Koehler K Auto-ignition Apparatus for Petroleum Testing (ASTM E) | Labequip

Adjustable mirror permits safe viewing of the flask interior during testing. Type text as it appears:: Cylindrical heating chamber provides excellent radial temperature uniformity. 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.

Oxidation Bomb for Petroleum Testing.

Such materials will thermally degrade in the flask and the accumulated degradation products may ignite. Historical Version s – view previous versions of standard Translated Version s: Historical Version s – view previous versions of standard.

The autoignition temperature by a given method does not necessarily represent the minimum temperature aastm which a given material will self-ignite in air.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Vessel material can also be an important factor.

ASTM Method being used? Control panel has temperature controls and digital thermocouple readout with four-position selector switch. 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.

A hinged holder in the cover facilitates handling qstm the test flask. Test Flask, mL and Thermocouples 4 The following link provides additional information from the instruction manual or original manufacturer’s brochure.

Standard Test Method for Autoignition Temperature of Liquid Chemicals

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.


For such materials, ignition is dependent upon the thermal and kinetic e569 of the decomposition, the mass of the sample, and the heat transfer characteristics of the system. Link to Active This link will always route to the current Active version of the standard.

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

The volume of the vessel used asym particularly important since lower autoignition temperatures will be achieved in larger vessels. No condensed phase, liquid or solid, should be present when ignition occurs.

Responsibility for extension of this test method to solids of unknown thermal stability, boiling point, or degradation characteristics rests with the operator. Linearized analog output permits connection to a strip chart recorder or datalogging instrument. Email Us or call toll-free:
