LFY-602A Large 45° Fabric Flame Resistance Testing Instrument

Main purpose 
Method A is used to measure the damaged area and length of textiles and other materials when they are burned at a 45-degree angle. Method B is used to determine the number of times textiles come into contact with flames when they are subjected to thermal melting up to a specified length at a 45-degree angle.
