Description
ISO5659 ASTM E662 Nbs Optical Smoke Density Test Chamber
Introduction:
  • moke Density Test Chamber has proved to be one of the most versatile fire testing instruments since its inception in the 1980s.
  • SDB Nbs Optical Smoke Density Test Chamber is used for measuring specific optical density of the smoke from burning materials under flaming and non-flaming conditions. It is also used for the extraction of toxic gas.
  • This equipment is satisfied with standards (ASTM E 662, BS6401, ISO 5659, NES 711, NEPA 258, etc).
  • Using ISO 5659 conical radiant heat furnace, We can change the heating condition from 10KW/to 5KW/by user.
  • In the test of NES 711, there are non-flaming test and flaming test in test conditions different from ASTM E 662.

Standards:
  • ASTM: ASTM E662
  • ISO: ISO 5659-2
  • IMO: FTPC Part 2
  • NES: NES 711

Application Field:
  • IMO;
  • Rail;
  • Wire&Cable;

Features:
  • The inner dimensions of the chamber is 914mm±3mm long, 914mm±3mm high and 610mm±3mm deep.
  • The inner surface is consist of 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 with a hinged front-mounted door with an observation window and a removed opaque door cover to the window to prevent light entering into the chamber.
  • 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.
  • Two optical windows, each with a diameter of 75mm, mounted in the top and bottom of cabinet.
  • The light measuring system is consist of Incandescent lamp and photomultiplier tube.
  • Provided with range-extension filter in the light path, adjusting the accuracy of instrument under the 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, Spark Igniter to ignite the sample.
  • Heat Flux Meter - for setting the irradiance level at the surface of the specimens, the range from 0-100KW/m2.
  • Furnace Heater, rated 550W at 110 V with a heat output of 25 kW/m2.
  • The movement of sample is controlled by 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. Digital display flow rate of air and propane.
  • Gas measurement ports are provided, for optional measurements of toxic gases.
  • 19 analysis rack, 15 touch screen panel type PC for the whole control and automatic testing.
  • DAQ(Data Acquisition) Program 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.
