BS EN 1873:2014+A1:2016EN 1873:2014+A1:2016 (E) 7 1 Scope This European Standard specifies requirements for rooflights ma
38、de 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
39、 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 appli
40、es 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 dev
41、ices 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 Europ
42、ean Standard does not include calculations with regard to construction, design requirements and installation techniques.
