FMVSS 302 Automotive Materials Horizontal Combustion Tester For Motor Vehicle Interiors
FMVSS 302 Automotive Materials Horizontal Combustion Tester Introduction:
This test equipment is designed and manufactured according to the relevant provisions of FMVSS 302 and ISO3795 standards. It is suitable for the horizontal combustion test of interior materials of automobiles (sedans, multi-purpose passenger vehicles, trucks and buses). The automobile interior material combustion tester is composed of the test part and the control part, and adopts an integrated design, which is convenient for on-site installation and commissioning. The control system has a high degree of automation and has an automatic ignition function. The temperature and time are digitally displayed, which is convenient for observation and recording, and is stable and reliable to use.

FMVSS 302 Automotive Materials Horizontal Combustion Tester Test principle and parameters:
The test adopts the horizontal combustion method, using a Bunsen burner to generate a constant flame (height 38mm) to ignite a horizontally fixed sample, and measure the relationship between the flame spread distance and time. Key parameters include:
1. Flame application time: 15 seconds standard burning time
2. Burning rate calculation: calculated based on the time difference between the flame front passing the 100mm and 200mm marks
3. Self-extinguishing characteristic evaluation: record the continuous burning time after the flame leaves the sample

FMVSS 302 Automotive Materials Horizontal Combustion Tester result determination and grading standards:
1. Qualified determination:
- Average burning rate ≤102mm/min
- Any sample can be directly judged as qualified when the burning distance does not exceed 51mm (2 inches)
2. Grading extension (some manufacturers adopt higher standards):
- Grade A: Burning rate ≤50mm/min (aviation material standard)
- Grade B: 51-100mm/min (mainstream automobile qualified line)
- Grade C: >102mm/min (unqualified material)
