Automotive Interior Material Vertical Combustion Tester
Category：Flammability Tester
Introduction
The Automotive Interior Vertical Flame Test Apparatus is specially designed for evaluating the vertical flame characteristics of automotive interior materials in compliance with national standard GB 32086-2015. It is suitable for M3-class vehicles carrying more than 22 passengers, specifically for interior curtains, sunshades, and other hanging materials. The apparatus provides precise, repeatable measurements to ensure materials meet stringent fire safety requirements. This equipment is not suitable for buses with standing passengers.
Application
This instrument is widely used in the automotive industry to assess the fire safety of interior hanging materials. Typical applications include:
Automotive interior safety testing
Evaluates the vertical flame spread of curtains, sunshades, and decorative hanging materials in M3-class passenger vehicles.
Quality control for interior components
Ensures all batches of interior materials meet national flame-retardant requirements before vehicle assembly.
Material development and certification
Assists manufacturers in developing new fabrics and composites with enhanced vertical flame resistance.
Regulatory compliance testing
Supports automotive OEMs in fulfilling GB 32086-2015 and European Union directives related to fire safety of specific interior materials.
Standards
Design Standard: GB 32086-2015 – Vertical flame characteristics of specific automotive interior materials
Other Standards: EU Automotive Directive 95/28/EC – Vertical flame testing of interior materials

FAQ
1. What materials can be tested with this apparatus?
Hanging interior fabrics, curtains, and sunshades used in M3-class passenger vehicles. It is not suitable for standing passenger buses.
2. Can the flame angle and height be adjusted?
Yes, the default flame angle is 30°, with an optional 45° setting. Flame height is continuously adjustable between 10 mm and 100 mm.
3. How is timing controlled?
Flame application and after-flame durations are automatically timed with a resolution of 0.1 s, and all data can be recorded via the touchscreen interface.
4. What type of gas is required?
Industrial propane, butane, or liquefied petroleum gas can be used. Gas supply and connections must be provided by the user.
5. Can I observe the sample during the test?
Yes, the sample is fixed on a front-facing fixture aligned with the viewing window, allowing clear observation of flame behavior during testing.
