Two phrases get used interchangeably in aviation upholstery, and the mix-up causes real headaches when the airplane’s apart and someone wants paperwork. Let’s separate them.
The burn test is the lab procedure
The burn test is the physical flammability test — the vertical flame test behind FAR 25.853 that measures burn length, flame time, and drip flame time. It’s how a material earns its rating.
The burn certificate is the proof
The burn certificate is the document that proves the material was tested to and meets FAR 25.853A. The test is the event; the certificate is the evidence — and the evidence is what ends up in your file.
What your A&P or IA actually needs
For sign-off, your mechanic needs the documentation, not a verbal assurance: the manufacturer’s flammability certification tying the specific material to FAR 25.853A. That’s the paper trail behind the airworthiness determination. No certificate, no clean file.
Don’t buy material you’ll have to chase paperwork for
Plenty of suppliers sell the vinyl and leave the certificate for you to track down later. We do the opposite: every Carolyn Fabrics aviation order ships with the burn certification documentation, so your shop has it on file from day one. See our aviation vinyl page or the certified material, Spirit Millennium.
Carolyn Fabrics supplies upholstery materials and the manufacturer’s flammability (burn) certification documentation. We do not determine airworthiness. Final compliance, installation, and airworthiness determinations for your aircraft are the responsibility of the installer/owner and certifying mechanic under applicable FAA regulations.
