Prefabricated accessories for roofing - Individual roof lights of plastics - Product specification and test methods
This European Standard specifies requirements for roof lights made of plastic materials (e.g. GF-UP, PC, PMMA, PVC) with and without upstands made of e.g. GF-UP, PVC, steel, aluminium or wood for installation in roofs. These roof lights serve the purpose of lighting by means of daylight and of ventilating interior spaces by means of opening devices.
This European Standard applies to roof lights 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 roof lights which contribute to the load-bearing or stiffness of the roof itself.
This European Standard applies to roof lights without upstand and to roof lights, where a single manufacturer provides all components of the roof light with upstand, which are bought in a single purchase.
The possible additional functions of smoke and heat ventilation in case of fire, and/or roof access, are outside the scope of this European Standard.
This European Standard does not include calculation with regard to construction, design requirements and installation techniques.
NOTE Guidelines for safety, application, use and maintenance of individual roof lights are presented in Annex A.
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) — mit und ohne Aufsetzkränze(n) aus z. B. GF-UP, PVC, Stahl, Aluminium oder Holz — zum
Einbau in Dächern fest. Diese Lichtkuppeln dienen zur Ausleuchtung mit Tageslicht und zum Lüften von
Räumen mittels Öffnungselementen.
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.
Diese Europäische Norm gilt für Lichtkuppeln ohne Aufsetzkränze und für solche Lichtkuppeln, bei denen ein
einzelner Hersteller sämtliche Bauteile einer Lichtkuppel mit Aufsetzkranz bereitstellt, und die in einem
einzelnen Kauf erworben werden.
Mögliche zusätzliche Funktionen als Rauch- und Wärmeabzug im Brandfall und/oder als Dachausstieg liegen
außerhalb des Anwendungsbereichs dieser Europäischen Norm.
Berechnungen hinsichtlich Konstruktion, Auslegungsanforderungen und Einbauverfahren sind in dieser
Europäischen Norm nicht enthalten.
ANMERKUNG Leitlinien im Hinblick auf Sicherheit, Einbau, Anwendung und Wartung von Lichtkuppeln sind im
Anhang A aufgeführt.

The degree of total luminous transmittance of each skin and possible combinations of skins in new plastic roof lights shall be stated by the manufacturer when measured with a spectrophotometer according to 6.1 either on a flat specimen and/or a finished product. The recorded τD65 value of the total luminous transmittance shall be within ± 5 % of the stated value. NOTE Annex C presents information regarding the calculation of radiation related to energy consumption. 5.2 Durability 5.2.1 General Durability of the product is evaluated by measuring the variation of total luminous transmittance, yellowness index and mechanical properties after ageing procedure of the roof light material with the same energy level for the three following characteristics either on flat sheets and/or finished product. The ageing procedure shall be conducted in accordance with 6.2. 5.2.2 Variation of total luminous transmittance ττττD65 and yellowness index YI (∆∆∆∆YI) Plastic roof lights are classified in 9 types as given in Table 1.

Where required, the variation of the properties shall be determined by a bending test (or a tensile test) as defined in 6.2.4. The percentage reduction in Young’s Modulus, E, and tensile strength, 1, between new samples and samples aged to energy exposures (Hc) as described in Table 1, shall then be expressed in accordance with Tables 2 and 3.

5.3 Water tightness 5.3.1 Roof lights with upstand This characteristic shall be assessed when subject to regulatory requirements and may be assessed otherwise. The plastic roof light in the closed condition shall be tested in accordance with 6.3. No water shall drop from the internal surface. The design of the roof light shall ensure that water drains away. 5.3.2 Roof lights without upstand This characteristic shall be assessed when subject to regulatory requirements and may be assessed otherwise. The products covered by this European Standard are water impermeable provided that they are free of defects such as holes. The absence of such defects shall be checked by visual inspection of the finished product. 5.4 Mechanical performances 5.4.1 Resistance to upward loads This characteristic shall be assessed when subject to regulatory requirements and may be assessed otherwise. According to their resistance to upward loads, plastic roof lights are classified into one of the three types as given in Table 4. Table 4 — Types of upward loads Type Load N/m2 UL 1500 1 500 UL 3000 3 000 UL A a A a a The value of A can be selected to meet specific requirements.
The designations UL 1500, UL 3000 and UL A are representing the test upward load in N/m2 applied, when the roof light is tested in accordance with 6.4.1. When tested in accordance with 6.4.1, the plastic roof light shall be capable of resisting the test load.
EN 1873:2005 (E) 14 A successful test is achieved if neither damage nor permanent deformation occurs which would affect the performance in use (e.g. watertightness, opening). 5.4.2 Resistance to downward loads This characteristic shall be assessed when subject to regulatory requirements and may be assessed otherwise. According to their resistance to downward loads, plastic roof lights are classified into one of the five types as given in Table 5. Table 5 — Types of downward loads Type Load N/m2 DL 750 750 DL 1125 1 125 DL 1750 1 750 DL 2500 2 500 DL A a A a a The value of A can be selected to meet specific requirements.
The designations DL 750, DL 1175, DL 1750, DL 2500 and DL A are representing the test downward load in N/m² applied, when the rooflight is tested in accordance with 6.4.1. When tested in accordance with 6.4.1, the plastic roof light shall be capable of resisting the test load. A successful test is achieved if neither damage nor permanent deformation occurs which would affect the performance in use (e.g. watertightness, opening). 5.4.3 Impact load 5.4.3.1 Small, hard body This characteristic shall be assessed when subject to regulatory requirements and may be assessed otherwise. The product shall be tested in accordance with 6.4.2.1. Plastic roof lights shall be resistant to the impact of a small hard body. The products shall always be tested with the manufacturer's corresponding or specified upstand. NOTE The identification of the tested assembly (the roof light and the upstand) is part of the information accompanying the declared performance. 5.4.3.2 Large, soft body This characteristic shall be assessed when subject to regulatory requirements and may be assessed otherwise. The product shall be tested in accordance with 6.4.2.2. Plastic roof lights wit
