Prefabricated accessories for roofing - Individual roof lights of plastics - Product specification and test methods; English version of DIN EN 1873:2006-03
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.
