ASTM D568：垂直放置的软质塑料燃烧速率和／或燃烧程度及燃烧时间的测试方法
ASTM D568：Standard Test Method for Rate of Burning and/or Extent and Time of Burning of Flexible Plastics in a Vertical Position

ASTM D568标准摘要
ASTM D 568 supports the sample vertically, whereas D 635 supports the sample horizontally. A flame from a Bunsen burner is exposed to a plastic test bar for 30 seconds. The sample is allowed to burn until it either extinguishes itself or burns past a gage mark (100 mm) on the bar. If the sample does not burn past the 100 mm gage mark, time and extent of burning are reported. If it burns past the gage mark, and average burn rate, in centimeters per minute, is reported. Materials that do not burn to the gage mark are said to be self-extinguishing.
