Is there a seat burn test by similarity for leather?
Unlike the common seat burn test by similarity for upholstery, an analogous test for leather is not practicable. This is what the Federal Aviation Administration FAA says in its Advisory Circular 25.853-1, “Flammability Requirements for Seat Cushions,” Section 5.d.1: (…) Due to the severe shrinking and unpredictable distortion experienced by leather dress cover materials, similarity approvals for leather are not recommended. Another factor to be considered is the tanning and dyeing process. Even if the same grade of leather is used for the renewal of upholstery, our experience with seat manufacturers confirms that a new seat burn test is required if the customer chooses a different color.
