1 CLASSIFICATION OF FIRE RESISTANCE PERFORMANCE IN ACCORDANCE WITH EN : 2007 Sponsor: Reynaers Aluminium NV/SA Oude Liersebaan 266 B-2570 Duffel BELGIUM Prepared by: Efectis Nederland B.V. Centre for Fire Safety Lange Kleiweg 5 P.O. Box BC RIJSWIJK, The Netherlands Notified Body No: 1234 Product name: Aluminium curtain wall structure type CW 50-FP Classification report no.: 2007-Efectis-R0669 Issue number: 01 Projectnumber: Date of issue: February 2008 This report is issued by the TNO company Efectis Nederland BV (previously TNO Centre for Fire Research). TNO decided, in response to international developments and requests by customers, to collaborate with two European Egolf partners, both highly experienced in fire safety: the Norwegian Sintef/NBL and the French CTICM. Thus, through scaling up, a more comprehensive service of high quality and a wider range of facilities can be offered. In order to achieve this, the fire safety related activities of the partners involved have been privatised in this collaboration. With respect to TNO this has led to the privatisation on the 1 st of July 2006 of the activities of the TNO Centre for Fire Research via the establishment of the company Efectis Nederland BV. This classification report consists of five pages and may only be used or reproduced in its entirety. 1

2 1. Introduction This classification report defines the classification in accordance with the procedures given in EN :2007.assigned to a curtain wall structure type CW 50-FP manufactured from aluminium sections integrated with steel tubes and cooling material and provided with fire-resistant glazing and panels 2. Details of classified product 2.1 General An aluminium curtain wall structure, type CW 50-FP. 2.2 Product description The curtain wall, type CW 50-FP with main dimensions 4530 x 3700 mm (w x h) was subdivided by aluminium mullions and transoms into 18 bays, 4 bays were fitted with Glaverbell insulating glass, type Pyrobel EG and 14 bays were fitted with WPI insulated panels with glass face plate. WPI panels, thickness 49 mm or 104 mm. The mullions consist of aluminium sections, dimensions of 46 x 46 mm with an integrated tube with dimensions of 40 x 40 x 4 mm. The transoms consist of aluminium sections with dimensions of 45 x 45 mm, provided with Kerafix Coolmax cooling material, dimensions 10 x 45 mm. The transoms were attached to the mullions by means of aluminium T-brackets and stainlesssteel bolts. For fitting of the mullions to the concrete frame structure, anchors of type CW 60 were fitted to the framework at the corner points. Aluminium pressure plates are fitted into PVC screw channels, used for vertical and horizontal compartimentation, by means of stainless-steel screws with a spacing of 300 mm and steel plates with dimensions of 40 x 40 x 3 mm. The steel plates are used to secure the vertical and horizontal fixation of the glass in case of a fire. The pressure plates are covered with aluminium caps with integrated Kerafix S-board. For sealing against the glazing and the panels, EPDM sealings are fitted into the mullions and transoms. The glass panes and panels are located on different steel glass supports. The mullions were at the top of the construction provided with a separation at the position of the top floor to create a better thermal insulation to profiles which cross the separation floor. The construction is fully described in the test reports provided in support of classification listed in Clause Test reports & test results in support of classification 3.1 Test reports Name of Laboratory Name of sponsor Test report No. Test method Efectis Nederland BV Centre for Fire Safety Reynaers Aluminium NV/SA 2007-Efectis-R Efectis-R Efectis-R0668 EN :2006 EN :2006 EN :2007 2

4 4. Classification and field of application 4.1 Reference of classification This classification has been carried out in accordance with clause 7 of EN : Classification The aluminium curtain wall structure, type CW 50-FP, manufactured from aluminium sections integrated with steel tubes and cooling material and provided with fire-resistant glazing and panels is classified according to the following combinations of performance parameters and classes as appropriate. Fire resistance classification: E 60(o i) EI 60 (o i) EW 60 (i o) 4.3 Field of application This classification is valid for an aluminium curtain wall structure which is the same in detail as the tested structure and which comply with the following conditions: - aluminium profiles, type CW50-FP integrated with steel tubes; - transoms provided with Kerafix Coolmax cooling material; - Glaverbel glass, type Pyrobel EG with maximum dimensions of 1580 x 2458 mm (w x h) and a maximum area of 3.47 m 2 ; - WPI panels, thickness 49 mm with maximum dimensions of 1218 x 1580 mm (w x h) and a maximum area of 0.87 m 2 ; - WPI panels, thickness 104 mm with maximum dimensions of 1218 x 1580 mm (w x h) and a maximum area of 1.92 m 2 ; - panels and glass panes distributed over the curtain wall as tested; - the edges of the glass panes and panels provided with the specified EPDM sealing; - profiles fixed with T-brackets, type CW 60; - glass panes and panels supported with the specified steel supports; - between the glass panes or panels and the steel supports aluminium silicate glass support blocks; - in the rebate around the perimeter, self adhesive intumescent material, type Kerafix flextrem; - horizontal and vertical sections and pressure plates insulated with Kerafix-S Board; - design of the edge junctions as specified in the report. - Profiles at the top provided with separation for extra thermal insulation. 4

5 The test results are valid for curtain walling systems of increased width provided the construction details (distance of mullions etc.) are the same as the one tested. The results are valid for curtain walling systems of greater height (extending over more than one floor) provided the distance between the floors is equal to or smaller than that tested. 5.
