Eye and face protection - Protection against laser radiation - Part 1: Requirements and test methods (ISO 19818-1:2021)

This document is applicable to protectors intended to provide protection against accidental exposure to laser radiation within the wavelength range 180 nm to 1 mm. It specifies the requirements, test methods and marking. Protectors intended for adjustment work on lasers are included in the scope of this document and are marked in the same way as other protectors, but selection of appropriate eyewear for a specific application is a choice of the user. Laser protective filters used as viewing windows in laser equipment machinery or incorporated into optical instruments such as operating microscopes and loupes that may be used for deliberate viewing of laser radiation as part of their function are outside the scope of this document.
Laser radiation in the wavelength range below 180 nm is absorbed in air, therefore eye and face protection should not be required.
This document is applicable to devices intended for patient protection during medical laser procedures except for treatment in the periorbital area. Guidance on eye protectors for patients (including those used for periorbital treatment) is given in ISO/TR 22463.

Augen- und Gesichtsschutz - Schutz vor Laserstrahlung - Teil 1: Anforderungen und Prüfverfahren (ISO 19818-1:2021)

Dieses Dokument ist anwendbarfür Schutzgeräte, die zum Schutz gegen unbeabsichtigt einwirkende Laserstrahlung im Wellenlängenbereich zwischen 180 nm bis 1 mm vorgesehen sind. Es legt die Anforderungen, Prüfverfahren und die Kennzeichnungen fest. Schutzgeräte, die für Justierarbeiten an Lasern vorgesehen sind, sind vom Anwendungsbereich dieses Dokuments abgedeckt und werden wie andere Schutzgeräte gekennzeichnet, allerdings ist die Auswahl der geeigneten Brille für eine bestimmte Anwendung eine Entscheidung des Anwenders. Laserschutzfilter, die als Sichtfenster in Laseranlagen verwendet werden oder in optische Instrumente wie Operationsmikroskope und Lupen eingebaut sind, die als Teil ihrer Funktion zur gezielten Betrachtung von Laserstrahlung verwendet werden dürfen, liegen nicht im Anwendungsbereich dieses Dokuments.
Laserstrahlung im Wellenlängenbereich unter 180 nm wird in Luft absorbiert, daher sollte kein Augen- und Gesichtsschutz erforderlich sein.
Dieses Dokument ist für Geräte anwendbar, die zum Schutz des Patienten bei medizinischen Laserverfahren vorgesehen sind, mit Ausnahme der Behandlung im periorbitalen Bereich. Ein Leitfaden zu Augenschutz¬geräten für Patienten (einschließlich derjenigen zur periorbitalen Behandlung) ist in ISO/TR 22463 enthalten.

Protection des yeux et du visage - Protection contre le rayonnement laser - Partie 1: Exigences et méthodes d'essai (ISO 19818-1:2021)

Le présent document est applicable aux protecteurs destinés à fournir une protection contre une exposition accidentelle à un rayonnement laser dans une gamme de longueurs d’onde comprise entre 180 nm et 1 mm. Il spécifie les exigences, les méthodes d’essai et le marquage. Les protecteurs destinés aux travaux de réglage sur les lasers sont inclus dans le domaine d’application du présent document et comportent le même marquage que les autres protecteurs, mais il incombe à l’utilisateur de choisir la lunette appropriée à une application spécifique. Les filtres de protection laser utilisés comme fenêtre d’observation dans les machines d’équipements laser ou incorporés dans les instruments optiques tels que des microscopes opératoires et des loupes qui peuvent être utilisés pour l’observation intentionnelle du rayonnement laser dans le cadre de leur fonctionnement n’entrent pas dans le domaine d’application du présent document.
Le rayonnement laser dont la gamme de longueurs d’onde est inférieure à 180 nm est absorbé dans l’air, par conséquent il convient que la protection des yeux et du visage ne soit pas exigée.
Le présent document s’applique aux dispositifs destinés à la protection du patient lors d’une intervention médicale au laser à l’exception des traitements dans la région périorbitaire. Des recommandations relatives aux protecteurs des yeux destinés aux patients (y compris ceux utilisés pour les traitements périorbitaires) sont données dans l’ISO/TR 22463.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
