ISO 3630-1:2008(E)
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 3630-1 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 4, Dental
instruments.
This second edition cancels and replaces the first edition (ISO 3630-1:1992), which has been technically
revised.
ISO 3630 consists of the following parts, under the general title Dentistry — Root-canal instruments:
⎯ Part 1: General requirements and test methods
⎯ Part 2: Enlargers
⎯ Part 3: Condensers, pluggers and spreaders
⎯ Part 4: Auxiliary instruments

ISO 3630-1:2008(E)
Introduction
The reorganization of ISO 3630 is intended to present the requirements and test methods for root-canal
instruments in an orderly manner. This part of ISO 3630 defines general requirements and test methods.
Subsequent parts provide the specific requirements and test methods, if applicable, for two areas of
endodontic procedures. These parts are enlargers, condensers and auxiliary instruments.
With current use of nickel-titanium (Ni-Ti) alloys for manufacture of root canal instruments a need for adequate
expertise in their safe use is recommended. Instruments made of Ni-Ti can be easily broken near the tip if
manufacturer's cautions are not understood and practiced. This part of ISO 3630 does not attempt to provide
information for proper use of any instruments.
[4]
The sizes of the root-canal obturating points (cones) specified in ISO 6877 have to be aligned with the
corresponding sizes for root-canal instruments specified in ISO 3630.
