ASTM E2009 : 08

Standard Test Method for Oxidation Onset Temperature of Hydrocarbons by Differential Scanning Calorimetry

Standard Details

1.1 This test method describes the determination of the oxidative properties of hydrocarbons by differential scanning calorimetry or pressure differential scanning calorimetry under linear heating rate conditions and is applicable to hydrocarbons, which oxidize exothermically in their analyzed form.

1.2 Test Method A—A differential scanning calorimeter (DSC) is used at ambient pressure, of one atmosphere of oxygen.

1.3 Test Method B—A pressure DSC (PDSC) is used at high pressure, for example, 3.5 MPa (500 psig) oxygen.

1.4 Test Method C—A differential scanning calorimeter (DSC) is used at ambient pressure of one atmosphere of air.

1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
