Dentistry - Metallic materials for fixed and removable restorations and appliances (ISO 22674:2016)
ISO 22674:2016 classifies metallic materials that are suitable for the fabrication of dental restorations and appliances, including metallic materials recommended for use either with or without a ceramic veneer, or recommended for both uses, and specifies their requirements. Furthermore, it specifies requirements with respect to packaging and marking the products and to the instructions to be supplied for the use of these materials, including products delivered for sale to a third party.
ISO 22674:2016 does not apply to alloys for dental amalgam (ISO 24234), dental brazing materials (ISO 9333), or metallic materials for orthodontic appliances (ISO 15841) (e.g. wires, brackets, bands and screws).
Zahnheilkunde - Metallische Werkstoffe für festsitzenden und herausnehmbaren Zahnersatz und Applikationen (ISO 22674:2016)
Diese Internationale Norm teilt metallische Werkstoffe, die zur Herstellung von dentalen Restaurationen und
Applikationen geeignet sind, einschließlich der metallischen Werkstoffe, die für eine Anwendung mit oder
ohne Keramikverblendung oder für beide Anwendungen empfohlen werden, in Typen ein und legt deren
Anforderungen fest. Darüber hinaus werden Anforderungen an die Verpackung und Kennzeichnung der
Produkte sowie an die mit der Anwendung dieser Werkstoffe und die für einen Verkauf der Produkte an
Dritte zur Verfügung zu stellenden Anweisungen festgelegt.
Diese Internationale Norm gilt nicht für Legierungen für dentale Amalgame (ISO 24234), dentale Hartlote
(ISO 9333) oder für metallische Werkstoffe für kieferorthopädische Apparaturen (ISO 15841) (z. B. Drähte,
Brackets, Bänder und Schrauben).
Médecine bucco-dentaire - Matériaux métalliques pour les restaurations fixes et amovibles et les appareillages (ISO 22674:2016)
ISO 22674:2016 spécifie une classification des matériaux métalliques appropriés à la fabrication de restaurations dentaires et des appareils, y compris les matériaux métalliques d'utilisation recommandée avec ou sans revêtement céramique, ou indifféremment pour ces deux utilisations, et spécifie les exigences qui leur sont applicables. De plus, elle précise les exigences relatives au conditionnement et au marquage des produits et les instructions à fournir pour l'utilisation de ces matériaux, y compris les produits commercialisés à des tiers.
ISO 22674:2016 ne s'applique pas aux alliages pour amalgame dentaire (ISO 24234), aux produits pour brasage dentaire (ISO 9333) ni aux matériaux métalliques destinés aux appareils orthodontiques (ISO 15841) (par exemple fils métalliques, supports, bagues et vis).
