See Figure 4 for unacceptable test specimen. 3.5.3 Poke Testing 100 N min Test Method: 1) Cut five 150 mm by 150 mm samples from the footwell area. Remove all insulator from backing.
11、 2) Mount sample on a 150 mm by 150 mm platform with a 24 mm diameter hole at the center. 3) Clamp sample down using a 150 mm by 150 mm square retainer with a 24 mm diameter hole at the center. 4) Using an Instron, penetrate sample with a 6 mm diameter flat-headed pin at a standard speed of 25 mm/mi
12、n (1 in/min). Use a locator to ensure the pin is centered over the 24 mm hole. 5) Measure load when sample is penetrated, i.e. the pin goes completely through the sample. See Figures 5, 6, and 7 for test apparatus. 3.6 ENVIRONMENTAL TESTING 3.6.1 Short Term Heat, Humidity, and Cold Cycle Rating 4 mi
