Metal panel with a gloss white coat on one face Mean thickness (mm) 3.1 Mean weight per unit area (kg/m 2 ) 8.1 Test face White coated face Sample receipt date 12 February 2015 Commercial in Confidence BRE Global Ltd 2015 Page 3 of 11

5 3 Conditioning The specimens were conditioned as required by the standards. 4 BS 476-7: Surface spread of flame of products 4.1 Objective To test and classify the sample described in Section 2 of this report to the surface spread of flame characteristics, as shown by the surface spread of flame test and criteria of British Standard 476: Part 7: 1997 (1). 4.2 Details of test Test Date 12 March 2015 Test Format The specimens were tested were tested with 12mm calcium silicate boards placed behind. 4.3 Results Flame spread data Observed spread of flame for each specimen at 1.5 minutes, 10 minutes and time to reach maximum flame spread distance. Test Run Specimen Flame spread distance at 1.5 minutes (mm) Flame spread distance at 10 minutes (mm) Time to reach maximum flame spread distance (minutes:seconds) : : : : : :50 Commercial in Confidence BRE Global Ltd 2015 Page 4 of 11

6 Time to reach each reference point in seconds if applicable. Test run Specimen Time to reach each reference point (mm) in minutes:seconds Observations. Specimen Observations 1 Flaming to 50mm at 50 seconds, out at 60 seconds. 2 Flaming to 50mm at 55 seconds, out at 60 seconds. 3 Flaming to 50mm at 47 seconds, out at 60 seconds. 4 Flaming to 50mm at 45 seconds, out at 60 seconds. 5 Flaming to 50mm at 55 seconds, out at 60 seconds. 6 Flaming to 50mm at 50 seconds, out at 60 seconds.

7 4.5 Classification Exposed surfaces of materials used as linings for walls and ceilings are classified in Section 11 of the standard according to the rate and distance of spread of flame across them as shown below. Classification Spread of flame at 1.5min Final spread of flame Limit Limit for one specimen in sample Limit Limit for one specimen in sample mm mm mm mm Class Class Class Class 4 Exceeding the limits of Class Summary of results The results of this test show that the above sample as described in Section 2 of this report, when tested and classified in accordance with BS 476: Part 7: 1997, achieved Class 1.

10 BS 6853: A1: 2002 Annex B.2 toxic fume, R, Area based test 5.4 Objective The test was conducted in accordance with the procedure specified in Annex B.2 of BS 6853: A1: 2002 Code of practice for fire precautions in the design and construction of passenger carrying trains (3) - Determination of weighted summation of toxic fume R, and this report should be read in conjunction with this test standard. Four samples as described in Section 2 of this report, each measuring 75mm x 75mm were tested, in flaming mode only. The sampling of the evolved gases was undertaken when 85% of the Ds max value was achieved. The concentrations of hydrogen cyanide, carbon monoxide, carbon dioxide, sulphur dioxide and nitrogen oxides were determined using Dräger colorimeter tubes, the concentrations of hydrogen chloride, hydrogen fluoride, and hydrogen bromide were undertaken using High Performance Ion Chromatography. 5.5 Details of test Test Date 23 February Test results Species Mass Generated by 1 m 2 * (grams) Reference Value Calculated R* Values Carbon dioxide Carbon monoxide Hydrogen fluoride Hydrogen chloride Hydrogen bromide Hydrogen cyanide Nitrogen dioxide Sulphur dioxide R = 1.1 * Average of three replicate tests Commercial in Confidence BRE Global Ltd 2015 Page 9 of 11

11 The Limit of Quantification (LOQ) for HF and HCl = 0.10 mg/l The Limit of Quantification (LOQ) for HBr = 0.34 mg/l The Limit of Quantification (LOQ) for SO 2 = 20 PPM The Limit of Quantification (LOQ) for HCN, NO 2, CO = 2 PPM The Limit of Quantification (LOQ) for CO 2 = 1000 PPM The Limit of Quantification (LOQ) for CO = 5PPM 5.7 Summary of results The sample described in Section 2 of this report, when tested in accordance with BS 6853: 1999 Annex B.2 Incorporating Amendment No.1, achieved an R value of Criteria The requirements of Table 5 exterior vertical surfaces of BS 6853: 1999, are Test method Parameter Vehicle category Ia Ib II BS476-7 Surface spread of flame (worst permissible class) Class 1 (VL surfaces: Class 2) Class 1 (VL surfaces: Class 2) Class 2 Annex D panel test A 0 (ON) (max) A 0 (OFF (max) No criterion No criterion Annex B2 R (max) No criterion 7 Conclusion The sample described in Section 2 of this report, when subjected to the tests required by Table 5 Exterior vertical surfaces of BS 6853: A1: 2002, satisfied the criteria for: Vehicle Category Ia.

12 8 Validity The test results relate only to the behaviour of the test specimens of the product under the particular conditions of these tests; they are not intended to be the sole criterion for assessing the potential fire hazard of the product in use. The specification and interpretation of fire 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 practise, and if required may endorse the test report. 9 References 1 British Standard 476: Part 7: Fire tests on building materials and structures.
