40、l 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 establ
41、ished 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 magnitu
42、de 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 tes
43、t specimen through distribution plates; the total contact area between these and the floor surface shall be not more than 0,09 m2individually, 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 fro
44、m 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 G

DIN EN 1365-2:2015-02 EN 1365-2:2014 (E) 8 6.2 Size a) The test specimen shall be full size unless the actual size is larger than can be accommodated in the furnace. b) When the actual siz
46、e cannot be accommodated in the furnace, the dimensions of the test construction shall be such that at least the following dimensions of the test specimen are exposed to the fire: - exposed length (Lexp): 4 m; - exposed width (Wexp): 3 m. One way spanning floor or roof constructions, without ceiling
47、s, may have an exposed width between 2 m and 3 m, provided the relevant requirements given in 6.4 are accommodated. For floor and roof constructions with suspended or self supporting ceilings, Lexpand Wexpshall be related to the surface of the ceiling. c) For floor or roof constructions with structu
48、ral members that span one way only, the following specifications with respect to the span and length of the test specimen apply: - span (Lsup): Lexpplus up to half the length of the bearing at each end. The length of the bearing shall be selected so that the difference between Lsup and Lexp is kept
49、to a minimum or as in practice, whichever is the smaller. - length (Lspec): Lexpplus up to 500 mm at each end (see Figure 3). d) For floor or roof constructions with structural members that span two ways, 6.2 c) applies to the main span. The span and width of the test specimen in the other direction shall be: - span (Wsup): Wexpplus up to half the length of the bearing at each end; - width (Wspec): Wexpplus up to 500 mm at each end. 6.3 Number 6.3.1 General One test specimen shall be tested for each specified support/restraint, or exposure and loading
