Standard Test Method for Autoignition Temperature of Liquid Chemicals
Historical Version s – view previous versions of standard Translated Version s: Adjustable mirror permits safe viewing of the flask interior during testing.
Linearized analog output permits connection to a strip chart recorder or datalogging instrument. Such materials will thermally degrade in the flask and the accumulated degradation products may ignite. See also Appendix X2. For such materials, ignition is dependent upon the thermal and kinetic properties of the decomposition, satm mass of the sample, and the heat transfer characteristics of the system.
Vessel material can also be an important factor.
Type text as it appears:: 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.

However, results of this test may be used as elements of a e65 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.
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 aztm temperature and for chemicals that are gaseous at atmospheric pressure and temperature.
No condensed phase, liquid or solid, should be present when ignition occurs.
ASTM E – 14 Standard Test Method for Autoignition Temperature of Liquid Chemicals
Pharmaceutical laboratory apparatus stability chambers, tablet disintegration, tablet dissolution, tablet hardness, V-blenders, Responsibility for extension of this test method to solids of unknown thermal stability, boiling point, or degradation characteristics rests with the operator. A hinged holder in the cover facilitates handling of the test flask. Oxidation Bomb for Petroleum Testing. Available request a quote. The autoignition temperature by a given method ast, not necessarily represent the minimum temperature at which a given material will self-ignite in air.
Koehler K47000 Auto-ignition Apparatus for Petroleum Testing
Test Flask, mL and Thermocouples 4 The following link provides additional information from the instruction manual or original manufacturer’s brochure. The volume of the vessel used is particularly important since lower autoignition temperatures will be achieved in larger vessels.
Cylindrical heating chamber provides excellent radial temperature uniformity. Email Us or call toll-free: Lab Equipment for Sale: Thermocouples plug directly into the furnace control unit for quick disconnection when removing the flask.
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 Modified crucible furnace with digital thermocouple readout of flask temperature at prescribed points per ASTM specifications.
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.
These temperatures can be expected to vary with the test pressure and oxygen concentration.
What are your requirements. Control panel has temperature controls and digital thermocouple readout with four-position selector switch. Link to Active This link will always route to the current Active version of the standard.
