Testing StonePly: Lightweight natural stone for private jets and commercial aircraft interiors

About StonePly for Airplane Interiors

Designers, manufacturers and outfitters of custom airplane interiors for private and corporate jets have found Stone Ply to be a useful way to introduce the luxury and high-end appeal of stone to their projects. StonePly is real natural stone, granite, marble, limestone or onyx on an aluminum honeycomb backing. StonePly offers a lightweight, strong and attractive real stone finish for airplane galleys, lavatories, flooring and tables. In addition to the beauty and uniqueness of natural stone panels for aircraft interiors, StonePly also offers custom marble and granite medallions, logos and emblems for use on floors, tables and partitions.

Testing StonePly for Aircraft Interiors

The U.S. Department of Transportation Federal Aviation Administration (FAA) requires certain materials be fire tested.  This page is a brief summary of StonePly’s test results and flame resistance abilities.  For additional information on testing of aircraft materials, refer to the “Aircraft Materials Fire Test Handbook” for a description of all FAA-required fire test methods for aircraft materials.

Fire Resistance of StonePly Lightweight Stone Panel for Aircraft Interiors

StonePly offers designers of aircraft interiors a non-flammable panel made up of a thin stone face bonded to a non-flammable aluminum honeycomb backing panel with a thin layer of high strength epoxy.

Vertical Bunsen Burner Test for Cabin and Cargo Compartment Materials 

Airplane Interior Test: Vertical Bunsen Burner Test for Cabin and Cargo Compartment Materials

Result: Passed

StonePly meets or exceeds the requirements of the test.  The tested StonePly aluminum honeycomb backed stone panels:

• Did not ignite
• Did not flame
• Did not drip
• Did not spread flame

Scope:

This is a test for airplane interior finishes. This FAA test method is intended for use in determining the resistance of materials to flame when tested according to the 60-second and 12-second Vertical Bunsen Burner Tests specified in Federal Aviation Regulation (FAR) 25.853 and FAR 25.855.

Samples were 3/4″ StonePly (1/4″ stone face and 1/2″ aluminum honeycomb), 3″ by 12″ samples.  

• Two samples of marble on aluminum honeycomb panels
• Two samples of granite on aluminum honeycomb panels

The StonePly stone panels were exposed to the flame from a 3/8-inch Bunsen burner with a 1550°F minimum flame temperature for 60 seconds.

Result:

No sample ignition, flaming, dripping or spread of flame.

The StonePly stone/aluminum honeycomb panel did not ignite, flame, drip or spread flame.

Airplane Interior Test: 45-Degree Bunsen Burner Test for Cargo Compartment Liners and Waste Storage Compartment Materials

Result: Passed

This is a test for airplane interior finish materials use in cargo compartments. It is a similar test to the vertical test listed above, except for the angle of the panel. StonePly stone panels meet or exceeds the requirements of the 45-Degree Bunsen Burner Test. Both granite on aluminum honeycomb and marble on aluminum honeycomb panels were tested. When tested, StonePly panels:

• Did not burn
• Flame did not penetrate any of the specimens
• Glow time of less than 1.5 seconds  (Less than the 10 second standard to pass)

Airplane Interior Test: Horizontal Bunsen Burner Test for Cabin, Cargo Compartment, and Miscellaneous Materials

Result: Passed.

This test method is intended for use in determining the resistance of materials to flame when tested according to the 15-second horizontal Bunsen burner tests specified in FAR 25.853. In this test, materials for airplane interiors are subjected to the flame of a Bunsen burner. Both StonePly granite on aluminum honeycomb and StonePly marble on aluminum honeycomb panels were tested.

Burn Rate: 0

• Did not ignite
• Did not flame
• Did not drip
• Did not spread flame
