UL94 Vertical Flame Test Chamber Plastic Test Equipment
Description:
The test chamber is widely applied throughout industry, especially
in electrical manufacturing, where it is widely used for the
testing of electrical products. The test measures the burning rate
of samples positioned either horizontally or vertically.
It conforms to all five UL 94 horizontal and vertical burner tests
and associated ASTM international standards.
Standard:
GB/T 2408,GB/T 4610,UL94,ASTM D1929,IEC707
Structures:
1. Test chamber: The front door is equipped with a window and an opaque visor that
can block the window. The bottom of the square box is equipped with
a blasting aluminum foil to prevent overpressure, and the top is
equipped with a pressure regulating device inside the box.
2. Inner dimensions: height 914 ± 3mm, width 914 ± 3mm, depth 610 ±
3mm;
3. Outer dimensions: height 1680mm, width 1450mm, depth 850mm (this
size is for reference only)
4. Material: 1.5mm steel plate, baking white rice electrostatic paint,
black paint inside
5. Photoelectric measurement system:
5.1 Light source: 6.5V incandescent lamp, light wavelength 400~750nm.
5.2 Receiver: Silicon photocell, the light transmittance is 0% for no
light, and the light transmittance is 100% without obstruction.
6. Radiation cone:
6.1 Radiation cone: It consists of a heating element with a rated power
of 2600W, which can provide 10KW/m2~50KW/m2 radiation intensity at
the center of the sample surface.
6.2 Radiation cone heater: power supply transformer power 3000W,
independent single-phase isolation transformer temperature
controller, thyristor control
6.3 Heat flow meter: a flat area with a measuring range of 50 kw/m2 and
a receiving radiation area of 10 mm, with water cooling
6.4 Smoke Density Flammability Test apparatus Igniter: The igniter nozzle is made of Φ4.0mm aperture copper tube,
and the flame length and horizontal measurement are 30mm.
7. Combustion system: consists of a pressure regulating valve, a
filter, a regulating valve flow meter, and a burner.
7.1 Gas is propane with a purity of 95% or more
7.2 Burner: consists of an igniter and a nozzle. The nozzle is at a
horizontal position 10 mm above the upper surface of the specimen
and placed at the center of the specimen.
