FYH822 Flame Spread Tester

INTRODUCTION

APPLICATION: 

The tester is used for the combustion characteristics of various combustible materials, high-speed train materials and ship materials, and measures the flame spreading speed, ignition heat and total heat release according to distance and CEF ( critical heat radiation circulation ).  This test method is used to evaluate the combustion characteristics of vertically installed test objects according to ISO 5658 - 2 ( Combustion Test Reaction - Flame Spread ).  The test object is exposed to an appropriate heat dissipation area given by the combustion type of the heat dissipation plate gas, and then when combustion occurs, the signal value is measured in mV units by using a calibrated thermocouple.  In addition, the ignition time is also recorded, the flame burning time of the tested object is 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 of continuous combustion ( MJ/m2 ), critical heat radiation flow ( kW/m2 ), average heat of continuous combustion and total heat dissipation ( kW ).
