Operation steps of G233 vertical flammability tester

The G233 vertical flammability tester is a test equipment independently developed and produced by our company qisnun Precision Electromechanical Technology Co., Ltd. It is suitable for flame retardant and flame retardant textiles such as medical clothing, clothing fabrics, decorative fabrics and tent fabrics which have flame retardant requirements. and determining the flame retardant performance of carbonization tendency.

Applicable standards:

　7. Gas used: propane or butane or petroleum liquefied gas;

　8. Operating power supply: AC220V, 50Hz.

　Operation steps:

First: prepare the accessories and test the samples;

Attach the prepared sample to the sample holder;

Open the safety door of the instrument;

Turn on the gas switch and light the fire tube;

Use the knob to adjust the flame size;

p>

Attach the holder containing the sample to the sample holder;

Close the safety door of the instrument;

Press the automatic mode and the pilot tube ignites the main flame tube;

The sample is ignited (the flame tubemain turns on automatically after 12 seconds of switching off);

Start timing and record afterburner time;

Start timer \'burnout End, start counting the slow burn time;

The smoldering timer ends;

After recording the afterburning and smoldering time, [clear] for the next time

During the instrument test, the smoldering and afterburning times are recorded. The results can be used to assess the speed of flame propagation and damage to the material after it is ignited in the vertical state. length to evaluate the combustion properties of materials.
