4 FOREWORD This structural test report details tests in accordance with BS 5234: Part 2: 1992, Annexes A, B, C, D, E, F, G and L, on a 97mm wide British Gypsum GypWall partition system incorporating Gypframe 70S60 studs at 600 mm centres and clad both sides with a single layer of 12.5mm Rigidur H. The test specimen was installed by. The construction of the specimen took place between the 17 th & 19 th May designed the partition system and selected the materials for the test specimen. played no role in the design or selection of the materials comprising the test specimen. REPORT AUTHORISATION Report Author Authorised by James McLavy BSc. (Hons.), AMIOA, AIFireE Project Leader Phil Barnes BTC Testing Manager Report date: 18 th July 2006 will not discuss the content of this report without written permission from the test sponsor. retains ownership of the test report content but authorises the test sponsor to reproduce the report as necessary in its entirety only.

5 TEST CONSTRUCTION The British Gypsum GypWall partition system was 3600mm high and 4500mm long. One end of the partition was fixed to the test rig and the other end remained free. A door set, measuring 900mm x 2100mm, was incorporated into the partition 700mm from the fixed end. Gypframe 72DC60 Deep Flange Floor & Ceiling Channel was screw fixed to the head of the test frame aperture at 600mm centres. Gypframe 72DC60 Deep Flange Floor & Ceiling Channel was screw fixed to the base of the test frame aperture at 600mm centres with a 900mm wide gap for the door. The base channel was cut and bent up by 300mm to form uprights at the doorjamb positions. The base channel was fixed to the test frame aperture with 4 of No. 10 round head screws. Gypframe 70S60 C studs were positioned between the head and base channels at 600mm centres. Additional Gypframe 70S60 studs were positioned at the doorjambs and fixed into the head and base channels using 13mm Gyproc Wafer Head Jack-Point Screws (one each side of the stud). The 300mm uprights were fixed in position with 13mm Gyproc Wafer Head Jack-Point Screws (two each side of the stud). A Gypframe 72DC60 Deep Flange Floor & Ceiling Channel was located at the head of the door opening. The channel was cut and bent down by 150mm and fitted over the stud positions. The channel was fixed in position with 13mm Gyproc Wafer Head Jack-Point Screws (two each side of the stud). The remainder of the doorjambs were cloaked with Gypframe 72DC60 Deep Flange Floor & Ceiling Channel fixed at 200mm centres using 13mm Gyproc Wafer Head Jack-Point Screws (on each side of the stud). A single layer of 12.5mm Rigidur H board was fixed to each side of the metal framework around the perimeter and within the field of the board using 40mm Glasroc FireCase Screws at 300mm centres. All vertical joints were staggered. Horizontal joints were located at 2400mm from the base on both sides of the partition. Gypframe GFS1 Fixing Strap was used behind the horizontal joint. The joints adjacent to both sides of the door were taped and filled using Gyproc Joint Tape and Gyproc Joint Filler. Customer: BTC 14574S: Page 5 of 40

6 The door casing was fixed into position using two 90mm Gyproc drywall screws at each point 150mm from the bottom of the casing and at 600mm centres thereafter. The architrave and skirting were then fixed to both sides of the partition. 12.5mm Rigidur H Board Gypframe 70S60 'C' Stud 40mm Glasroc FireCase Screws Figure 1. Cross section through the partition system. The descriptions of individual components making up the test specimen were provided by the customer and were checked for accuracy wherever possible.

11 TEST RESULT Classification grade SEVERE DUTY was achieved in accordance with BS 5234: Part 2: 1992 LIMITATIONS The results only relate to the behaviour of the specimen of the element of construction under the particular conditions of test; they are not intended to be the sole criteria for assessing the potential structural performance of the element in use. The specification and interpretation of structural test methods are the subject of ongoing development and refinement. Changes in associated legislation may also occur. For these reasons it is recommended that the relevance of test reports over 5 years old should be considered by the user. The laboratory that issued the report will be able to offer, on behalf of the legal owner, a review of the procedures adopted for a particular test to ensure that they are consistent with current practices, and if required may endorse the test report.

39 APPENDIX A CRITERIA FOR ACCEPTANCE Annex A - Stiffness The maximum deflection and residual deformation shall not exceed the limits for the grade being tested given in the table below. Note. Only superficial cracks which represent aesthetic damage are acceptable. Stiffness: applied loads and deflection. Grade Applied Load N Maximum deflection mm Maximum residual deformation mm LIGHT DUTY MEDIUM DUTY HEAVY DUTY SEVERE DUTY Annex B - Surface damage by a small hard body impact Judgment made on whether the damage is acceptable by the user of the partition based on the description of damage along with photographic evidence held by the laboratory. Note. No specific criteria for acceptance is given because the impact damage will vary with different materials and forms of construction; some surface damage may be acceptable because it can be easily repaired. Annex C - Resistance to damage by impact from a large soft body Partition should be capable of withstanding the impact energies without sustaining either permanent deformation in excess of 2 mm or any damage. Any local damage that can easily be repaired to regain the partitions original properties shall be permitted. Customer: BTC 14574S: Page 39 of 40

40 Annex D - Perforation by small hard body impact No perforation of the partition allowable. Description very vague in the Test Standard so we take perforation to mean exposure of the partition cavity. No requirement for this test for a light duty partition. Annex E - Resistance to structural damage by impact from a large soft body Capable of withstanding the impact energies without collapsing or dislocating the partition or its fixings. Annex F - Door slamming The partition shall not be damage nor shall door frame fittings and architrave become detached or loose after the door leaf has been slammed. The closing jamb of the doorframe shall not be permanently displaced by more than 3 mm as a result of the pre slam test and by more than 1 mm as a result of the main test, from its position at the start of the test. Annex L - Heavyweight anchorage (high level wall cupboard) The maximum deflection during the test shall not exceed 5mm and residual deformation shall not exceed 1mm. The anchorage shall retain the shim plates at the load selected (2000N or 4000N). Annex G - Crowd pressure No collapse or damage that would render the partition dangerous, due to any of its parts becoming dislodged or shattered, in a manner that could cause injury. Note. For partitions that do not collapse and where the damage is not dangerous, any deflection and any damage reported in the test report is for information only. Customer: BTC 14574S: Page 40 of 40
