Omfang

ISO/TS 27469:2010 specifies a method for determining the following: ability of fire dampers installed in ventilation systems to prevent the spread of fire and heat through designated fire divisions; typical ratings are given in ISO 13702:1999, Table C.5. fire damper operational reliability in the petroleum, petrochemical and natural gas industries, particularly offshore installations; ability of fire dampers installed in ventilation systems to withstand blast overpressures that may result from the explosion of a flammable gas. ISO/TS 27469:2010 applies to different start-up operations for different types of furnace and, therefore, tolerances in test conditions at the beginning of the test are not described in detail. The fire test enables only a limited assessment of the actuating mechanism being carried out and additional tests can be necessary to fully evaluate its operational reliability.
