3 1. SUBJECT This classification report defines the resistance to fire classification assigned to Product 110 Envirograf Firoblock 110V15 penetration seal used on a PVC Ventilation trunking penetrating a standard flexible supporting construction, in accordance with the procedures given in EN :2007+A1: DETAILS OF CLASSIFIED PRODUCT 2.1. GENERAL The element, Product 110 Envirograf Firoblock 110V15, is defined as a penetration seal SEPARATING ELEMENT Wall The standard flexible wall construction according to EN :2009, had dimensions of 2000 x 3000 x 100 mm (w x h x t). Between the steel profiles Rockwool insulation was placed with a density of approx. 100 kg/m 3, a thickness of 50 mm and was removed 100 mm around each aperture Profiles In the test frame steel C and U profiles type Knauf UW50 were applied and mounted in the concrete lining with Fischer FNA II 6 x 30/5, c.t.c. 500 mm. Between the top and bottom edge profile, vertical and horizontal profiles type Knauf UW50 were attached with a c.t.c. distance of 600 mm to the edge. The wall was not fixed at the left and right vertical side, the so called free edges, to make unrestrained deflection possible Gypsum board At both sides of the wall, two layers of 15 mm Type F (EN520) gypsum board were applied on the steel profiles. The board was mounted on the steel profiles with drywall screws 3.5 x 25 mm c.t.c. 500 mm and 3.5 x 35 mm for the second (outside) layer, c.t.c 250 mm. The joints between the boards were filled with Knauf filler. This report consists of fourteen pages and may only be used in its entirety. Pagina 3 / 14

4 2.3. PENETRATIONS Penetration seal PVC Ventilation trunking with a dimension of 110 x 54 mm (w x h) fitted with an Envirograf Firoblock 110V15 wrap, applied around the trunking. The wrap protruded 20 mm from the wall surface at the non-fire side and 80 mm from the wall surface at the fire side SERVICE SUPPORT CONSTRUCTION In the test a standard service support construction is used according to EN : 2009 paragraph and figure A.6 in the standard (Test arrangement showing service support construction for flexible wall constructions). The steel service support construction was made from steel C-profiles (thickness approx. 2.5 mm). The pipe and cables were supported on both sides of the wall at a minimum distance of 400 mm from the wall, with steel rods and pipe rings. 3.

5 5. AND DIRECT FIELD OF APPLICATION 5.1. REFERENCE OF This classification has been carried out in accordance with clause 7 of EN :2007+A1: The fire resistance of Product 110 Envirograf Firoblock 110V15 penetration seal used on a PVC Ventilation trunking penetrating a standard flexible supporting construction. Fire resistance classification of: EI 90 E FIELD OF APPLICATION The results of the fire test are directly applicable to similar constructions, where one or more of the changes listed below are made and the construction continues to comply with the appropriate design code for its stiffness and stability Orientation The test results are only applicable to the orientation in which the penetration seals were tested, being a wall Supporting construction The test results are valid for all flexible wall constructions, as mentioned in the EN : 2009, of the same fire resistance classification provided: o The construction is classified in accordance with EN ; o The construction has an overall thickness not less than the minimum thickness of the range given in Table 3 of EN for the standard flexible wall used in the test (100 mm). o The insulation was removed around the penetrations, therefore no aperture framing is needed. o The number of board layers and the overall board layer thickness is equal or greater than that tested (on both sides of the wall, two layers of 12.5 mm gypsum boards); o Flexible wall constructions with timber studs are constructed with at least the same number of layers as given in Table 3 of EN : 2009, no part of the penetration seal is closer than 100 mm to a stud, the cavity is closed between the penetration seal and the stud, and minimum 100 mm of insulation of class A1 or A2 according to EN is provided within the cavity between the penetration seal and the stud. The standard flexible wall construction does not cover sandwich panel constructions and flexible walls where the lining does not cover the studs on both sides. Penetrations in such constructions shall be tested on a case by case basis. The test results apply to concrete or masonry elements of an overall thickness equal to or greater than that of the element used in the test. This report consists of fourteen pages and may only be used in its entirety. Pagina 5 / 14

6 Service support construction The distance from the surface of the separating element to the nearest support position for services shall be 400 mm or less, at both sides Service orientation The service may only penetrate a separating element perpendicular. 6.
