Cylindrical heating chamber provides excellent radial temperature uniformity. No condensed phase, liquid or solid, should be present when ignition occurs.

Standard Test Method for Autoignition Temperature of Liquid Chemicals

Modified atsm furnace with digital thermocouple readout of flask temperature at prescribed points per ASTM specifications. Right-click to open the PDF in a new window or download it: These temperatures can be expected to vary with the wstm pressure and oxygen concentration. Thermocouples plug directly into the furnace control unit for quick disconnection when removing the flask. The autoignition temperature by a given method does not necessarily represent the minimum temperature at which a given material will self-ignite in air.

Link to Active This link will always route to the current Active version of the standard. 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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.


Pharmaceutical laboratory apparatus stability chambers, tablet disintegration, tablet dissolution, tablet hardness, V-blenders, The volume of the vessel used is particularly important since lower autoignition temperatures will be achieved in larger vessels.

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. Historical Version s – view previous versions of standard Translated Version s: Responsibility for extension of this test method to solids of unknown thermal stability, boiling point, or degradation characteristics rests with the operator.

Lab Equipment for Sale: Vessel material can also be an important factor. Such materials will thermally degrade in the flask and the accumulated degradation products may ignite. 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.

Control panel has temperature controls and digital thermocouple readout with four-position selector switch.

ASTM E – 15 Standard Test Method for Autoignition Temperature of Chemicals

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.

Type text as it appears:: Oxidation Bomb for Petroleum Testing.

Adjustable mirror permits safe viewing of the flask interior during testing. A hinged holder in the cover facilitates handling of the test flask.
