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 3630-6 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 4, WG 9
Endodontic instruments.
ISO 3630 consists of the following parts, under the general title Dentistry — Endodontic instruments:
— Part 1: General requirements
— Part 2: Enlargers
— Part 3: Compactors: pluggers and spreaders
— Part 4: Auxiliary instruments
— Part 5: Shaping and cleaning instruments Part 6: Numeric coding system
— Part 7: Ultrasonic endodontic inserts

Introduction
This document is intended to replace part 5 of ISO 6360 for number coding of endodontic instruments.
The number coding format of the parts of ISO 6360 has been modified as provided below. This document
also makes provisions for the information provided in all of the parts of ISO 6360 and as such is the
only document needed for endodontic instruments.
It establishes a comprehensive numeric coding system suitable for all endodontic instruments by using
a 12-digit code identifying general and specific characteristics of instruments or groups of instruments.
Some of the code digits are quantitative. These codes are detailed within this document.

5 Code numeric for specific characteristics of endodontic instruments
5.1 Type of endodontic instrument
Group A consists of three digits which identify the type of the instrument or item as specified in Table 2.
The group is subdivided into three elements, illustrating the cross section of the active part, the tip of
the instrument and the movement of the instrument. The movement is that carried out by the dentist
when using the instrument during an endodontic procedure.
5.1.1 Cross-sections
Digit 1 describes the cross section of the instrument from “0” to “9”
