In addition, depending upon inclination of the product during the test, the letters EXT.F will be added to indicate “flat or horizontal” and EXT.S will be added to indicate “inclined”.\nTest method\nClass\nClassification criteria\nCR1187:2001 test 1\nBROOF (t1)\nAll of the following conditions must be satisfied:\nexternal and internal fire spread upwards < 0,700 m,\nexternal and internal fire spread downwards < 0,600 m,\nmaximum burned length external and internal < 0,800 m,\nno burning material (droplets or debris) falling from exposed side,\nno burning/glowing particles penetrating the roof construction,\nno single through opening > 2,5 × 10–5 m2,\nsum of all through openings < 4,5 × 10–3 m2,\nlateral fire spread does not reach the edges of the measurement zone,\nno internal glowing combustion,\nmaximum redius of fire spread on ‘horizontal’, roofs, external and internal < 0,200 m.\nFROOF (t1)\nNo performance determined\nCR1187:2001 test 2\nBROOF (t2)\nFor both test series at 2 m/s and 4 m/s wind speed:\nmean damaged length of the roofing and underlay ≤ 0,550 m,\nmaximum damaged length of the roofing and underlay ≤ 0,800 m,\nFROOF (t2)\nNo performance determined\nCR1187:2001 test 3\nBROOF (t3)\nTE ≥ 30 min and TP ≥ 30 min\nCROOF (t3)\nTE ≥ 10 min and TP ≥ 15 min\nDROOF (t3)\nTP> 5 min\nFROOF (t3)\nNo performance determined\nENV 1187:2002 test 4\nB ROOF (t4)\nAll of the following conditions must be satisfied:\nNo penetration of roof system within 1 hour\nIn the preliminary test, after withdrawal of test flame, specimens burn for < 5 minutes\nIn the preliminary test, flame spread < 0.38 m across the region of burning\nC ROOF (t4)\nAll of the following conditions must be satisfied:\nNo penetration of roof system within 30 minutes\nIn the preliminary test, after withdrawal of test flame, specimens burn for < 5 minutes\nIn the preliminary test, flame spread < 0.38 m across the region of burning\nD ROOF (t4)\nAll of the following conditions must be satisfied:\nRoof system is penetrated within 30 minutes but is not penetrated in the preliminary flame test\nIn the preliminary test, after withdrawal of test flame, specimens burn for < 5 minutes\nIn the preliminary test, flame spread < 0.38 m across the region of burning\nE ROOF (t4)\nAll of the following conditions must be satisfied:\nRoof system is penetrated within 30 minutes but is not penetrated in the preliminary flame test\nFlame spread is not controlled\nF ROOF (t4)\nNo performance determined",
