5 Page 5 of 33 Test Procedure Introduction The doorset is required to provide a fire separating function and were therefore tested in accordance with BS EN : 2000 Fire resistance tests for doors and shutter assemblies - Part 1: Fire doors and shutters. This test report should be read in conjunction with that Standard and with BS EN : 1999, Fire resistance tests - Part 1: General requirements and BS EN : 1999, Fire resistance tests - Part 2: Alternative and additional procedures. Prior to testing, the doorset was subjected to 25 manually operated opening and closing cycles as specified in EN 14600: The specimen was judged on its ability to comply with the performance criteria for integrity and insulation, as required by BS EN : The radiation from each doorset was measured in accordance with the requirements of BS EN : Fire Test Study Group/EGOLF Certain aspects of some fire test specifications are open to different interpretations. The Fire Test Study Group and EGOLF have identified a number of such areas and have agreed Resolutions which define common agreement of interpretations between fire test laboratories which are members of the Groups. Where such Resolutions are applicable to this test they have been followed. Instruction To test The test was conducted on the 16 th Haldern the sponsor of the test. May 2007 on behalf of Novoferm GmbH Mr Gunther Schottler and Mr Andrew Sherlock, representatives of the test sponsor, witnessed the test. Test Specimen Construction A comprehensive description of the test construction is given in the Schedule of Components. The description is based on a detailed survey of the specimens and information supplied by the sponsor of the test. The doorset s storage, installation, and test preparation took place in the test laboratory between the 13 th and 16 th May Installation The sponsor supplied the doorsets on the 14 th May The doorsets were mounted within apertures provided within a high density rigid supporting construction such that the door leaves opened away from the heating conditions of the test. Representatives of the sponsor conducted installation on the 14 th May Sampling Bodycote warringtonfire was not involved in any selection or sampling procedures of the specimens or any of their components.

14 Page 14 of 33 Instrumentation General Furnace General Thermocouples 2 to 6 The instrumentation was provided in accordance with the requirements of the Standard. The furnace was controlled so that its mean temperature complied with the requirements of BS EN : 1999 Clause 5.1 using six plate thermometers, distributed over a plane 100 mm from the surface of the test construction. Thermocouples were provided to monitor the unexposed surface of the specimens and the output of all instrumentation was recorded at no less than one minute intervals as follows: At five positions on each doorset, one approximately at the centre and one at approximately the centre of each quarter section of each doorset. Thermocouples 12 to 15 Thermocouples 20 to 23 At four positions on each doorset, positioned at 100 mm in from the door leaf vertical edges, two at mid-height, and two at 100 mm below the top edge of each leaf. At two positions on the top horizontal frame and one position on each vertical frame member at mid-height of each doorframe. The locations and reference numbers of the various unexposed surface thermocouples are shown in Figure 1. Roving Thermocouple Integrity Criteria Radiation Furnace Pressure A roving thermocouple was available to measure temperatures on the unexposed surface of the specimens at any position which might appear to be hotter than the temperatures indicated by the fixed thermocouples. Cotton pads and gap gauges were available to evaluate the integrity of the specimens. Water-cooled foil heat-flux meters were used to record the heat radiation from the specimens. The heat flux meters were positioned at a distance of 1 metre from the unexposed surface of each of the doorset. The furnace atmospheric pressure was controlled so that it complied with the requirements of BS EN : Clause 5.2. The calculated pressure differential relative to the laboratory atmosphere at the top of the specimens was 14.8 (±3) Pa.

30 Page 30 of 33 Performance Criteria and Test Results Integrity It is required that the specimens retain their separating function, without either causing ignition of a cotton pad when applied, or permitting the penetration of a gap gauge as specified in BS EN : 2000, or resulting in sustained flaming on the unexposed surface. These requirements were satisfied for the periods shown below: Integrity performance Sustained flaming 96 minutes Gap gauge Cotton pad 133 minutes* 61 minutes *The test duration. Insulation Insulation performance Radiation The mean temperature rise of the unexposed surface shall not be greater than 140 C and that the maximum temperature rise shall not be greater than 180 C (except on the door frame, where the maximum temperature rise shall not exceed 360 C). Insulation failure also occurs simultaneously with integrity failure as specified in BS EN : These requirements were satisfied for the period shown below: 4 minutes BS EN : 1999 requires that the time for the measured radiation to exceed 5, 10, 15, 20 and 25 kw/m 2 be reported. The readings given below are the average readings for each of the specimens.

31 Page 31 of 33 Ongoing Implications Limitations This report details the method of construction, the test conditions and the results obtained when the specific element of construction described herein was tested following the procedure outlined in BS EN : 1999, and where appropriate BS EN : Any significant deviation with respect to size, constructional details, loads, stresses, edge or end conditions other than those allowed under the field of direct application in the relevant test method is not covered by this report. Annex A of BS EN : 1999, provides guidance information on the application of fire resistance tests and the interpretation of test data. Because of the nature of fire resistance testing and the consequent difficulty in quantifying the uncertainty of measurement of fire resistance, it is not possible to provide a stated degree of accuracy of the result. Conclusions Evaluation against objective Two specimens of single-acting, single-leaf steel based doorsets have been subjected to a fire resistance test in accordance with BS EN : 2000, Fire resistance tests for door and shutter assemblies, BS EN : 1999, General requirements and BS EN : 1999, Alternative and additional procedures. The evaluation of the doorsets against the requirements of the above mentioned standards showed that they satisfied the requirements for the following periods: Test Results: Integrity performance Sustained flaming Gap gauge Cotton Pad *The test duration. 96 minutes 133 minutes* 61 minutes Insulation performance 4 minutes Radiation Performance 5 kw/m 2 10 kw/m 2 15 kw/m 2 20 kw/m 2 25 kw/m 2 Doorset A 49 minutes 102 minutes 133 minutes # 133 minutes # 133 minutes # # Not exceeded during the test.

32 Page 32 of 33 Field of Direct Application General Materials And Constructions, General Specific Restrictions On Materials And Construction Decorative Finishes Frames Hardware Permissible Size Variations Specific Size Variations Of The Doorset Other Changes The field of direct application of results is restricted to governing the allowable changes to the test specimen following a successful fire resistance test. These variations can be introduced automatically without the need for the sponsor to seek additional evaluation, calculation or approval. Unless otherwise stated in the following text the construction of the door assemblies shall be the same as that tested. The number of leaves and the mode of operation (e.g. sliding, swinging, single action or double action) shall not be changed. The thickness of the door leaves shall not be reduced but may be increased. The door leaf thickness and/or density may be increased provided the total increase in weight is not greater than 25%. The type of glass and fixing technique shall not be changed. The quantity and dimensions of glazed apertures may be decreased. The distance between glazed apertures and the perimeter of the door leaf may not be reduced. Paint finishes are acceptable and may be added to the door leaves or frame products. The number of fixings used to attach each doorset to supporting constructions may be increased but shall not be decreased and the distance between fixings may be reduced but shall not be increased. Changes in hardware are permitted provided the alternative hardware has been demonstrated in another doorset of similar configuration. The number of any movement restrictors such as locks, latches and hinges may be increased but shall not be decreased. Doors of sizes different from those of tested specimens are permitted within certain limitations but variations are dependent on the product type and the length of time that the performance criteria are fulfilled. Unlimited size reduction is permitted for the doorsets. Size increase may be permitted, depending on the required classification period, in line with Section 13.3 of BS EN : For smaller door sizes the relative positioning of movement restrictors (e.g. hinges, latches, etc.) shall remain the same as tested or any change to the distances between them will be limited to the same percentage reduction as the decrease of specimen size.

33 Page 33 of 33 Asymmetrical Door Assemblies General Specific Rules Supporting Constructions BS EN states that for separating elements required to be fire resisting from both sides, two specimens shall be tested (one from each direction) unless the element is fully symmetrical. However, in some cases it is possible to develop rules whereby the fire resistance of an asymmetrical door assembly tested in one direction can apply when the fire exposure is from the other direction. The possibility to develop such rules increases if the consideration is limited to certain types of door assembly and on the criteria being applicable, e.g. integrity only doors. The following rules represent the minimum level of common agreement which shall be followed. The rationale behind the rules is given in Annex C of BS EN : The doorsets were asymmetrical and were tested such that they opened away from the furnace chamber. The doorsets conformed with the specific rules given in of BS EN : 2000 which gives details of the applicability of the test results of doorsets tested in one direction to cover the opposite opening direction. The fire resistance of a door assembly tested in one form of standard supporting construction may or may not apply when it is mounted in other types of construction. In some cases it is possible for the result of a test on a particular type of door assembly tested in one form of standard supporting construction to be applicable to that door assembly when mounted in a different type of standard supporting construction.
