27 Metre Cube Smoke Density Apparatus-

3 Cubic Meter Smoke Density3 Meter cube DNG

Description

The Smoke Density Chamber provides a test method for measuring the density of smoke generated from building material or cable burning under a defined fire source.

During the test, when smoke is generated, the optical transmittance is continuously changed by blocking the light path through the smoke, resulting in a minimum transmission value and a test time to reach the minimum transmission.

Compliance : 

IS 10810 (Part 63): 1993, Reaffirmed Year : 2019 of IS 17048, IS 17505 (Part 1): 2021 and IEC 61034-1:2005

Features :

  • The internal dimensions of the test chamber are 3000mm*3000mm*3000mm, with a total internal volume of 27 cube metre with inside color: matt black.
  • Internal Material: Stainless Steel (14SWG) fixed into steel angle frame.
  • The test chamber has a door and observation window to allow the user to observe the state of affairs in the combustion chamber.
  • The test chamber shall have several ventilation holes near the floor to ensure a balanced atmospheric pressure inside and outside the chamber.
  • On the left/right side wall of the test chamber, transparent glass panels are installed, with light sources and optical receivers on each side.
  • Provides a floor-mounted fan to evenly agitate the smoke in the combustion chamber.
  • Provides an exhaust fan on top of the chamber to remove the smoke generated by the test.
  • Provides a combustion test stand and a stainless steel alcohol tray. The light source is an imported light source, it is controlled by a constant current source, provides more stable and reliable data compared to the constant voltage mode.
  • Automatically obtain the optical of the grade, with an accuracy of 0.01%.
  • Matching error: F1 not more than 4%, with a linear accuracy of 1%.
  • The imported silicon photocell, equipped with cosine calibration device as well as color filter, by which measure there can be a higher human eye matching.
  • A high-speed data acquisition system, integrating data acquisition, amplification, filtering, conversion, and
    recording.
  • Window based operation software, English version.
  • Laptop computer.
  • Automatic ignition system from outside of chamber
  • Automatic timing and timing reminder in control system
  • All necessary accessories will be provided by us at the time of delivery of equipment.
