Introduction:
Smoke Box (NBS Fire Tester Smoke Density Chamber For Plastic) measures optical density of smoke generated from test sample when test sample of certain thickness is exposed to heat source(2.5W/cm2, 2KW/m2 using by ASTM E 662 furnace) or fire in a chamber.
Using ISO 5659 conical radiant heat furnace, we can change the heating condition from 10KW/m2 to 5KW/m2 or 70kW/m2 according to different requirements.
ASTM E 662: Standard Test Method for Specific Optical Density of Smoke Generated by Solid Materials
ISO 5659-2: Plastics-Smoke generation -Part 2: Determination of optical density by a single-chamber test

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.
