Overview

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; it is planned to determine a suitable 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. German Working Committee NA 109-00-01 AA "Materialien, Ausrüstungen und Offshore-Bauwerke für die Erdöl-, petrochemische und Erdgasindustrie - Spiegelausschuss zu CEN/TC und ISO/TC 67" ("Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries - Mirror Committee of CEN/TC and ISO/TC 67") of the Petroleum and Natural Gas Industries Standards Committee (NÖG) of DIN, the German Institute for Standardization e. V. has collaborated.
