Flame Spread Tester Operation

 

　　1.Have a strong after-sales service team;

 

　　2.Able to handle various issues in a timely and fast manner,relieving customers of any worries they may have;

 

　　3.Complete spare parts to solve the problem of long lead times when ordering spare parts;

 

　　4.Keep up with industry standards updates and provide textile testing instruments that meet the new standards in a timely manner.

 

　　F150 Flame Spread Tester is suitable for measuring the vertical flame spread performance of single or multi-component clothing,films,curtains and curtains,as well as large tents including pergolas and door covers(coatings,seams,multi-layer,sandwich products,and similar combinations).It is used to evaluate the performance of materials or material combinations in contact with flames under controlled laboratory conditions.

 

　　Applicable standards:

 

　　GB/T 5456-2009 Textiles-Determination of flame propagation performance of vertically oriented specimens

 

　　ISO 6941:2003

 

　　ISO 15025

 

　　Technical parameters:

 

　　1.Igniter timing:0 to 99.99 seconds can be set arbitrarily.

 

　　2.Continuation time,smoldering time,and flame spread time timers:0-99.99 seconds,accuracy:±0.01 seconds.

 

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

 

　　4.Flame height measuring device:The ruler has a height of 40mm.

 

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

 

　　6.Gas used:Industrial propane or butane gas.

 

　　7.Sample size:560mm×170mm.

 

　　Operation:

 

　　1.Firstly,prepare the accessories and test samples;

 

　　2.Open the heat-resistant glass observation window;

 

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

 

　　4.Turn on the lighting and exhaust switches;

 

　　5.Wrap the cotton thread around three fixed brackets;

 

　　6.Hang the fixture containing the sample onto the sample holder and secure it;

 

　　7.Align the three cotton threads with the scale marks and thread them through the lead ring;

 

　　8.On the other end of the line,hang a weight and hang it vertically above the three sensors;

 

　　9.Set parameters such as number and ignition time on the LCD screen;

 

　　10.Click on【Ignite】;

 

　　11.The spray lamp lights up;

 

　　12.The flame size can be adjusted through the knob on the instrument panel;

 

　　13.Fold down the spray lamp according to the angle required for testing;

 

　　14.Push the spray lamp along the track;

 

　　15.The sample is ignited;

 

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

 

　　17.Obtain the time of marker 1;

 

　　18.When it reaches the second mark,the cotton thread burns and the weight falls onto the sensor;

 

　　19.Obtain marker 2 time;

 

　　20.When it reaches the third mark,the cotton thread burns and the weight falls onto the sensor;

 

　　21.Obtain marker 3 time;

 

　　22.Press the timer button on the lower panel to observe the ignition of the sample;

 

　　23.The flame goes out,the timing ends,and the numerical value is obtained;

 

　　24.Click[Print]to obtain test data;

 

　　25.Save to view data;

 

　　26.Analyze and compare the data obtained from testing to evaluate the fire spread performance of the material.
