SDB NBS Smoke Optical Density Testing Equipment

Introduction:

• The SDB NBS Smoke Optical Density Testing Equipment has proved to be one of the most versatile fire testing instruments since its inception in the 1980s.

• SDB NBS Smoke Optical Density Testing Equipment is the most widely accepted apparatus for the measurement of smoke from burning materials and measures specific optical density under flaming and non-flaming conditions. It is also used for the extraction of toxic gas.

• SDB NBS Smoke Optical Density Testing 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.
