Oxidation Bomb for Petroleum Testing. See also Appendix X2. Modified crucible furnace with digital thermocouple readout of flask temperature at prescribed points per ASTM specifications.

The volume of the vessel used is particularly important since lower autoignition temperatures will be achieved in larger vessels. ASTM Method being used?

A hinged holder in the cover facilitates handling of the test flask. Linearized analog output permits connection to a strip chart recorder or datalogging instrument. Test Flask, mL and Thermocouples 4 The following link provides additional information from the instruction manual or original manufacturer’s brochure. No condensed phase, liquid or solid, should be present when ignition occurs.

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. Available request a quote.

Pharmaceutical laboratory apparatus stability chambers, tablet disintegration, tablet dissolution, tablet hardness, V-blenders, 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.


The autoignition s659 by a given method does not necessarily represent the minimum temperature at which a given material will self-ignite in air. 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. 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.

Vessel material can also be an important factor.
