FMVSS 302 Horizontal Flammability Test Chamber for Automotive Interior Materials Testing

The FMVSS 302 Horizontal Flammability Test Chamber is a professional fire testing system designed to determine the horizontal burning characteristics of materials used inside vehicle occupant compartments. It evaluates the flame propagation behavior of automotive interior materials under controlled laboratory conditions and helps manufacturers ensure compliance with international automotive fire safety standards.

The equipment simulates real-world ignition scenarios by exposing test specimens to a standardized flame source for a specified duration. The burning rate, self-extinguishing characteristics, and flame spread distance are accurately measured to assess material fire resistance performance.

Widely used by automotive manufacturers, component suppliers, research laboratories, certification organizations, and quality control departments, this system provides reliable data for product development and regulatory compliance.

Vehicle interior materials must demonstrate controlled burning behavior to reduce fire hazards and improve passenger safety. The FMVSS 302 test is one of the most widely recognized fire safety requirements in the global automotive industry.

This flammability tester is suitable for evaluating:

• Automotive interior plastics
• Vehicle upholstery materials
• Rubber components
• Polymer sheets
• Insulation materials
• Composite materials
• EV interior materials
• Commercial vehicle cabin materials
• Transportation industry materials

The equipment complies with:

• FMVSS 302
• ISO 3795
• DIN 75200
• ASTM D5132-17
• TL 1010
• GB 8410

Additional customization for other flammability standards is available upon request.

The specimen is mounted horizontally on a dedicated U-shaped support frame. A calibrated burner applies a controlled flame to the free end of the sample for 15 seconds. After flame application, the system measures:

• Burning rate
• Flame spread distance
• Self-extinguishing time
• Total burning duration

The results help determine whether the material satisfies the required fire safety performance criteria.
