FMVSS 302 Flammability of Automotive Materials
Compliance
FMVSS 302 (49 CFR 571.302), ISO 3795, SAE J369, ASTM D 5132, FAR Part 25 Appendix F Part I, Airbus AITM 2.0003, Boeing BSS 7230.
The FMVSS 302 Flammability of Automotive Materials Tester, in accordance with FMVSS 302 (ISO 3795, DIN 75200), is designed to evaluate the burn resistance performance of the interior materials used in the occupant compartments of motor vehicles.
During the FMVSS 302/ISO 3795 test, the specimen is mounted on the U-shape specimen holder, the specimen is inserted horizontally into the test chamber, and a 38mm height flame is applied to the specimen for 15 seconds. The flame spread time and distance are recorded to calculate the material's horizontal burning rate.
FMVSS 302 Flammability of Automotive Materials Tester consists of:
The test chamber is made of stainless steel with a wall thickness of 2mm, which is not easily deformed during the combustion test.
The chamber is equipped with a toughened glass transparent viewing window which allows easy observation by the engineer.
Ten 19mm ventilation holes in the bottom of the chamber with 13mm wide ventilation slots all around.
Provides a bunsen burner and a precise valve to adjust flame height to 38mm.
Provides an ISO 3795 standard φ9.5mm burning tube and an FMVSS 302 standard φ10mm burning tube, the burning tube can be fast exchanged.
A stainless steel made collection tray for molten drips at the bottom of the chamber.
A U-shaped stainless steel specimen holder that can be inserted smoothly from the right side of the chamber.
The timer can be automatically activated after the specimen holder is inserted.
The application flame can be automatically cut off after the start of the test.
