Rooflights and roof hatches - Mechanical properties - Assessment methods and specification of results
Abstract
This European Standard specifies the assessment methods for the determination of the mechanical properties of rooflights and roof hatches to be used on upstands in flat and slightly inclined roofs. This European Standard specifies the assessment methods for: • resistance to uniformly distributed loads resulting from e.g. self-weight, snow, wind and other live loads; • resistance to concentrated live loads; • resistance to impacts of hard and soft bodies and the residual stability of the products afterwards and • resistance to burglary attacks. This document does not cover methods for rooflights or roof hatches which contribute to the structural stability or stiffness of the roof itself. This European Standard applies to rooflights and roof hatches with upstands as well as rooflights and roof hatches supplied without an upstand, intended for use on upstands. This European standard applies to fully factory assembled individual rooflights and roof hatches which are supplied as one unit as well as to continuous rooflights that are supplied in more than one prefabricated sections to be assembled onsite. This European Standard does not apply to: • doors, gates and barriers • windows and roof windows • curtain walling
