This European Standard specifies requirements for continuous rooflights made of plastic materials (e.g. GF-UP, PC, PMMA, PVC) with or without bearing profiles to be used with upstands made of e.g. GF-UP, PVC, steel, aluminium, wood or concrete, for laying in roofs, which serve the purpose of lighting by means of daylight and, possibly, of ventilating interior spaces by means of opening devices. This European Standard applies to continuous rooflights without upstand and to continuous rooflights, where a single manufacturer provides all components of the rooflight with upstand, which are bought in a single purchase. Products covered by this European Standard may be supplied as continuous rooflights with and without upstand and rooflights intended to be used with an upstand, for which the upstand is specified, but not supplied. It applies to continuous rooflights when mounted with an inclination ä in the longitudinal direction not more than 10° to the horizontal and not more than 10° in the transversal direction (see Figure 1): a) with bearing profiles: – symmetrical, angled, curved (see Figure 2) or flat (see Figure 3); – constructed with bearing profiles parallel to the span and with a rectangular ground plan; b) without bearing profiles: – symmetrical, angled or curved with an á angle not more than 45° (measured to the horizontal at the line of fixing, see Figure 4); – constructed with a span (width) lower than or equal 2,5 m and with a rectangular ground plan. This European Standard applies to continuous rooflights, including barrel vault rooflights, with a rectangular ground plan of plastic glazing laying in roofs having, in addition a minimum distance of b/3 (b = effective span of rooflights, corresponding to the light opening). The upstands may be self-supporting or non self-supporting. The design of the upstand is not part of this European Standard. Upstands can be prefabricated or site fabricated. Prefabricated upstands are to be considered as part of the continuous rooflight. Site fabricated upstands are not covered by this European Standard. This European Standard does not include calculation with regard to works, design requirements and installation techniques. 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. NOTE 1 – Continuous rooflights outside of the scope of this European Standard will be covered by European Technical Approvals based on EOTA ETA-Guideline 010 "Self supporting translucent roof kits". Individual rooflights are covered by EN 1873. NOTE 2 – Guidelines for safety, application, use and maintenance of continuous rooflights are presented in Annex A.
