CE-NBS-SBox-1-923x10241-308x341.jpg NBS Smoke Chamber


The Smoke chamber has proved to be one of the most versatile fire testing instruments since it’s inception in the 1980’s. It’s vertical testing configuration, conforming to BS6401 and ASTM E662, has traditionally been the arrangement used and is shown in the images on this page. This orientation is also used for FAA testing. The more recent horizontal configuration is as shown in one of the thumbnails on the left. The sample is exposed in the horizontal plain by a conical heater. This test method, ISO 5659 Part 2, is widely used in the evaluation of plastics and for products used in marine and railway applications. The recent EN 45545-2 European rolling stock fire testing standard has adopted ISO5659-2 as part of the group of test methods to be used in the railway industry for the certification of products and materials. In addition the smoke chamber can be utilised for toxicity measurements using our toxicity chamber option, which is compliant with methods BSS 7239 and AITM 3.0005.

Specification & Features

  • The most widely accepted apparatus for the measurement of smoke from burning materials.
  • The instrument measures specific optical density under flaming and non-flaming conditions. It is also used for the extraction of toxic gas.
  • The Concept Smoke Chamber incorporates all the necessary features and software needed to complete tests, in as simple, ergonomic and user friendly way as possible.
  • The user can choose the configuration required such that the equipment complies with the mandatory requirements of BS 6401/ASTM E662 or ISO5659-2, or hot swappable between both apparatus specifications.
  • Standard stainless steel chamber with additional corrosion resistant finish.
  • Heated chamber walls.
  • Full size chamber door, including an observation window and covering door.
  • Instrument panel to left of chamber for ease of operation.
  • Fixed irradiance vertical oriented heater (25kW/m²).
  • Vertical photometric optical system using state of the art PMT module (mandatory).
  • Push button/software controlled sample positioning system.
  • Push button/software controlled pneumatic lower vent assembly with high capacity extraction fan to efficiently extract smoke following a test.
  • Push button/software controlled pneumatic upper vent.
  • Multi-tip, multi-angle stainless steel pilot burner.
  • Precise furnace control allowing software controlled furnace calibration.
  • Bespoke radiometer for furnace calibration as per BS6401 and ASTM E662.
  • Easy to replace blow-out panel.
  • Built in ports to take gas sampling tubes.
  • Control and data acquisition system including DAQ hardware, Laptop and extensive  software package.
  • Full operating instruction manual.


Technical Data & Requirements


Electrical: 110V AC 60Hz / 230V AC 50Hz

Ambient Temperature: Operating 10°C to 35°C

Dimensions: 1560mm (W) x 2220mm x (H) x 1060mm (D – incl. laptop)

Gas Supplies: The preferred fuel gas used in the test is a mixture of air & propane.

Propane: The flow needs to be capable of delivering 20ml/min at a
minimum pressure of 5 KPa.

Compressed Air: The flow needs to be capable of delivering
750ml/min at a nominal pressure of 400 Kpa.
This is required to obtain flame stability for testing.
