Medical device software - Software life-cycle processes

Defines the life cycle requirements for medical device software. The set of processes, activities, and tasks described in this standard establishes a common framework for medical device software life cycle processes. Applies to the development and maintenance of medical device software when software is itself a medical device or when software is an embedded or integral part of the final medical device. This standard does not cover validation and final release of the medical device, even when the medical device consists entirely of software.

Logiciels de dispositifs médicaux - Processus du cycle de vie du logiciel

Définit les exigences du cycle de vie des logiciels de dispositifs médicaux. L'ensemble des processus, activités et tâches décrit dans la présente norme constitue un cadre commun pour les processus du cycle de vie des logiciels de dispositifs médicaux. S'applique au développement et à la maintenance des logiciels de dispositifs médicaux lorsque le logiciel est un dispositif médical ou lorsque le logiciel est incorporé ou fait partie intégrante du dispositif médical final. La présente norme ne couvre pas la validation et la mise sur le marché du dispositif médical, même lorsque le dispositif médical est intégralement constitué du logiciel.

Programska oprema za medicinske aparate – Procesi v življenjskem ciklu programske opreme (IEC 62304:2006)

Ta standard določa zahteve glede življenjskega cikla programske opreme za medicinske aparate. Nabor procesov, dejavnosti in opravil, opisanih v tem standardu, tvori skupno ogrodje za procese v življenjskem ciklu programske opreme za medicinske aparate. Ta standard se uporablja za razvoj in vzdrževanje programske opreme za medicinske aparate. Ta standard se lahko uporablja, kadar je programska oprema sama po sebi medicinskiaparat ali je vgrajen/sestavni del končne medicinskega aparata.

This European Standard was approved by CENELEC on 2006-06-01. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Cyprus, the Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,

Foreword
The text of document 62A/523/FDIS, future edition 1 of IEC 62304, prepared by a joint working group of
SC 62A, Common aspects of electrical equipment used in medical practice, of IEC technical committee
62, Electrical equipment in medical practice, and ISO Technical Committee 210, Quality management
and corresponding general aspects for medical devices, was submitted to the IEC-CENELEC parallel
vote and was approved by CENELEC as EN 62304 on 2006-06-01.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2007-03-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2009-06-01
In this standard the following print types are used:
– requirements and definitions: in roman type;
– informative material appearing outside of tables, such as notes, examples and references: in smaller
type. Normative text of tables is also in a smaller type;
– terms used throughout this standard that have been defined in Clause 3 and also given in the index: IN
SMALL CAPITALS.
An asterisk (*) as the first character of a title or at the beginning of a paragraph indicates that there is
guidance related to that item in Annex B.
Table C.5 was prepared by ISO/IEC JTC 1/SC 7, Software and system engineering.
Annex ZA has been added by CENELEC.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
