Takprodukter - Bestämning av lyftmotståndet hos installerade tegel- eller betongtakpannor - Provningsmetod för taksystem
This document specifies a test method to establish the uplift resistance of installed clay or concrete tiles for roofing, complying with the relevant product standard, EN 490 or EN 1304, which are unfixed or mechanically fixed to the substructure.
NOTE The test method has been developed for clay or concrete tiles for roofing but may apply to other discontinuously laid small elements, such as: slates; fibre cement slates; and, stones.
The test method is applicable to mechanical fixings such as clips, hooks, screws and nails.
In case of mechanically fixed tiles, at least every third tile shall be fixed. The method is not applicable for fixed tiles with fixing patterns with less than every third tile fixed.
The test method is not applicable to under and over tiles. Examples of these tiles are given in Annex H.
