Retardant overalls fabric three key indicators

I. smoldering time less than 2 seconds : the specified test conditions, when the termination of combustion with flame , or removed ( point ) after the fire continuing flameless combustion material in less than 2 seconds.

Second, the continued burning time of less than two seconds : the specified test conditions, remove the ( dot ) continued after the fire source material flame burning time of less than two seconds .

Third, the length of the combustion loss , also known as carbon long. At a specified test conditions, material damaged area in a predetermined direction is less than the maximum length 50CM.

Ie, after the Flame resistant overalls Fabric finishing by the method specified in contact with the flame a certain time , and then remove the flame , flaming combustion continued determination fabric of time and flameless combustion of the time, as well as fire-retardant overalls fabrics were damaged degree . Flaming combustion time and flameless combustion shorter the time , the lower the degree of damage , then flame retardant fabric fire retardant overalls better ; On the contrary, it means that poor flame retardant fabrics .
