SIT ISO11925-2 Single Flame Source Tester is designed and manufactured in accordance with DIN 53438 & ISO 11925-2 standard.
It uses the German Kleinbrenner principle to determine the combustion properties of building materials under direct impact from a small vertical flame. It is applicable to building material categories of B, C, D, E, Bfl, Cfl, Dfl and Efl testing.
This Single Flame Source Tester also meets DIN 4102-Part 1-Class B2 test requirements.
The combustion chamber is made from corrosion resistant stainless steel, to maximize operating life.
SIT ISO11925-2 Single Flame Source Tester has large front and side doors for easy access. These are glazed with toughened glass for full view of the specimen during a test.
An extensively adjustable burner assembly, mounted on runners, to enable the small premixed flame to be tilted at an angle of 45degree to the specimen and offered to it in one fluid movement.
Specimen holder capable of housing the specimens up to and including 60 mm thick.
A fully adjustable specimen support frame facilitating lateral movement of the specimen holder so that the flame can be applied either at the specimen centre position, or at laterally spaced points.
Multilayer specimen holder
Loose fill specimen holder
Anemometer 0-10 m/s range
Timing device with 0.2 sec divisions
Pressure reducing valve: Between 10 kPa and 50 kPa
