HEAT RELEASE SPECIMENS
- General Rules: Common misconception the size is not 6" x 6". The common metric for all three methods below is 150mm2 . If you need inches, it is 5.94 + 0, -0.06 .
- It should be one continuous piece, It cannot be two; 75mm x 150mm laid side by side. The will cause problems with the results because the destructive nature of the test.
SMOKE DENSITY SPECIMENS
- General Rules: The size is not 3" x 3", this is a common misconception. The common metric for all three methods below is 75mm2 . If you need inches, it is 5.94 + 0, -0.06 .
- It can be made up of several pieces side by side, if the material does not come large enough. But, it must fill the entire 75mm2 area of the face (no open space).
WIRE AND CABLE SPECIMENS
- General Rules: This is not a required test by regulating civil aviation authorities. It is a test developed by the FAA but never implemented as a requirement. The OEM's have adopted the test as part of their internal certification process. The general rule is a 10' length for each sample, or 30' total for one mode (flaming or non-flaming). However for larger wires and cables, the guidance is wires larger than 16 AWG and all multi-conductor cables, the formula for quantity is 27/dia" = length in inches per mode.
- Example, cable diameter is 0.22" then 27/0.22=123" per mode (flaming/non-flaming)
