4、 samples. Apply a 305 x 305 mm platen weighing 0.23 kg to the five plied samples. Measure the height of the pile, at the center of the vertical sides. (The average of these readings is the initial thickness of the pile (T). Apply a 2.3 kg load to the center of the pile and measure again for average

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.
