Standard Test Method for Determining Oxidation Induction Time of Hydrocarbons by Differential Scanning Calorimetry
 N E1858

Annotation

This test method describes the determination of the oxidative properties of hydrocarbons by differential scanning calorimetry or pressure differential scanning calorimetry and is applicable to hydrocarbons that oxidize exothermically in their analyzed form.

Test Method A— A differential scanning calorimeter (DSC) is used at ambient pressure, for example, about 100 kPa of oxygen.

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

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

This test method is related to ISO 11357–6 but is different in technical content. This test method is related to CEC L-85–T but includes additional experimental conditions.

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. Specific precautionary statements are given in Note 5 and Note 13.
