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 15854 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 2, Prosthodontic
materials.
This first edition cancels and replaces ISO 1561:1995 and ISO 12163:1999, which have been technically
revised.

Introduction
This International Standard does not include specific and quantitative requirements for freedom from biological
hazards. It is recommended that, in assessing possible biological or toxicological hazards, reference be made
to ISO 7405 and ISO 10993-1 (see Bibliography).

This International Standard is applicable to dental casting wax and to dental baseplate wax. It specifies the
classification of, and requirements for, dental casting wax and baseplate wax together with the test methods to
be employed to determine compliance with these requirements.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 1942-2 and the following apply.
3.1
casting wax
mouldable material primarily for shaping patterns in the production of fixed cast restorations using the
“lost-wax” procedure
3.2
baseplate wax
mouldable material primarily for shaping patterns that will be duplicated in denture base polymers, and for
forming occlusion rims and other patterns

1) ISO 3336 and ISO 4824 are to be combined and revised as ISO 22112, Dentistry — Artificial teeth for dental
prostheses.
ISO 15854:2005(E)
4 Classification
Dental waxes covered by this International Standard are classified according to the flow characteristics that
represent their hardness, as follows:
a) Type 1 (casting wax):
1) Class 1 Soft
2) Class 2 Hard
b) Type 2 (baseplate wax):
1) Class 1 Soft
2) Class 2 Hard
3) Class 3 Extra hard
5 Requirements
5.1 Appearance
The wax shall be uniform in colour, supplied in pieces of uniform size, of smooth texture and free of foreign
materials. Test in accordance with 8.1.
5.2 Flow
The samples of the wax when tested in accordance with 8.2 shall have flow properties complying with the
requirements in Table 1.
