Commonly used flame retardant performance testing methods for flame retardant fabrics include combustion test method and extreme oxygen index method. Among them, the combustion test method is also divided into vertical method, 45° tilt method and horizontal method. Different test methods are used for different flame retardant fabrics.
The vertical method stipulates that the sample is placed vertically, and the combustion source ignites the sample below the sample. The minimum ignition time, afterburning time, flame retardant time, flame spread speed, damage length, Damage area and other indicators related to flame retardant performance. The vertical burning method is mainly used for flame retardant testing of clothing textiles, curtains and other fabrics.
The 45° tilt method stipulates that the sample is placed at a 45° tilt. The combustion source ignites the sample on the upper or lower surface below the sample. The time required for the sample to burn upward for a certain distance is measured, or the afterburning after the sample is burned is measured. , flame retardant time, flame spread speed, charring length, charring area, or the number of times the sample needs to be exposed to the flame when burning to a certain distance from the lower end of the sample, etc., and other indications related to flame retardant performance. The 45° tilt method is mainly used for flame retardant testing of carpets and other fabrics.
The horizontal method stipulates that the sample is placed horizontally, ignited at the head end of the sample, the distance the flame spreads on the sample and the time it takes to spread this distance are measured, the burning rate is calculated, and the burning rate is used to characterize it. Fabric flame retardancy. The horizontal method is mainly used for flame retardant testing of automotive interior decoration materials.
