Imo Spread Flame Apparatus Radiant Panel Flame Spread Tester ISO 5658

Introduction:

IMO spread flame apparatus is used to evaluate combustion characteristics of building materials and ship materials and measures spread rate of flame, flame for ignition by distances, CFE (Critical Flux at Extinguishment) and total heat release. This test method is originated from ISO 5658-2 (Reaction to fire tests-Spread of flame- Part 2 Lateral spread on building products in vertical configuration) and measures combustion characteristics of vertical specimen (155mmX800mm). 
The specimen is exposed to the reasonable radiant heat field and is measured by thermocouple for exhaust gas calibrated through the progress of combustion as unit of mV. 
IMO records the spread rate of flame after this records ignition and extinguishment time of flame for each distance of specimens. And the other test results is Heat for ignition (MJ/), Heat for sustained burning (MJ/), Critical flux at extinguishment (kW/), Average heat for sustained burning (MJ/), Total heat release (kW) and so on

International standards:

1. GBT28752
2. ISO5658
3. ASTM E1317
4. IMO Resolution A. 653(16)

Features:

1. All control systems are explosion-proof. 

2. Air Cylinder type of Pilot Flame Burner allowing the flame impingement test method based on IMO to be automatically performed. 

3. Double grid to see spread of flame length as well as enlarged Restrict View Mirror for easy observation. 

4. DAQ Program for applying spread of flame length and combustion characteristics to image storage. 

5. 19" Analysis Rack for measuring spread rate of flame, critical flux, and heat release rate. 

6. IMO Program available of controlling Air Blower to facilitate change in amount of combustion-heat in Radiant Panel Calibration (for measuring heat release rate by each section of radiant panel. 

7. Program for blocking gas supply in failure of ignition in radiant panel, in which Flame Relay System detects
