      External Fire Spread<\/em><\/td>\r\n Considered Failed: If temperature rise above Ts<\/sub> of any of the external thermocouples at level 2 exceeds 600\u00b0C for a period of at least 30s, within 15 mins of start time, ts<\/sub>.<\/td>\r\n <\/tr>\r\n
      Internal Fire Spread<\/em><\/td>\r\n Considered Failed: If visible flaming which exceeds the confines of the test vertically\/ sideways during the full 1 hr testing period for more than 60s.<\/td>\r\n <\/tr>\r\n
      Mechanical Performance<\/em><\/td>\r\n Considered Failed: If there is any collapse of the system\/parts (At least 500mm length & 200 gm) onto the floor within the full 1 hr testing period.<\/td>\r\n <\/tr>\r\n
      Burning Debris & Pool Fires<\/em><\/td>\r\n Considered Failed: If burning debris\/ fire pool develops on the floor of test facility during full 1 hr testing period.<\/td>\r\n <\/tr>\r\n
      Additional requirement<\/em><\/td>\r\n <\/td>\r\n Considered Failed: Where fire reaches the internal surface, with duration in excess of 60s on the test specimen at height: 0.5m above combustion chamber opening within 15 mins of start time, ts<\/sub>.<\/td>\r\n <\/tr>\r\n
      Field of Application (thickness, density, cavity depths)<\/em><\/td>\r\n The thinnest and thickest insulation for a given system type, where other specifications remained unchanged shall be tested.
