1 Scope
This Technical Specification specifies a method for determining the following:
-
a) 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.
-
b) fire damper operational reliability in the petroleum, petrochemical and natural gas industries, particularly offshore installations;
NOTE It is planned to determine the methodology during the testing and development phase.
-
c) ability of fire dampers installed in ventilation systems to withstand blast overpressures that may result from the explosion of a flammable gas.
This Technical Specification 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.
