1. Scope

1.1 This test method covers the procedure for determining the oxidative properties of hydrocarbons by differential scanning calorimetry or pressure differential scanning calorimetry 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.

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, for example, 0.1 MPa or 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 The values stated in SI units are regarded as the standard.

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.
