Model:NBS
Use:The Smoke Density Chamber has been established for many years and is used widely in all industrial sectors for the determination of smoke generated by solid materials and assemblies mounted in the vertical position within a closed chamber.
Standard:ASTM E662, ASTM F814, NFPA 258, BS 6401, GB/T 8323. Options:ISO 5659/IMO FTPC Part 2, ATS 1000.001/ABD0031, NES 711
Description
The Smoke Density Chamber has been established for many years and is used widely in all industrial sectors for the determination of smoke generated by solid materials and assemblies mounted in the vertical position within a closed chamber.
This widely-used test instrument measures the specific optical density of smoke generated by materials when an essentially flat specimen, up to 25 mm thick, is exposed vertically to a radiant heat source of 25 kW/m2, in a closed chamber, with or without the use of a pilot flame.
Test chamber with full width opening door, allowing easy access for sample loading and chamber cleaning
Controls are mounted beside chamber for convenient operation. They are not obstructed when door is open
Smoke density and temperature are on digital displays, for easier use and greater accuracy
Chamber walls are pre-heated for easier start-up and convenient equipment operation
Safety blow-out panel, easily replaceable, allows for safe operation of test method
Gas measurement ports are provided, for optional measurements of toxic gases
Cabinet designed with a standard 19" rack, for simple addition of gas analysers and chart recorder and other control units
Computer software
The FTT Smoke Density Chamber has been designed specifically for potential modification to incorporate the ISO 5659 Conical Radiant Furnace which extends the potential of the Smoke Chamber by allowing variable heat fluxes (up to 50 kW/m2), horizontal orientation of the specimen and the measurement of mass loss rate of the specimen. This also conforms with the recent IMO test protocols.
