SDB ASTM E662 ISO5659 NBS Smoke Density Chamber

Introduction:

• The Smoke Chamber has proved to be one of the most versatile fire-testing instruments since its inception in the 1980s.
• SDB Smoke Density Chamber is used for measuring the 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 the user.
• In the test of NES 711, there are non-flaming tests and flaming tests 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 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 with a 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, and 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 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. 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 PCs 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.
