IMPORTANCE OF FLAMMABILITY TESTING OF CAR INTERIOR MATERIALS.
Burning tests are essential for assessing the flammability properties of car interiors.
Motor vehicles contain a number of components that can burn if subjected to a large enough ignition source. These include seating, headlining and carpeting. Several test methods have been developed by the motor industry to assess burning behaviour. Materials used within the passenger compartment need to have a degree of burn resistance so that occupants have time to escape the vehicle in the event of a fire.
Safety standards such as FMVSS 302 and ISO 3795 (similar standards) have been developed to help reduce deaths and injuries to occupants caused by vehicle fires, especially those originating in the interior of the vehicle from discarded ci******es and matches.
In some cases manufacturers have also developed their own specifications based on these standards,the ISO standard is generally specified for other markets, although not always as a legal requirement. The standards are not only applicable to passenger cars, but also lorries, trucks and coaches as well as agricultural and forestry vehicles.
The standards cover all materials used in the seating compartment of a vehicle, including such components as seat cushions, seat backs, seat belts, headlining, convertible tops, armrests, all trim panels, compartment shelves, head restraints, floor coverings, sun visors and airbags.
