All flame retardant products, fabrics, leatherette, skai and foams
Flame retardant products, fabrics, leatherette or foams, are resistant to combustion according to a classification established to define their reaction to fire.
This fire classification is segmented into 5 categories M0, M1, M2, M3 and M4 ranging from the most flammable, M0, to the most easily flammable, M4.
This classification is established by laboratories approved by the Ministry of the Interior, including CSTB.
Combustibility is the amount of heat emitted by complete combustion of the material while flammability is the amount of flammable gas emitted by the material.
