ISO 11925-2 Flammability Tester For Fireproof Building Materials
ISO 11925-2 Ignitability of Building Material Subjected to Direct
Impingement of Flame Single-Flame Source Tester
Application:
It is mainly applicable to test methods to determine whether
building materials have flammability under specified conditions.
Standards:
GB/ T 8626-2007
GB/ T 10801.2-2002
EN ISO 11925-2
DIN 4102
Technical parameters:
| Inner dimensions of the combustion chamber | 700 x 400 x 810mm |
| Material | mirror stainless steel |
| Open area | 25 * 25mm, height: 50mm |
| Burner | burner by the aperture of ¢0.17 mm of nozzle and regulating valve, and is equipped with four ¢the air inlet hole 4 mm, 45 ° Angle |
| Flame height | 20±2mm, high-pressure electron ignition |
| Gas | propane gas with 95% purity (provided by the user) |
| Sample clamps | two u-shaped stainless steel frames, 15mm wide and 5.0mm thick |
| Timer | 0~99.99S/M/H can be set |
Main features:
1. The box body of the test device is made of stainless steel plate
(table 1.5mm)
2. Designed and manufactured with all stainless steel materials,
and has six moving parts: (1)Y moving (2) X moving (3) Z moving (4)
Y sliding (5) rotating about Z axis (6) the burner around the
x-direction -450~+450.
3. Adopts the manual method to realize the relative movement of X,
Y and Z between the test piece and the burner, as well as the
quadrature rotation around the Z axis, which can easily determine
the relative position between the test piece and the burner
4. Equipped with a positioning switch and beeping and ringing to
facilitate the timing and end of the combustion test.
5. Equipped with manual adjustable damper device. Turn the torque
to the right to open the damper, and reduce the torque.When using
power ventilation, adjust the size of the damper to the air
velocity of the tuyere to be 0.7 ± 0.1m/SEC, and tighten the lock
nut.
