according to the recommended burn-out procedure.
A specific quantitative requirement for setting expansion is not included in this International Standard.
However, if the setting expansion of a gypsum-bonded investment is measured, use of the procedure
contained in ISO 6873:1998 should be considered. This procedure is not recommended for
phosphate-bonded products.
