　　G233 Vertical Combustion Tester is suitable for measuring the flame retardancy,flame retardancy,and carbonization tendency of medical clothing,clothing fabrics,decorative fabrics,tent fabrics,and other textiles with flame retardancy requirements.

　　Applicable standards:

　　GB/T 5455-1997,GB/T 5725-2009,CAPI 84,ASTM D6413,ISO 1210-1996

　　Main parameters:

　　1.Sample size:80mm×300mm;

　　2.Ignition mode:automatic;

　　3.Ignition time:12 seconds;

　　4.Igniter caliber:Φ11mm;

　　5.Continuation and smoldering time:0-999.9 seconds;

　　6.Flame height:40mm high;

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

　　8.Working power supply:AC220V,50Hz.

　　Operation:

　　1.Firstly,prepare the accessories and test samples;

　　2.Fix the prepared sample onto the sample fixture;

　　3.Open the instrument safety door;

　　4.Turn on the gas switch and ignite the ignition tube;

　　5.Adjust the flame size through the knob;

　　6.Fix the fixture containing the sample onto the sample holder;

　　7.Close the instrument safety door;

　　8.Press the automatic mode,and the ignition tube will ignite the main flame tube;

　　9.The sample is ignited(after 12 seconds,the main flame tube automatically goes out);

　　10.Start timing and record the reignition time;

　　11.The ignition time has ended and the ignition time has started;

　　12.The smoldering timer is over;

　　13.Record the reignition and smoldering times and reset them to zero for the next test;

　　14.In the instrument test,record the smoldering and reignition time,and the results can be used to evaluate the flame propagation speed and damage length of the material after being ignited in a vertical state,in order to evaluate the combustion performance of the material.
