FURNITURE CALORIMETER ISO/ BS EN 16989

The Calorimetry for complete seats used in railways provides a means of  determining the burning behavior of a rail vehicle seat design using a set of complete seats prepared and tested according to the procedures. It also sets out a standardized procedure to assess a seat’s potential for vandalization. The test seats are subjected to a 15kw propane-flued ignition source under an exhaust hood with a well-ventilated condition. The  measurement to be made include the heat release rate (HRR), maximum average heat release (MARHE), total smoke production (TSP), and flame height.

Features & Technical Specifications

 MODEL- DNG-FC-01

Exhaust Hood and Duct 

  • A stainless steel made hood is installed above the floor, size is 3 meters by 3 meters. 
  • The hood is used to collect the combustion gas and transfer to the exhaust pipe by the plenum chamber on the top. 
  • The side skirt is installed underneath the edge of hood to improve smoke capture, made of glass-fiber cloth, resistant to temperatures up to 1100°C.
  • The exhaust pipe is 400mm in diameter and 12 times diameter in length.
  • The hood and duct are connected to the exhaust system that capacity not less than 12,000 m3/h. 

Instrumental Section 

  • The instrumental section is installed at the end of the exhaust duct, equipped with thermocouples, differential pressure transducer, sampling probe, and white light system. 
  • The flow sensors used in the exhaust duct re a bi-directional probe, the probes are made of 316 stainless steel. 
  • The pressure transducer with a range of at least (0-200) Pa and an accuracy of ±2 Pa. Response time of 90% of the output of the pressure transducer is not more than 1s. 
  • Equips 3 K type thermocouples for temperature Measurement, 24 AWG wire gage, measurement range up to 1000 degrees, with an accuracy of ±0.75%. 
  • White light measuring system, consists of a lamp, plano-convex lenses, aperture, and photocell. 
  • The smoke measurement system is mounted on the integrated measuring section using a flexible joint diametrically opposite each other. 
  • Bar type sampling probe, SS304 made, removable design for easy removal of particles build-up in the sampling probe, reducing system delay time.

Gas Sampling System 

  • Three stages particle filters, 1st: Soot filter, glass fiber cotton, filtering large  particles in the combustion gas; 2nd: PTFE filter, filtering rate up to 2 microns; 3rd: PTFE membrane, filtering rateup to 0.5 microns, effective  moisture isolation. 
  • Compressor cold trap, cool capacity up to 320KJ/h, temperature control  accuracy up to 0.1 °C, static variation 0.1 °C, self-starting and maintenance free. 
  • Steamtrap, automatic drainage ofthe coolingwater generated by the cold trap, maintenance-free. 
  • Dry the residual moisture in the sampling gas, with quick disassembly and  replacement of the drying medium. 
  • Vacuum sampling pump with a sampling capacity of 16 L/min, continuous sampling pressure of 50KPa, high gas tightness, low noise and low vibration. 

Gas Analysis System 

  • Paramagnetic type O2 analyzer, measurement range of 0 to 25%, accuracy of ± 0.01%. 
  • NDIR type CO2 analyzer, measurement range of 0 to 10%, accuracy of ± 0.01%. 

Gas Burner Assembly 

  • Stainless steel made burner assembly, the burner can be moved and adjusted the loading force. 
  • Remote-controlled ignition device, pilot flame ignition with sparker.
  • Mass flow controller for flame source control, accuracy up to ±2%.
  • Auto flow control software, gas supply flow rate at 324±5mg/s. 

Calibration System 

  • Sandbox burner, provides an even gas flow over the top. 
  • Remote-controlled ignition device, pilot flame ignition withsparker. 
  • Mass flow controller for flame source control, accuracy up to ±2%.
  • Auto flow control software
