    ISO 9705 Building Materials Flammability Tester  fire tests—full-scale room test for surface products

     

    Based on Oxygen Consumption Principle GB/T 25207-2010 .The standard is a reference to ISO 9705writing standard of combustion test, the test method to simulate the corner fire scenario as a condition of standard test, and test the installation of the sample completely according to actual use, which is one of the most reliable standard test method.Due to the relatively complex sample quantity and test conditions required by this test, it is usually used in fire science research and to evaluate the combustion characteristics of materials that cannot be correctly evaluated by small size test.


    Applications: building materials, shipping materials
    Standards: DS/ISO/TR 9705-2, ISO 9705:2016 GB 8624:2012, GB/T 25207:2010, GB/T 27904:2011


    The test device consists of four parts, including combustion chamber, flue gas collection and sampling system, gas analysis and data processing system and gas supply system. The test was carried out in a combustion chamber with a sample surface area of about 21 m2 and the door was normally open. The tested materials were installed according to the actual use. A rectangular triangular sand box burner with propane gas was installed at the corner of the inner wall of the room. During the test, the flow rate of gas should be controlled to make the standard heat output of the fire source 100 kW before 10 minutes. When the material did not explode, the flow rate of gas should be adjusted to increase the heat output to 300 kW and last 10 minutes. During a total 20-minute test period, the test can be stopped if there is flashover. The determination of explosive phenomena can be judged by observing and testing curves of heat release rate.


    During the test, the total heat release, heat release rate, flue gas generation and flue gas generation rate were tested.
