Title:
FLAME RESISTANCE TEST DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/083591
Kind Code:
A1
Abstract:
In a flame resistance test device equipped with a test tank in which a subject to be tested for flame resistance can be burned, the temperature inside the test tank can be quickly adjusted to a given allowable temperature with a very simple configuration. In response to the detection of a start event, a control unit (6) maintains an exit damper (3) in the open state, maintains a cold air supply switching unit (41, 42) in the state in which cold air is supplied to the inside of the test tank (10), and maintains a draft fan (3) in the operating state of pulling gas out of the test tank (10), until the detection temperature of a temperature sensor (5) drops to a target temperature. When the detection temperature of the temperature sensor (5) drops to the target temperature, the control unit (6) closes the exit damper (3), switches the cold air supply switching unit (41, 42) such that cold air is no longer supplied to the inside of the test tank (10), and stops the operation of the draft fan (2).
