5.1 powdery or granular material put into the sample test sample container, filled to the rim, and the container tapped several times. As the sample sink, following Continued addition of the sample, the sample piled high after trimming flattened, covering the container with a cover, hanging in the center of the oven. 5.2 The oven temperature was raised to 140 ℃, and kept 24h. Continuous recording of oven temperature and the sample temperature. 5.3 Take a side length of 100mm cube sample at 140 ℃ conditions, the first experiment to see whether the test sample within 24h Injection temperature higher than 60 ℃ phenomenon oven temperature. If it is not this phenomenon, the test was stopped. If the above phenomenon, then take the side length 25mm cube sample at 140 ℃ conditions a second experiment, the above phenomenon was observed whether the sample. 5.4 5.3 Test if the phenomenon does not appear, according to the substance during transport in different packaging conditions are selected test temperature, take the side length 100mm cube specimens continue to experiment to see whether the above phenomenon. --- If the substance to be greater than the volume of 0.45m3, less than 3m3 container transport, test temperature was 120 ℃; --- If the substance in the container volume will be less than 0.45m3 of transport, test temperature to 100 ℃.
