DX8342 Flammability testing machine for fireproof building
materials
Executive standard: in line with GB/T8626-2007 "Test Methods for Flammability of
Building Materials’
GB/T10801.2-2002"Extruded Polystyrene foam for Heat insulation
(XPS)"
Scope of application: It is mainly applicable to the test method for judging whether
building materials have flammability under specified conditions.
Technical Parameters:
1. The inner size of the combustion box: width 700× depth 400×
height 810mm
2. Material: mirror stainless steel
3. The bottom is a natural vent, and the vent is composed of a
square box.
4. Open area: 25×25mm, height: 50mm
5. Burner: The burner is composed of a nozzle with a hole diameter
of ¢0.17mm and a regulating valve, and is equipped with four air
suction holes of ¢4mm at an angle of 45°.
6. Flame height: 20±2mm, high-voltage electronic ignition,
automatic ignition and reset
7. Gas: propane gas with purity of more than 95% (provided by the
user)
8. Specimen clamp: composed of two U-shaped stainless steel frames,
with a width of 15mm and a thickness of 5.0mm
9. Timer: 0~99.99S/M/H can be set
Conditions of use:
The floor is flat, well ventilated, and free of flammable,
explosive, corrosive gases and dust.
There are no sources of strong electromagnetic radiation in the
vicinity.
Leave proper maintenance space around the equipment.
Temperature: 25°C~35°C.
AC220V/50HZ.
Allowable voltage fluctuation range: 220V±10%.
Allowable frequency fluctuation range: 50Hz±1%.
The user is required to configure the corresponding capacity of air
and gas gas sources for the equipment at the installation site, and
the power supply must be independent and especially designed for
the use of this equipment.
Key features:
1. The box of the test device is bent by stainless steel plate
(δ1.5mm), which has the characteristics of beautiful appearance and
corrosion resistance and anti-aging.
2. This instrument is designed and manufactured with all stainless
steel materials, with six moving parts: (1) Y-direction movement
(2) X-direction movement (3) Z-direction movement (4) Y-direction
sliding (5) rotation around Z-axis (6) burner swing around
X-direction -450~+450.
3. This instrument adopts a manual mode to realize the relative
movement of X, Y and Z between the tested piece and the burner, as
well as the quadruple rotation around the Z axis, which can easily
determine the relative position between the tested piece and the
burner, and realize various test methods specified in
GB/T8626-2007.
4. The instrument is equipped with a positioning switch, plus a
buzzer, which is convenient for the timing and end of the
combustion test.
5. This instrument is equipped with a manual adjustable damper
device, and the twist turns to the right to open the damper, and
vice versa. When power ventilation is used, adjust the size of the
damper to the air flow rate of 0.7+/_0.1 m/s and lock the lock nut.
When natural convection is used, the damper is opened to the
maximum and locked.
