Ophthalmic optics - Spectacle frames - Requirements and test methods (ISO/FDIS 12870:2024)
This document specifies fundamental requirements and their test methods for unglazed spectacle frames designed for use with prescription lenses. It is applicable to spectacle frames at the point of sale by the manufacturer or supplier to the retailer.
This document is applicable to:
— all mass-produced spectacle frame types, including rimless mounts, semi-rimless mounts and folding spectacle frames;
— spectacle frames made with additive manufacturing, for example, 3D printing;
— spectacle frames made from natural organic materials;
— the frame or mount of clip-ons designed specifically for attachment to particular models of spectacle frame, but not to their lenses or filters to which ISO 16034 or ISO 12312-1 apply;
— prescription inserts designed for attachment to particular models of, for example, eye protector, sunglass or diving mask.
Parts of this document are applicable to custom-made frames – see 3.1.3 and Table 1.
NOTE See Annex A for recommendations on the design of spectacle frames and terms to be used when describing metal frames.
This document is not applicable to spectacle frames used in eye protection, where ISO 16321-1 applies, or to sunglasses with afocal filters, where ISO 12312-1 applies.
Augenoptik - Brillenfassungen - Anforderungen und Prüfverfahren (ISO/FDIS 12870:2024)
Dieses Dokument legt grundlegende Anforderungen und deren Prüfverfahren für unverglaste Brillenfassungen fest, die zur Verwendung mit Korrektionsgläsern bestimmt sind. Es ist zum Zeitpunkt des Verkaufs der Brillenfassung durch den Hersteller oder Lieferant an den Wiederverkäufer gültig.
Dieses Dokument ist anwendbar für:
alle serienmäßig hergestellten Brillenfassungsarten, einschließlich randloser, halb-randloser und faltbarer Brillenfassungen;
Brillenfassungen, die durch additive Fertigung, z. B. 3-D-Druck, hergestellt werden;
Brillenfassungen aus natürlichen organischen Materialien;
die Fassung oder die Halterung von Aufsteckscheiben, die speziell für die Befestigung an bestimmten Modellen von Brillenfassungen ausgelegt sind, nicht jedoch an deren Brillengläser oder Filter, für die ISO 16034 oder ISO 12312 1 gilt;
Korrektionseinsätze, die für die Befestigung an bestimmten Modellen von z. B. Augenschutz, Sonnenbrillen oder Tauchmasken ausgelegt sind.
Teile dieses Dokuments sind anwendbar für als Sonderanfertigung angefertigte Brillenfassungen – siehe 3.1.3 und Tabelle 1.
ANMERKUNG Siehe Anhang A für Empfehlungen zur Konstruktion von Brillenfassungen und zur Beschreibung von Metallfassungen zu verwendende Benennungen.
Dieses Dokument ist nicht anwendbar für Brillenfassungen für den Augenschutz, für die ISO 16321 1 gilt, oder für Sonnenbrillen mit afokalen Filtern, für die ISO 12312 1 gilt.
Optique ophtalmique - Montures de lunettes - Exigences et méthodes d'essai (ISO/FDIS 12870:2024)
Le présent document spécifie les exigences fondamentales et leurs méthodes d’essai relatives aux montures de lunettes dépourvues de verre conçues pour être équipées de verres correcteurs. Il est applicable aux montures de lunettes au point de vente par le fabricant ou le fournisseur jusqu’au détaillant.
Le présent document est applicable:
— à tous les types de montures de lunettes produites en masse, y compris les montures non cerclées, les montures semi-cerclées et les montures pliables;
— aux montures de lunettes produites par fabrication additive, par exemple, impression 3D;
— aux montures de lunettes en matériaux organiques naturels;
— aux montures ou contre-verres («clip-ons») spécifiquement conçus pour être fixés à des modèles particuliers de montures de lunettes, mais pas à leurs verres ou filtres pour lesquels l’ISO 16034 ou l’ISO 12312-1 s’appliquent;
— aux inserts ophtalmiques conçus pour être fixés à des modèles particuliers de protecteurs des yeux, lunettes de soleil ou masques de plongée, par exemple.
Les parties du présent document sont applicables aux montures fabriquées sur mesure – voir 3.1.3 et Tableau 1.
NOTE Voir l’Annexe A pour ce qui concerne les recommandations relatives à la conception des montures de lunettes et les termes à utiliser lors de la description des montures de lunettes en métal.
Le présent document n’est applicable ni aux montures de lunettes utilisées pour la protection des yeux, pour lesquelles l’ISO 16321-1 s’applique, ni aux lunettes de soleil équipées de filtres afocaux, pour lesquelles l’ISO 12312-1 s’applique.
