Prefabricated accessories for roofing - Individual rooflights of plastics - Product specification and test methods

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.
NOTE   Guidelines for safety, application, use and maintenance of individual rooflights are presented in Annex A.

Predizdelani dodatki za ostrešja - Plastični svetlobniki - Specifikacija izdelka in preskusne metode

Ta evropski standard velja za svetlobnike s pravokotnim ali okroglim tlorisom (glej sliki 1 in 2), z razponom odprtine (širine) 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 komponente 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 oporne točke, 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.
OPOMBA: Smernice glede varnosti, aplikacije, uporabe in vzdrževanja posameznih svetlobnikov so podane v Dodatku A.

European foreword This document (EN 1873:2014+A1:2016) has been prepared by Technical Committee CEN/TC 128 “Roof covering products for discontinuous laying and products for wall cladding”, the secretariat of which is held by NBN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by August 2016, and conflicting national standards shall be withdrawn at the latest by August 2016. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document includes Amendment 1 approved by CEN on 2015-12-07. This document supersedes !EN 1873:2014". The start and finish of text introduced or altered by amendment is indicated in the text by tags !". This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with the EU Regulation concerning the CPR, see informative Annex ZA, which is an integral part of this document. !deleted text" According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

1 Scope This European Standard 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.
