Lighters - Safety specification (ISO 9994:2005)
This International Standard establishes requirements for lighters to ensure a reasonable degree of safety for normal use or reasonably foreseeable misuse of such lighters by users. The safety specification given in this International Standard applies to all flame-producing products commonly known as cigarette lighters, cigar lighters and pipe lighters. It does not apply to matches, nor does it apply to other flame-producing products intended solely for igniting materials other than cigarettes, cigars, and pipes. Lighters, being flame-producing devices, can, as do all flame sources, present a potential hazard to users. The safety specification given in this International Standard cannot eliminate all hazards, but is intended to reduce potential hazards to users.
Feuerzeuge - Festlegungen für die Sicherheit (ISO 9994:2005)
Diese Internationale Norm legt Anforderungen für Feuerzeuge im Hinblick auf ein vernünftiges Sicherheitsniveau bei bestimmungsgemäßem Gebrauch oder bei vorhersehbarem, beabsichtigtem Missbrauch durch den Benutzer fest.
Die in dieser Internationalen Norm enthaltenen Festlegungen zur Sicherheit beziehen sich auf alle flammenerzeugenden Produkte, die allgemein als Feuerzeuge für Zigaretten, Zigarrenanzünder und Pfeifenanzünder bekannt sind. Die Festlegungen beziehen sich nicht auf Streichhölzer oder andere flammenproduzierenden Produkte, sondern ausschließlich auf Produkte, die zum Anzünden von Zigaretten, Zigarren und Pfeifen gedacht sind.
Feuerzeuge sowie alle Einrichtungen, die Flammen erzeugen, können wie alle Flammenquellen ein potenzielles Risiko für den Benutzer darstellen. Die in dieser Internationalen Norm enthaltenen sicherheitstechnischen Festlegungen können nicht alle Risiken ausschließen, sie sind aber dazu bestimmt, das potenzielle Risiko für den Benutzer zu reduzieren.
Briquets - Spécifications de sécurité (ISO 9994:2005)
L'ISO 9994:2005 établit des exigences relatives aux briquets qui permettent d'assurer aux utilisateurs un niveau de sécurité raisonnable lors de leur usage normal ou anormal mais raisonnablement prévisible.
Les spécifications de sécurité contenues dans l'ISO 9994:2005 couvrent tous les produits de consommation produisant une flamme, communément désignés sous les appellations de briquets pour cigarettes, briquets pour cigares et briquets pour pipes. Elle n'est applicable ni aux allumettes, ni aux dispositifs produisant une flamme destinée uniquement à allumer des matériaux autres que des cigarettes, des cigares et des pipes.
Comme n'importe quelle source de feu, les briquets peuvent présenter un risque potentiel pour les utilisateurs. Les spécifications de sécurité données dans l'ISO 9994:2005 ne sont pas à même d'éliminer tous les dangers, mais elles sont destinées à réduire les risques potentiels encourus par l'utilisateur.

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 9994 was prepared by Technical Committee ISO/TC 61, Plastics.
This fourth edition cancels and replaces the third edition (ISO 9994:2002). The main change is the inclusion of
safety symbols (see Subclause 6.4).
