T115 Automotive Interior Material Melting Test Instrument uses an upper radiation heat source to emit 30KW/m2 heat to the sample,causing the release of gas and combustion of the sample to produce molten droplets.This tests the thermal radiation melting drop performance of the car interior material.

　　Compliant with standards:

　　NF P92-505 flame retardant testing standard,EU 95/28/EC fire resistance testing standard for automotive interior materials

　　Operation:

　　1.Firstly,prepare the accessories and test samples;

　　2.Turn on the power switch of the instrument and open the safety door of the instrument;

　　3.Place the cotton wool under the bracket,place the height block on the grid;

　　4.Press the【Up】and【Down】buttons on the panel to make the distance between the sample on the bracket and the radiation surface 30 millimeters;

　　5.Place the sample above the bracket;

　　6.Press the[Lighting]button on the panel to turn on the lighting light;

　　7.Move the electric heater to a location next to it where the radiation cannot reach the sample;

　　8.Then press the【Heating】button;

　　9.Simultaneously adjust the power level by rotating the knob;

　　10.When the temperature rises to a certain level,the radiation lamp is heated to the set temperature;

　　11.Move the electric heater back to the position above the sample;

　　12.Press the【Reset】and【Heating】buttons to start automatic timing;

　　13.If the material melts and deforms,keep the height of the electric heater at a distance of 30 millimeters without moving;

　　14.If the material begins to burn,push the electric heater aside for three seconds;

　　15.Wait for the flame to extinguish before moving back to its original position;

　　16.Repeat the same operation repeatedly,and finally check whether the droplets fall and whether they burn or ignite the cotton wool;

　　17.At the end of the experiment,turn off the instrument and remove the sample for analysis and comparison;

　　18.Evaluate the melting performance of the material based on the sample being irradiated by a specified radiation heat source and the melting state of the sample.
