Dentistry - Gypsum products (ISO 6873:2013)
ISO 6873:2013 gives a classification of, and specifies requirements for, gypsum products used for dental purposes such as making oral impressions, moulds, casts, dies or model bases, and mounting models. It specifies the test methods to be employed to determine compliance with these requirements. It also includes requirements for the labelling of packaging and for adequate instructions to accompany each package.
Zahnheilkunde - Gipse (ISO 6873:2013)
In dieser Internationalen Norm werden Anforderungen festgelegt und eine Typeneinteilung der Gipse vorgenommen, die in der Zahnheilkunde Anwendung finden, wie zum Beispiel bei der Abdrucknahme und der Herstellung von Modellen, Abgüssen, Formen oder Modellsockeln und Montagemodellen. Diese Norm beschreibt die anzuwendenden Prüfverfahren, um die Konformität mit diesen Anforderungen festzustellen. Außerdem enthält sie Anforderungen an die Etikettierung der Verpackungen und an die entsprechende Gebrauchsanweisung, die jeder Packung beizufügen ist.
Diese Internationale Norm gilt nicht für Knochentransplantatersatz für zahnärztliche Zwecke, der aus Calciumsulfat Halbhydrat (oder Dentalgips) besteht.

L'ISO 6873:2013 donne une classification et spécifie des exigences applicables aux produits à base de gypse utilisés à des fins dentaires, tels que la prise d'empreintes buccales, la fabrication de moules, de moulages, de matrices ou de bases de modèles et le montage de modèles. Elle spécifie les méthodes d'essai à appliquer pour déterminer la conformité à ces exigences. Elle inclut également des exigences concernant l'étiquetage des emballages et les instructions appropriées à joindre à chaque emballage.

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.
Specific qualitative and quantitative requirements for freedom from biological hazard are not included
in this International Standard but it is recommended that, in assessing possible biological hazards,
reference should be made to ISO 10993-1 and ISO 7405.
ISO 6873 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 2,
Prosthodontic materials.
This third edition cancels and replaces the second edition (ISO 6873:1998) of which Clause 4 and
subclauses 5.4 and 8.2 have been technically revised. An alternative design for the extensometer used
to measure setting expansion is included.

Introduction
This revision was necessary because gypsum products have been marketed since the last edition of
ISO 6873 was published, which have properties (required for newly introduced dental technology) for
which the requirements set in that edition were not appropriate. In this edition the classification has
been altered to take this into account and in so doing, requirements have been set appropriately. In
addition there was concern that Type 4 dental stone used for CAD/CAM models should not produce
significant setting expansion at times beyond the 2 h period at which setting expansion was measured
and a requirement had been set. In this edition the setting expansion for Type 4 dental stone is measured
at 24 h as well.
