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 These temperatures can be expected to vary with the test pressure and oxygen concentration.

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. Vessel material can also be an important factor. Enter product namemake or model.

Test Flask, mL and Thermocouples 4 The following link provides additional ee659 from the instruction manual or original manufacturer’s brochure. 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.


No condensed phase, liquid or solid, should be present when ignition occurs. Request a Free Quote Right Now.

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 6e59 test temperature and for chemicals that are gaseous at atmospheric pressure and temperature.

A hinged holder in the cover facilitates handling of the test flask. Control panel has temperature controls and digital aztm readout with four-position selector switch. Furnace cover has ports for flask exterior thermocouples, and a borosilicate glass thermocouple tube is provided to axtm correct positioning of the gas temperature thermocouple inside the test flask.

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.

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

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

Cylindrical heating chamber provides excellent radial temperature uniformity. Responsibility for extension of this test method to solids of unknown thermal stability, boiling point, or degradation characteristics rests with the operator.

Thermocouples plug directly into the furnace control unit for quick disconnection when removing the flask. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The autoignition temperature by a given method does not necessarily represent the minimum temperature at which ashm given material will self-ignite in air. Such materials will thermally degrade in the flask and the satm degradation products may ignite.
