F150A Flame Spread Tester Operation Steps

F150A flame spread tester is a test equipment independently developed and produced by our company Qisnun Precision Electromechanical Technology Co., Ltd. It offers high performance and comprehensive after-sales service. It is suitable for single-component or multi-component applications (coating, sewing, multi-layers). Determination of vertical flame propagation properties of clothing, films, curtains, valances and large tents, including pergolas and door covers, for clothing, films, laminates. similar products and combinations, used to evaluate the flame spread of materials or combinations of materials after exposure to flame under controlled laboratory conditions.

Applicable standards:

GB/T 5456-2009 Determination of flame propagation performance of vertical specimens for combustion properties of textiles

ISO 6941:2003

ISO 15025

Technical parameters:

1. Ignition timing: 0-99.99 seconds can be set at will.

2. Afterburning time, slow burning Time and flame spread timer: 0 ~ 99.99 seconds, accuracy: ± 0.01 seconds.

3. Flame height: adjustable from 10 to 60 mm.

4. Flame height measuring device: ruler height 40 mm.

5. Sample holder: rectangular frame with a height of 560 mm.

6. Gas used: industrial propane or butane gas.

7. Sample size: 560mm × 170mm.

Operation steps:

First: prepare the accessories and test the samples;

Open the heat-resistant glass observation window;

Turn on the power switch of the instrument to enter the LCD operation interface;

Turn on the light and exhaust switches;

Wrap the cotton flossn around the three fixing brackets;

Hang the clamp containing the sample on the sample holder and fix it;

Align the three cotton filaments on the balance. marks and pass them through the lead ring;

At the other end of the line, hang a weight and hook it to the three sensors;

Set the number, ignition time and other parameters on the LCD screen;

click [Ignition];

The torch lights;

Flame size can be adjusted via the button on the dashboard;

Position the torch according to the angle of the test requirements Pour;

Push the torch along the track;

The sample is ignited;

When it reaches the first mark, the cotton thread burns and the weight falls. on the sensor;

Get the mark 1 time;

When it reaches the second scale, the cotton thread burns and the weight falls on the sensor;

Leave the mark 2 fois;

When burning until the third time. When descaling, the cotton thread burns and the weight falls on the sensor;

Get the mark 3 times;

Press the timer button on the panel and observe the ignition of the sample;

p>

The flame goes out, the timer ends and the value is obtained;

Click [Print] to get the test data;

Save and you can view the data;

Based on the data obtained during the test, analysis and comparison are carried out to evaluate the fire propagation performance of the material.
