ASTM Method being used?
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 temperature and for chemicals that are gaseous at atmospheric pressure and temperature.

ASTM E – 15 Standard Test Method for Autoignition Temperature of Chemicals
Thermocouples plug directly into the furnace control unit for quick disconnection when removing the flask. These temperatures can be expected to aztm with the test pressure and oxygen concentration. General Use laboratory apparatus balances, baths, blenders, centrifuges, chart recorders, freezers, fume hoods, furnaces, glassware washers, glove boxes, mixers, moisture testing, ovens, pumps, shakers, vacuum equipment, water purification Enter product namemake or model.

Koehler K Auto-ignition Apparatus for Petroleum Testing (ASTM E) | Labequip
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. Pharmaceutical laboratory apparatus stability chambers, tablet disintegration, tablet dissolution, tablet hardness, V-blenders, Request a Free Quote Right Now.
However, results of this test may be used as elements of qstm 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. Available request a quote. Vessel material can also be an important factor. Test Flask, mL and Thermocouples 4 The following link provides additional information from the instruction manual or original manufacturer’s brochure.
Responsibility for extension of this test method to solids of unknown thermal stability, boiling point, or degradation characteristics rests with the operator.
Such materials will thermally degrade in the flask and the accumulated degradation products may ignite. Control panel has temperature controls and digital thermocouple readout with four-position selector switch.
Standard Test Method for Autoignition Temperature of Liquid Chemicals
The autoignition temperature by a given method does not necessarily represent the asfm temperature at which a given material will self-ignite in air. 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.
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. Referenced Documents purchase separately E6559 documents listed below are referenced within the subject standard but are not provided as part of the standard.
The volume of the vessel used is particularly important since lower autoignition temperatures will be achieved in larger vessels. Cylindrical heating chamber aatm excellent radial temperature uniformity.
