Results of each individual test specimen shall be determined as a mean average of the high and low values indicated on the chart. 3.14 FLAMMABILITY In order to comply with Federal Motor Vehicle Safety Standard No. 302, the materials, portions of components, and composites shall not burn, or transmit a flame across its surface, at a rate of more than 100 mm per min. To demonstrate compliance, the sample size and method of testing shall be in accordance with FLTM BN 024-02.
