1) Elasticity, solubility, inflammability are paradigm cases of dispositions in natural objects.

2) Used for testing horizontal inflammability of various fabric, which is expressed with flame - spread rate.

3) Its inflammability is accord with requirement, and has high precision.

4) The hydrocarbon oil composition is improved in safety such as volatility, inflammability, odor and skin irritation as well as working environment, and performs many functions.

5) Polystyrene burns easily but slowly, with development of thick sooty smoke. Inflammability can be reduced by addition of special additives.
