Oxygen concentrators for medical use - Safety requirements (ISO 8359:1996)

IS0 8359 is one of a series of International Standards based on IEC 601-I. In IEC 601-I (the "General Standard"), this type of International Standard is referred to as a "Particular Standard". As stated in 1.3 of IEC 601-I :1988, the requirements of this International Standard take precedence over those of IEC 601-I. The scope and object given in clause 1 of IEC 601-I :I 988 apply, except that 1.1 shall be replaced by the following: This International Standard specifies safety requirements for continuous-flow oxygen concentrators, as defined in 1.3.8 (in this International Standard). This International Standard does not apply to oxygen concentrators intended to supply gas to several patients via a piped medical gas installation or to those intended for use in the presence of flammable anaesthetic and/or cleaning agents. The scope of this International Standard is not restricted to membrane oxygen concentrators and pressure swing absorbers (see Introduction), as alternative methods of concentrating oxygen may become available and it is not intended that this International Standard should restrict future developments.

Sauerstoff-Konzentratoren für medizinische Zwecke - Sicherheitsanforderungen (ISO 8359:1996)

ANMERKUNG Siehe Begründung in Anhang P
ISO 8359 gehört zu einer Reihe von Internationalen Normen, die auf der IEC 601-1 basieren. In IEC 601-1
(der „Allgemeinen Norm“) wird diese Art Internationaler Norm als „Besondere Festlegungen“ bezeichnet. Wie
in 1.3 der IEC 601-1:1988 festgelegt, haben die Anforderungen dieser Internationalen Norm Vorrang vor
denen der IEC 601-1.
Der Anwendungsbereich nach Abschnitt 1 von IEC 601-1:1988 gilt mit der Ausnahme, dass 1.1 durch
Folgendes ersetzt werden muss:
Diese Internationale Norm legt Sicherheitsanforderungen für Sauerstoff-Konzentratoren mit kontinuierlichem
Durchfluss fest, entsprechend der Definition in 3.8 (dieser Internationalen Norm). Diese Internationale Norm
gilt nicht für Sauerstoff-Konzentratoren, die für die Versorgung mehrerer Patienten über eine Zentralversorgungsanlage
für medizinische Gase vorgesehen sind oder zum Einsatz mit entflammbaren Narkoseund/
oder Reinigungsmitteln.
Der Anwendungsbereich dieser Internationalen Norm ist nicht beschränkt auf Membran-Sauerstoff-Konzentratoren
und Druckwechseladsorber (siehe Einleitung), da alternative Verfahren der Sauerstoffanreicherung
entwickelt werden könnten und zukünftige Entwicklungen durch diese Internationale Norm nicht behindert
werden sollten.

Concentrateurs d'oxygène à usage médical - Prescriptions de sécurité (ISO 8359:1996)

L'ISO 8359 fait partie d'une série de Normes internationales basées sur la CEI 601-1. Dans la CEI 601-1 (la «Norme générale»), il est fait référence à ce type de Norme internationale en tant que «Norme particulière». Comme indiqué au paragraphe 1.3 de la CEI 601-1:1988, les prescriptions de la présente Norme internationale ont priorité sur les prescriptions de la CEI 601-1.
Le domaine d'application indiqué à l'article 1 de la CEI 601-1:1988 est applicable, à l'exception du paragraphe 1.1 qui est remplacé par ce qui suit:
La présente Norme internationale prescrit les exigences de sécurité pour les concentrateurs d'oxygène, comme indiqué en 1.3.8 (dans la présente Norme internationale). La présente Norme internationale ne s'applique pas aux concentrateurs d'oxygène prévus pour fournir du gaz à plusieurs patients par l'intermédiaire de conduites de gaz médicaux, ni à ceux prévus pour être utilisés en présence d'anesthésiques et/ou d'agents de nettoyage inflammables.
Le domaine d'application de la présente Norme internationale ne se limite pas aux concentrateurs d'oxygène à membrane et aux appareils à absorption par oscillation (voir Introduction), car il peut exister d'autres méthodes pour concentrer l'oxygène et la présente Norme internationale n'a pas pour but de faire obstacle à des progrès futurs.

Naprave za koncentriranje kisika za uporabo v medicini - Varnostne zahteve (ISO 8359:1996)

Standard ISO 8359 je eden od standardov iz serije mednarodnih standardov, ki temeljijo na standardu IEC 601-I. V standardu IEC 601-I („splošni standard“) se za to vrsto mednarodnega standarda uporablja izraz „poseben standard“. Kot je navedeno v točki 1.3 standarda IEC 601-I:1988, imajo zahteve iz tega mednarodnega standarda prednost pred zahtevami iz standarda IEC 601-I. Veljata področje uporabe in cilj iz točke 1 standarda IEC 601-I:I 988, vendar se točka 1.1 nadomesti z naslednjim: Ta mednarodni standard določa varnostne zahteve za naprave za koncentriranje kisika s stalnim pretokom, kot je opredeljeno v točki 1.3.8 (v tem mednarodnem standardu). Ta mednarodni standard se ne uporablja za naprave za koncentriranje kisika, ki prek medicinskega cevovoda za plin zagotavljajo plin več pacientom ali so namenjene za uporabo v prisotnosti vnetljivih anestetikov in/ali čistilnih sredstev. Področje uporabe tega mednarodnega standarda ni omejeno na membranske naprave za koncentriranje kisika in absorberje nihanja tlaka (glejte Uvod), ker se utegnejo razviti alternativne metode za koncentriranje kisika, pri čemer ta mednarodni standard ne sme ovirati razvoja v prihodnosti.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
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. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
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.
International Standard IS0 8359 was prepared by Technical Committee
lSO/TC 121, Anaesthetic and respiratory equipment, Subcommittee
SC 3, Lung ventilators and related equipment.
This second edition cancels and replaces the first edition
(IS0 8359:1988), which has been technically revised.
Annexes A to N form an integral part of this International Standard. An-
nexes P and Q are for information only.

Introduction
Oxygen concentrators provide a safe source of oxygen-enriched air for
patients in need. These devices raise the level of inspired oxygen by sep-
arating nitrogen or oxygen from ambient air.
Oxygen concentrators fall into two main classes according to the means
whereby gas separation is effected, namely:
a) oxygen concentrators in which oxygen selectively permeates or
transports through a membrane or lattice,
b) pressure swing absorbers (PSA) in which air is exposed at a certain
pressure to molecular sieve material which selectively retains nitrogen
and other components until they are subsequently released when the
pressure is reduced.
Details of the arrangement of test apparatus for carrying out a number of
the tests to check compliance with certain requirements are given in an-
nex N.
A rationale for the most important requirements is given in annex P. It is
considered that a knowledge of the reasons for the requirements will not
only facilitate the proper application of this International Standard, but will
expedite any subsequent revision.
Test methods other than those specified in this International Standard, but
of equal or greater accuracy, may be used to verify compliance with the
given requirements. However, in the event of a dispute, the methods
specified in this International Standard are to be used as the reference
methods.

Section I: General
1.1 Scope
NOTE 1 See the rationale in annex P.
IS0 8359 is one of a series of International Standards based on IEC 601-I. In IEC 601-I (the “General
Standard”), this type of International Standard is referred to as a “Particular Standard”. As stated in 1.3 of
IEC 601-I :1988, the requirements of this International Standard take precedence over those of IEC 601-I.
The scope and object given in clause 1 of IEC 601-I :I 988 apply, except that 1.1 shall be replaced by the following:
This International Standard specifies safety requirements for continuous-flow oxygen concentrators, as defined
in 1.3.8 (in this International Standard). This International Standard does not apply to oxygen concentrators in-
tended to supply gas to several patients via a piped medical gas installation or to those intended for use in the
presence of flammable anaesthetic and/or cleaning agents.
The scope of this International Standard is not restricted to membrane oxygen concentrators and pressure swing
absorbers (see Introduction), as alternative methods of concentrating oxygen may become available and it is not
intended that this International Standard should restrict future developments.
1.2 Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this
International Standard. At the time of publication, the editions indicated were valid. All standards are subject to
revision, and parties to agreements based on this International Standard are encouraged to investigate the possi-
bility of applying the most recent editions of the standards indicated below. Members of IEC and IS0 maintain
registers of currently valid International Standards.
