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 15225 was prepared by Technical Committee ISO/TC 210, Quality management and corresponding

general aspects for medical devices.

This second edition cancels and replaces the first edition (ISO 15225:2000), which has been technically

revised. It also incorporates the Amendment ISO 15225:2000/Amd.1:2004.

Introduction

This International Standard is intended to assist competent authorities, conformity assessment bodies,

healthcare providers and manufacturers in the submission and exchange of information. It is intended that the

information covered by this International Standard be available in the public domain.

This second edition of this International Standard is based on experience gained from utilization of the first

edition. The following major changes have been made to the first edition:

⎯ definitions have been added in Clause 3 for base concept, collective term, device category, device type,

generic device group, Global Medical Device Nomenclature (GMDN), GMDN agency, multiple-linked

synonym, product specifier and template specifier;

⎯ Codes 13, 14 and 15 have been added in Annex A, and the descriptions have been updated with

examples of new technologies;
⎯ Annex D has been added containing examples of collective terms.

The requirements contained in this International Standard are applicable to the development and updating of

an international nomenclature and have been prepared specifically for construction of the Global Medical

Device Nomenclature (GMDN).

4 Principle of structure
4.1 General

The nomenclature is structured in four stages. These stages differ in the breadth of the sets of devices

represented by the terms defined within each stage. All medical devices can be classified within each stage.

The stages have a relational structure in the following order:
a) device category (see 4.2);
b) collective term (see 4.3);
c) generic device group (see 4.4);
d) device type (see 4.5).
4 © ISO 2010 – All rights reserved
---------------------- Page: 16 ----------------------
SIST EN ISO 15225:2010
ISO 15225:2010(E)
4.2 Device category

Individual categories have broad usage definitions representing disparate devices that have common areas of

intended use or common technology. Device category has the largest number of devices covered by each

term.

For data organization, device category includes the record holding a device category term and associated

data, such as its code and other attributes.
4.3 Collective term
Collective terms are terms used in the nomenclature for:

a) grouping together preferred terms with common characteristics, e.g. common technology, materials,

medical specialties, manufacturing processes;
NOTE Collective terms can replace or support template terms.

b) illustrating the scope of certificates issued by certification bodies when assessing which groups, families

or types of medical devices are covered within a manufacturer’s quality system;

c) identifying the range of skills and general technological abilities for which a notified body has been

approved, and is so appointed by the relevant regulatory authority;

d) exchanging of information between regulatory authorities when general information on individual

manufacturers capabilities is notified for inclusion within data-exchange systems.

Collective terms are linked directly to preferred terms.
4.4 Generic device group

A generic device group contains sets of devices having the same or similar intended uses or commonality of

technology. Sets of devices are grouped together for the purpose of device vigilance reporting, or other

purposes where sets of essentially similar devices from different sources need to be collected. Potentially, any

device attribute (e.g. implant/non-implant, sterile/non-sterile) can be used as a means of arranging associated

data.

For data organization, the generic device group includes the record holding a device group term. The device

group term can include the following:
a) preferred term (see 5.2.3);
b) template term (see 5.2.4);
c) synonym (see 5.2.5);
d) multiple-linked synonym (see 5.2.6).
It can also include associated data, as follows:
⎯ code;
⎯ definition;

⎯ for synonyms or multiple-linked synonyms, code of the generic device group record holding the preferred

term or template term;
⎯ for templates, the template specifier.

ISO 15225:2010(E)
4.5 Device type

A device type contains individual medical devices including devices intended for clinical investigation, devices

intended for performance evaluation and custom-made devices or sets of medical devices including variants

which may be produced. Device types contain sufficient characteristics in common for the manufacturer to

establish a make and model.

For data organization, device type includes the record holding the device type designation and its associated

data, such as its code and other attributes.
Names to be stored are drawn from the manufacturer’s documentation.

Definition: A surgical instrument typically used in pairs to facilitate correct cranial orientation of

craniofacial implants (e.g., fixation plates being attached to jaw bones) and other devices (e.g.

Generic device group:

craniofacial distractors) during their application in craniofacial surgery. It is typically designed as

a long, thin, rigid rod made of high-grade stainless steel or titanium alloy with connectors at either

end for attachment to the devices being aligned; it may have a knurled mid section (to provide

better grip) onto which other instruments can be locked to assist the orientation procedure. This

is a reusable device.
