scope:

Specifies a laboratory method for determining the flash-ignition temperature and spontaneous-ifnition temperature of plastics using a hot-air furnace. It is one of a number of methods in use for evaluating the resistance of plastics to effects of hifg temperatures. This method does not give a direct measure of the combustibility or rate of burning of a material or any definition of the safe upper limit of temperature for the plastics in use, and it should not be used to describe or appraise the fire hazard of fire risk of materials, products or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire-hazard or fire-risk assessment which take into account all of the factors pertinent to an assessment of the fire hazard of a particular end use.
