China Imo Flame Spread Apparatus, ISO5658-2, Find details about China ASTM E1317, ISO5658-2 Tester from Imo Flame Spread Apparatus, ISO5658-2
The MO thermal radiation flame propagation tester is used for the combustion characteristics of building materials, high-speed train materials and ship materials. It measures the spread speed and ignition heat and total heat release of flames according to the distance and CEF (critical heat radiation flow).
This test method is used to evaluate the combustion characteristics of vertically mounted test objects according to ISO 5658-2 and IMO res.653.It also meets the GB/T 28752-2012 flame transverse spread test method on the vertical surface.The test object is exposed to the appropriate heat dissipation area given by the gas combustion type of the heat dissipation panel, and the calibrated thermocouple is used to measure its signal value in mV when the combustion occurs.In addition, the ignition time and flame burning time of the measured object are recorded according to the distance of the tested object, and the flame spreading speed is also recorded.Other test items include ignition heat (MJ/m2), heat from sustained combustion (MJ/m2), critical heat radiation flow (kW/m2), average heat from sustained combustion and total heat loss (kW).
