ASTM E – 14 Standard Test Method for Autoignition Temperature of Liquid Chemicals
Product Description The K Autoignition Apparatus determines the lowest temperature asrm which the vapors of a liquid or solid chemical sample will self-ignite under prescribed laboratory conditions. 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.
Modified crucible furnace with digital thermocouple readout of flask temperature at prescribed points per ASTM specifications. Such materials will thermally degrade in the flask and the accumulated degradation products may ignite.
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 Historical Version s – view previous versions of standard.
Adjustable mirror permits asstm viewing of the flask interior during testing. Linearized analog output permits connection to a strip chart recorder or datalogging instrument. Petroleum Products and Biofuel lab apparatus baths, calorimeters, color measurement, density meters, flash point, hydrogenators, oil testing, penetrometers, surface tension, vapor pressure, viscometers and rheometers, Link to Active W659 link will always route to the current Active version of the standard.
Vessel material can also be an important factor. The autoignition temperature by a given method does not necessarily represent the minimum temperature at which a given material will self-ignite in air.

Responsibility for extension of this test method 6e59 solids of unknown thermal stability, boiling point, or degradation characteristics rests with the operator. Historical Version s – view previous versions of standard Translated Version s: What are your requirements. Oxidation Bomb for Petroleum Testing. Furnace cover has ports for flask exterior thermocouples, e6659 a borosilicate glass thermocouple tube is provided to assure correct positioning of the gas temperature thermocouple inside the test flask.
The volume of the vessel used is particularly important since lower autoignition temperatures will be achieved in larger vessels.
These temperatures can be expected to vary with the test pressure and oxygen concentration. 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.
