(Main)Fire resistance tests for loadbearing elements - Part 2: Floors and roofs
Fire resistance tests for loadbearing elements - Part 2: Floors and roofs
This European Standard specifies a method for determining the fire resistance of:
- floor constructions, without cavities or with unventilated cavities;
- roof constructions, with or without cavities (ventilated or unventilated);
- floor and roof constructions incorporating glazing;
with fire exposure from the underside.
This European Standard is used in conjunction with EN 1363-1.
Feuerwiderstandsprüfungen für tragende Bauteile - Teil 2: Decken und Dächer
Diese Europäische Norm legt ein Prüfverfahren zur Bestimmung der Feuerwiderstandsdauer von
- Deckenkonstruktionen ohne Hohlräume oder mit nicht belüfteten Hohlräumen;
- Dachkonstruktionen mit oder ohne Hohlräume(n) (belüftet oder unbelüftet);
- Decken- und Dachkonstruktionen unter Einbeziehung einer Verglasung;
fest, wobei die Beflammung von der Unterseite aus erfolgt.
Diese Europäische Norm gilt in Verbindung mit EN 1363 1.
Essais de résistance au feu des éléments porteurs - Partie 2: Planchers et toitures
La présente Norme européenne prescrit une méthode pour déterminer la résistance au feu :
- des planchers, sans plenum ou avec plenums non ventilés ;
- des toitures avec ou sans plenums (ventilés ou non) ;
- des planchers et des toitures comportant des vitrages ;
avec une exposition au feu par le dessous.
La présente Norme européenne est utilisée conjointement avec l’EN 1363-1.
Preskusi požarne odpornosti nosilnih elementov - 2. del: Stropi in strehe
Ta evropski standard določa metodo za ugotavljanje požarne odpornosti:
– stropnih konstrukcij, brez lukenj ali z luknjami brez prezračevanja;
– strešnih konstrukcij, z ali brez lukenj (z ali brez prezračevanja);
– stropnih in strešnih konstrukcij z zasteklitvijo;
za izpostavljenostjo požaru z zunanje strani.
Ta standard se uporablja v povezavi s standardom EN 1363-1.

The heating and pressure conditions and the furnace atmosphere shall conform to those given in EN 1363-1 or, if applicable, EN 1363-2. b)
In addition to a) the following applies: -
The furnace pressure conditions shall be established 100 mm below the pressure reference line, see Figure 1. -
For inclined test specimen, the furnace pressure conditions shall be established 100 mm below the pressure reference line at the highest possible position, see Figures 1 and 2. 5.2 Loading conditions The test specimen shall be subjected to loads determined in accordance with EN 1363-1. The determination of the load shall be clearly indicated in the test report. The magnitude and the distribution of the load shall be such that the maximum moments and shear forces produced in the test specimen are representative of, or higher than those expected in practice. The load shall be applied uniformly, e.g. by a point loading system. Point loads shall be transferred to the test specimen through distribution plates; the total contact area between these and the floor surface shall be not more than 0,09 m2 individually, or 16 % of the total surface area collectively. If the plates are made of steel or of materials with a similar high conductivity, they shall be insulated from the surface of the test specimen. The loading equipment shall not inhibit the free movement of air at the top of the test specimen and, other than at the loading points, no part of the loading equipment shall be closer than 60 mm to the unexposed surface of the test specimen. 6 Test specimen 6.1 General Additional guidance on design of roof and floor constructions incorporating glazing is given in Annex A.
