The standard used to judge the performance of the fire retardant fabric
is rate of combustion of the fabric. Namely burning the fire retardant fabric in accordance with the provisions of the method for some time, and then remove the flame to determine the afterglow and after flame time, and the extent of damage to the fabric. The shorter the afterglow and after flame time, the lower the degree of damage, this can show the fabric's fire retardant performance is better; otherwise, it means that the fabric's flame retardant performance is poor.
There are different testing method for the fire retardant fabric due to the different principle, equipment and purpose. The test results of the various test methods are difficult to compare with each other. The experimental results can only explain the combustion performance of the sample to a certain extent. The combustion experiment method is mainly used to test the burning breadth (carbonized area and damage length), the burning time and the smoldering time. So Europe and the United States have the corresponding fire retardant test standards, the standard has a detailed requirement, customers buy fire retardant fabrics, whether to achieve the European and American flame retardant standards is to determine the quality of fabric conditions.
