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 21563 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 2,
Prosthodontic materials.
This first edition of ISO 21563 constitutes a consolidation of the three standards listed below and, as
such, cancels and replaces, in whole, all three of the standards listed.
— ISO 1563:1990, Dentistry — Alginate impression materials
— ISO 1564:1995, Dental aqueous impression materials based on agar
— ISO 13716:1999, Dentistry — Reversible/irreversible hydrocolloid impression materials systems
Re-evaluations of all the provisions stated in the three ISO standards to be included in the consolidation
led to the significant technical changes listed as follows.
— The alginate hydrocolloid impression materials (ISO 1563) are now required to be subject to the
same tear strength test that has been in effect for the agar hydrocolloid impression materials
(ISO 1564 and ISO 13716) instead of being subject to a compressive strength test.
— The requirement for the alginate impression material powder materials to be “free from foreign
materials”, as stated in ISO 1563, has not been carried forward into the consolidation because no
objective test has been specified for determining compliance with the requirement.
— The “gelation temperature” requirements in ISO 1564 and ISO 13716 have not been carried forward
for the agar impression materials because results of the elastic recovery test (7.5), if conducted
following the required manufacturer’s instructions for use (8.2.1 and/or 8.2.2), will indicate
whether adequate gelation will take place during clinical use of the materials.

Dentistry — Hydrocolloid impression materials
1 Scope
This International Standard specifies the requirements and tests for helping determine whether the
elastic aqueous agar and alginate hydrocolloid dental impression materials, as prepared for retail
marketing, are of the quality needed for their intended purposes. It also specifies requirements for
labelling and instructions for use.
NOTE This International Standard specifies no requirements or tests for freedom from unacceptable
biological hazards. However, it is recommended that, to address possible biological hazards associated with the
use of hydrocolloid impression materials, interested p
