Test equipment used to determine the flammability of solid specimens under set conditions of oxidation environments.
Simple calculations result in the Combustion Rate based on the speed at which the flame front advances on the specimen surface within a set time.
Used for approval of organic materials for the Automotive Transportation Industry where flammable, organic materials that may come into contact with passengers during a crash must meet specific requirements.
Designed to meet ISO 3795, ASTM D 5132, DIN 75200 and other equivalent standards.

Applications:

This method is applied to inflammable materials used in the Automotive Industry, in passengers cars, trucks and buses such as: seat cushions, seat backs, seat belts, headlining, convertible tops, arm rests, all trim panels including door, front, rear and side panels, compartment shelves, head restraints, floor coverings, sun visors, curtains, shades, wheel housing covers engine compartment covers, mattress covers, and any other interior materials including padding and crash-deployed elements, that are designed to absorb energy on contact by occupants in the event of a crash.

This apparatus simulates, under determined conditions of oxidation the flammability of a solid specimen. By calculation the combustion rate is obtainable. This is referred to the speed at which a flame front is transmitted across the specimen’s surface in a specified time. Omologation and acceptance of material of organic origin, in passengers cars, trucks and buses depends on these not presenting a rapid transmission of flame front (flashing) referred to speed “X mm/ min.”.

The test specimen is inserted into the test cabinet (for the determination) on a support and in a horizontal position and its free end exposed to a flame for a predetermined time (15”). To avoid draughts and that these influence combustion, the test unit is hosed in a cabinet of a determined size with suitable air inlets.
