These temperatures can be expected to vary with the test pressure and oxygen concentration.
ASTM E – 14 Standard Test Method for Autoignition Temperature of Liquid Chemicals
Responsibility for extension of this test method to solids of unknown thermal stability, boiling point, or degradation characteristics rests e6599 the operator.
Right-click to open the PDF in a new window or download it: Product Description The K Autoignition Apparatus determines the lowest temperature at which the vapors of a liquid or solid chemical sample will self-ignite under prescribed laboratory conditions.
The autoignition temperature by a given method does not necessarily represent the minimum temperature at which a given material will self-ignite in air.
Furnace cover has ports for flask exterior thermocouples, and a borosilicate glass thermocouple tube is provided to assure correct positioning of the gas temperature thermocouple inside the test flask. Lab Equipment for Sale: Type text as it appears:: Link to Active This link will always route to the current Active version of the standard. Control ast has temperature controls and digital thermocouple readout with four-position selector switch. Test Flask, mL and Thermocouples 4 The following link provides additional information from the instruction manual or original manufacturer’s brochure.
Cylindrical heating chamber provides excellent radial temperature uniformity. ASTM Method being used? Pharmaceutical laboratory apparatus stability chambers, tablet disintegration, tablet dissolution, tablet hardness, V-blenders, Enter product sstmmake or model.

Adjustable mirror permits safe viewing of the flask interior during testing.
No condensed phase, liquid or solid, should be present when ignition occurs. The volume of the vessel used is particularly important since lower autoignition temperatures will be achieved in larger vessels.

Such materials will thermally degrade in the flask and the accumulated degradation astmm may ignite.

However, results of this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use. Thermocouples plug directly into the furnace control unit for quick disconnection when removing the flask. A hinged holder in the cover facilitates handling of the test flask.

Within certain limitations, this test method can also be used to determine the autoignition temperature of solid chemicals which readily melt and vaporize at temperatures below the test adtm and for chemicals that are gaseous at atmospheric pressure and temperature. Linearized analog output permits connection to a strip chart recorder or datalogging instrument. For such materials, ignition is dependent upon the thermal and kinetic properties of the decomposition, the mass of the sample, and the heat transfer characteristics of the system.
