NBS Flammability Analyzer Smoke Density Chamber For Plastic
Smoke Box (NBS Flammability Analyzer Smoke Density Chamber For Plastic) measures the optical density of smoke generated from a test sample when a test sample of a certain thickness is exposed to a heat source(2.5W/cm2, 2KW/m2 using ASTM E 662 furnace) or fire in a chamber.
NBS Flammability Analyzer Smoke Density Chamber For Plastic is satisfied with standards ASTM E 662, BS6401, ISO 5659, NES 711, NEPA 258, etc.
Using an ISO 5659 conical radiant heat furnace, we can change the heating condition from 10 kW/m2 to 50 kW/m2 or 70 kW/m2 according to different requirements.
Standard:
• 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
• NES 711: Determination of the Smoke Index of Products of Combustion from Small Specimens of Material.
The inner dimensions of the chamber are 914mm±3mm long, 914mm±3mm high, and 610mm±3mm deep.
The inner surface consists of a Teflon coating, which is resistant to chemical attack and corrosion and easily cleaned.
Test chamber with full-width opening door, allowing easy access for sample loading and chamber cleaning.
Provided a hinged front-mounted door with an observation window and a removed opaque door cover to the window to prevent light from entering the chamber.
Chamber walls are pre-heated for easier start-up and convenient equipment operation.
Safety blow-out panel, easily replaceable, allows for the safe operation of the test method.
Two optical windows, each with a diameter of 75mm, are mounted at the top and bottom of the cabinet.
The light measuring system consists of an Incandescent lamp and a photomultiplier tube.
Provided a range-extension filter in the light path, adjusting the accuracy of the instrument on any scale.
Conical Heater - is wound in the form of a truncated cone, rated 2600 W at 230 V with a heat output of 50 kW/m2.
Auto Split Shutter automatically opened to transmit radiation to the sample, and Spark Igniter to ignite the sample.
Heat Flux Meter - for setting the irradiance level at the surface of the specimens, the range is from 0- 100 kW/m2.
Furnace Heater, rated 550W at 110 V with a heat output of 25 kW/m2.
The movement of the sample is controlled by an air cylinder automatically.
Air-cooled calorimeter for setting the irradiance level at the surface of the specimens.
Provided with no pilot flame and pilot flame modes. The digital display flow rate of air and propane.
Gas measurement ports are provided for optional measurements of toxic gases.
19 analysis racks, 15 touchscreen panel-type PC for the whole control, and automatic testing.
DAQ(Data Acquisition) Program is controllable with the touch screen panel PC.
Testing results: Light transmission, Optical density, Mass optical density(MOD), Mass loss rate, the Clear-beam correction factor, etc.
