5 Page 5 of 32 Test Procedure Introduction The doorsets are required to provide a fire separating function and were therefore tested in accordance with BS EN : 2008 Fire resistance and smoke control tests for door, shutter and openable window assemblies and elements of building hardware - Part 1: Fire resistance tests for doors, shutters and openable windows. 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. The specimens were judged on their ability to comply with the performance criteria for integrity and insulation, as required by BS EN : The specific purpose of the test was to evaluate the effects of the inclusion of items of building hardware into a previously tested Doorset construction. Because of this, no direct field of application for the doorsets is included in this report. Fire Test Study Group/EGOLF Instruction to test 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. The test was conducted on the 13 th March 2012 at the request of Simonswerk UK Ltd. the test sponsor. Mr Robin Guy, a representative of the test sponsor, witnessed the test. Test Specimen Construction Installation Sampling Conditioning 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 doorsets were mounted within apertures in a blockwork wall construction such that their door leaves opened towards the heating conditions of the test. Representatives of Exova Warringtonfire conducted the installation work on the 13 th March 2012 The specimen hinges used in the test were sample selected by Mr. J. Corcoran, a representative of Warrington Certification Limited, on the 29 th February The specimens storage, construction, and test preparation took place in the test laboratory over a total combined time of approximately 7 days. Throughout this period both the temperature and the humidity of the laboratory were measured and recorded as being within a range of from 12 o C to 18 o C and 45% to 78% respectively.

13 Page 13 of 32 Instrumentation General Furnace Thermocouple Allocation Thermocouples 2 to 6 Doorset A and 7 to 11 Doorset B Thermocouples 20 to 23 (Doorset A) & Thermocouples 24 to 27 (Doorset B) 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. The output of all instrumentation was recorded at no less than one minute intervals as follows: At five positions on the unexposed surface of the doorset, one approximately at the centre and one at approximately the centre of each quarter section of the doorset. At three positions on the unexposed surface of the door frame, one at the approximate mid-height of each of the vertical frame members and one approximately mid-span of the head member. The locations and reference numbers of the various unexposed surface thermocouples are shown in Figure 1. Roving Thermocouple 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. Integrity Criteria Furnace Pressure Cotton pads and gap gauges were available to evaluate the integrity of the specimens where relevant. After the first five minutes of testing and for the remainder of the test, 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 was 12.9 (±2) at the head of both doorsets.

31 Page 31 of 32 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 : 2008, or resulting in sustained flaming on the unexposed surface. These requirements were satisfied for the periods shown below: Doorset A Doorset B Sustained Flaming 34 minutes* 34 minutes* Cotton wool pad 34 minutes* 34 minutes* Gap gauge 34 minutes* 34 minutes* Insulation Insulation performance 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 periods shown below: Doorset A Doorset B 34 minutes* 34 minutes* *The test duration, the test was discontinued after 34 minutes. 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, and 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.

32 Page 32 of 32 Conclusions Evaluation Against Objective Two specimens of single-acting, single-leaf timber based doorsets, incorporating items of building hardware have been subjected to a fire resistance test in accordance with BS EN : 2008, Fire resistance and smoke control tests for door, shutter and openable window assemblies and elements of building hardware,, BS EN : 1999, General requirements and BS EN : 1999, Alternative and additional procedures. The evaluation of the doorsets against the requirements of BS EN : 2008 showed that the doorsets satisfied the requirements for the following periods. Test Results: Doorset A Doorset B Integrity Sustained Flaming 34 minutes* 34 minutes* Cotton wool pad 34 minutes* 34 minutes* Gap gauge 34 minutes* 34 minutes* Insulation 34 minutes* 34 minutes* *The test duration, the test was discontinued after 34 minutes.
