Operation steps:
First: prepare the accessories and test samples;
Open the heat-resistant glass observation window;
Turn on the instrument power switch to enter the LCD screen operation interface;
Turn on the lighting and exhaust switches;
Wrap the cotton thread around three fixed racks;
Hang the fixture with the sample on the sample rack and fix it;
Align the three cotton threads with the scale marks and pass them through the lead ring;
Hang the weights on the other end of the line and hang them on the three sensors;
Set the number, ignition time, and other parameters on the LCD screen;
Click [Ignition];
Light up the blowtorch;
The flame size can be adjusted through the knob on the instrument panel;
Put the blowtorch down at the angle required for the test ;
Push the blowtorch along the track;
The sample is ignited;
When it burns to the first scale, the cotton thread burns off and the weight falls on the sensor;
The time of mark 1 is obtained;
When it burns to the second scale, the cotton thread burns off and the weight falls on the sensor;
The time of mark 2 is obtained;
When it burns to the third scale, the cotton thread burns off and the weight falls on the sensor;
The time of mark 3 is obtained;
Press the timing key on the panel to observe the ignition of the sample;
The flame goes out, the timing ends, and the value is obtained;
Click [Print] to obtain the test data;
Save to view the data;
Analyze and compare the data obtained in the test to evaluate the fire spread performance of the material.
