Prefabricated accessories for roofing - Individual rooflights of plastics - Product specification and test methods
EN 1873 specifies requirements for rooflights made of plastic materials (e.g. GF-UP, PC, PMMA, PVC) and rooflights with upstands made of e.g. GF-UP, PVC, steel, aluminium or wood for installation in roofs. These rooflights serve the purpose of introducing daylight. This European Standard applies to rooflights with a rectangular or circular ground plan (see Figures 1 and 2), with an opening span (width) or diameter not larger than 2,5 m and an opening length not larger than 3,0 m in roof pitches up to 25°. This document does not cover rooflights which contribute to the load-bearing or stiffness of the roof itself. This European Standard applies to rooflights and rooflights with upstand, where a single manufacturer provides all components of the rooflight with upstand, which are bought in a single purchase. This European Standard applies to rooflights with one or several translucent parts. Rooflights may be opened by means of opening devices in one or more parts for ventilation. The possible additional functions of day to day ventilation, smoke and heat ventilation e.g. in case of fire in accordance with EN 12101-2, roof access, and/ or slinging point e.g. in accordance with EN 795 are outside the scope of this document. This European Standard does not include calculations with regard to construction, design requirements and installation techniques.
Vorgefertigte Zubehörteile für Dacheindeckungen - Lichtkuppeln aus Kunststoff - Produktfestlegungen und Prüfverfahren
Diese Europäische Norm legt Anforderungen an Lichtkuppeln aus Kunststoffmaterialien (z. B. GF UP, PC, PMMA, PVC) und Lichtkuppeln mit Aufsetzkränzen aus z. B. GF UP, PVC, Stahl, Aluminium oder Holz zum Einbau in Dächern fest. Diese Lichtkuppeln dienen zur Beleuchtung mit Tageslicht.
Diese Europäische Norm gilt für Lichtkuppeln mit rechteckigem oder rundem Grundriss (siehe Bilder 1 und 2), mit einer Öffnungsweite (Breite) oder einem Durchmesser von höchstens 2,5 m und einer Öffnungslänge von höchstens 3,0 m in Dachflächen mit Neigungen bis 25°. Dieses Dokument gilt nicht für Lichtkuppeln, die zur Tragfähigkeit oder zur Steifigkeit des Daches selbst beitragen.
Dieses Dokument gilt für Lichtkuppeln und für Lichtkuppeln mit Aufsetzkränzen, bei denen ein einzelner Hersteller sämtliche Bauteile einer Lichtkuppel mit Aufsetzkranz bereitstellt, und die in einem einzelnen Kauf erworben werden.
Dieses Dokument gilt für Lichtkuppeln mit einem oder mehreren lichtdurchlässigen Teilen.
Lichtkuppeln können mittels Öffnungsvorrichtungen in einem oder mehreren Teilen zum Be- und Entlüften geöffnet werden.
Die möglichen zusätzlichen Funktionen als Be- und Entlüftung im Alltag, Rauch und Wärmeabzug, z. B. im Brandfall nach EN 12101-2, als Dachausstieg und/oder Anschlagpunkte z. B. nach EN 795 liegen außerhalb des Anwendungsbereichs dieser Europäischen Norm.
Berechnungen hinsichtlich Konstruktion, Auslegungsanforderungen und Einbauverfahren sind in diesem Dokument nicht enthalten.
ANMERKUNG Leitlinien im Hinblick auf Sicherheit, Einbau, Anwendung und Wartung von Lichtkuppeln sind im Anhang A aufgeführt.
Accessoires préfabriqués pour couverture - Lanterneaux ponctuels en matière plastique - Spécifications des produits et méthodes d'essais
La présente Norme européenne spécifie les exigences pour les lanterneaux en matière plastique (par exemple polyester renforcé par des fibres de verre (PRV), polycarbonate (PC), polyméthacrylate de méthyle (PMMA), polychlorure de vinyle (PVC) avec costières, fabriqués par exemple en PRV, PVC, acier, aluminium ou bois, et destinés à être installés sur des toitures. Ces lanterneaux permettent de laisser passer la lumière du jour.
La présente Norme européenne s’applique aux lanterneaux ayant une embase rectangulaire ou circulaire (voir Figures 1 et 2), dont la portée (largeur) ou le diamètre d’ouverture ne dépasse pas 2,5 m et dont la longueur d’ouverture n’est pas supérieure à 3,0 m sur des toitures en pente jusqu’à 25°. Le présent document ne couvre pas les lanterneaux qui contribuent à la portance ou à la raideur de la toiture proprement dite.
Le présent document s'applique aux lanterneaux simples et aux lanterneaux avec costière dont tous les éléments constitutifs, partie intégrante d'un achat unique, sont fournis par un seul fabricant.
Le présent document s'applique aux lanterneaux avec une ou plusieurs parties translucides.
Les lanterneaux peuvent s'ouvrir au moyen de dispositifs d’ouverture en une ou plusieurs parties pour la ventilation.
Les éventuelles fonctions supplémentaires de ventilation quotidienne, d’évacuation des fumées et de la chaleur, comme par exemple en cas d'incendie, conformément à l'EN 12101-2, d'accès à la toiture, et/ou de points d'ancrage conformes par exemple à l'EN 795, ne relèvent pas du domaine d'application du présent document.
Le présent document ne comprend pas les calculs concernant les constructions, les exigences de conception et les méthodes d'installation.
NOTE Les directives relatives à la sécurité, à l'application, à l'utilisation et à l'entretien des lanterneaux ponctuels sont présentées en Annexe A.
Predizdelani dodatki za ostrešja - Plastični svetlobniki - Specifikacija izdelka in preskusne metode
Standard EN 1873 določa zahteve za svetlobnike iz plastičnih materialov (npr. GF-UP, PC, PMMA, PVC) in svetlobnike s podstavki iz npr. GF-UP, PVC, jekla, aluminija ali lesa za vgradnjo v streho. Namen teh svetlobnikov je prepuščanje dnevne svetlobe. Ta evropski standard velja za svetlobnike s pravokotnim ali okroglim tlorisom (glej sliki 1 in 2) z razponom odprtine (širino) ali premerom, ki ni večji od 2,5 m in dolžino odprtine, ki ni večja od 3,0 m na poševnih strehah z nagibom do 25°. Ta dokument ne zajema svetlobnikov, ki prispevajo k nosilnosti ali togosti strehe. Ta evropski standard velja za svetlobnike in svetlobnike s podstavki, pri katerih en sam proizvajalec zagotavlja vse sestavne dele svetlobnikov s podstavki, ki so kupljeni hkrati. Ta evropski standard velja za svetlobnike z enim ali več prosojnimi deli. Svetlobniki se lahko odprejo s pomočjo naprave za odpiranje, in sicer se lahko odpre en ali več delov za prezračevanje. Morebitne dodatne funkcije za vsakodnevno prezračevanje, prezračevanje dima in toplote, npr. v primeru požara v skladu s standardom EN 12101-2, dostopa na streho in/ali opornih točk, npr. v skladu z EN 795, so izven obsega tega dokumenta. Ta evropski standard ne vključuje izračunov v zvezi z gradnjo, projektiranjem in montažnimi tehnikami.

This European Standard applies to rooflights with one or several translucent parts.
Rooflights may be opened by means of opening devices in one or more parts for ventilation.
The possible additional functions of day to day ventilation, smoke and heat ventilation e.g. in case of fire in
accordance with EN 12101-2, roof access, and/ or slinging point e.g. in accordance with EN 795 are outside
