NBS Plastic Smoke Density Test Apparatus ASTM E 662 Standard flammability test equipment
the heat flux in the box can be as high as 50 kw / m2, and the sample can be positioned laterally to test the sample mass loss rate. This is also in line with the latest mo test terms. Measure the density of the smoke cloud when the sampe is measured with or without a forward flame in a
confined space and exposed to a radioactive heat source at 25 kW/m2 vertically. With the lSO 5659 radiant heating furnace. users can
arbitrarily adiust the heatina conditions from 10 kW/m2to 50kW/m2 or70kW/m2
The main principle of smoke density measurement is that in a specific space, cables or materials generate smoke under specific burning on
radiating conditions. and the beam will decay after passing throuah the smoke. Measure the liaht transmittance of the beam and calculate the
specific optical density And smoke density
Cabinet structure:
1. The test box consists of a box, a sample box, a radiation cone, an igniter, a light transmission and measurement device and other related
control devices.
2. Ergonomic structure desian and control desian; the box body adopts the desian method of full open door; the door lock desian is convenient to
close the box door at one time, optimize the operation process.
3. The test box door can be fully opened, which is convenient for loading and unloading samples and cleaning the box.
4. The front door school mallet is installed. equipped with a window and a movable opaque light shielding plate that can block the window to
prevent light from entering the sealed box.
5.the controller is located on the side of the box for easy operation.When the door is closed it does not affect the viewina controler
6. Safety flameout board, easy to replace, safer operation
7. Gas measurement port can be provided for testing gas toxicity
8.The coating of the test box is easy to clean and resistant to chemical corrosion
Burning device:
1.Heating vertebra: Power 2600W, input temperature range 0~1000℃.stable within+2 ℃ within 50 minutes, and can provide radiance of
10KW/m2-50KW/m2
2 sing a mass flow controller and a differential pressure sensor can improve the accuracy of the manometer and achieve automatic leak
testing.
3. The igniter is equipped with an automatic ignition device; the flame length is 30mm±5mm. According to the standard, the blue flame has a
yellow top.
Smoke density measurement system
1.the smoke density and temperature are displaved diaitaly. which makes it easier to view and more accurate
2. Photoelectric detection components include photomultiplier tubes. maanifying filters, shutters, filters, neutral filters, lenses, and optical
windows.
3.The light source is a 6.5V incandescent light source
4. The top of the box is installed with an ootical cassette. the liaht source is a side window tvpe photomultiolier the transmission accuracy car
reach 0.001%5
5.Achromatic lens
6.Silicon photo cell
7. High gain low noise amplifier control circuit
Control System
1.Automatically complete the test various signals are automatically collected
2.Brand computers
3. The printer is optional.
4.Voltage: 220V power 4KW
5. The propane gas shall be prepared by the customer.
