About This Item

 

Full Description

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 Computer or electronic-based instruments, techniques, or data treatment equivalent to this test method may also be used.

Note 1 - Users of this test method are expressly advised that all such instruments or techniques may not be equivalent. It is the responsibility of the user of this standard to determine the necessary equivalency prior to use.

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

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

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

1.6 SI units are the standard.

1.7 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.
