Interior Materials

[pmanton]

Hi All:

I'm looking for a bit of ground school here. If I understand this correctly, our planes had a less stringent fire resistant standard applied for selection of the materials used for seats headliners, etc. This allows us to use materials other than those specified for aircraft as long as a burn test is performed and logged.

If this is indeed true. How would I an an IA do such a test and log it? What would I use as approved data to support such a log entry?

Thanks much

CAR 3 up to ammendment 3-12

§ 3.388 Fire precautions—

[(a) Cabin interiors. Only materials which are flash resistant shall be used. In compartments where smoking is to be permitted, the wall and ceiling linings, the covering of all upholstering, floors, and furnishings shall be flame-resistant. Such compartments shall be equipped with an adequate number of self contained ash trays. All other compartments shall be placarded against smoking.


The definition of Flash and Flame resistant from section 3.1 is


(3) Flame-resistant. Flame-resistant material means material which will not support combustion to the point of propagating, beyond safe limits, a flame after the removal of the ignition source.

(4) Flash-resistant. Flash-resistant material means material which will not burn violently when ignited.
