ASTM D8149-20

Standard Practice for Optimization, Calibration, and Validation of Ion Chromatographic Determination of Heteroatoms and Anions in Petroleum Products and Lubricants

2020-07-22 /Active
Significance and Use:

7.1 Accurate elemental analysis of petroleum products and lubricants is necessary for the determination of chemical properties, which are used to establish compliance with commercial and regulatory specifications.

7.2 Ion chromatography is often used in cases where anion content of the material is desired. Some of the hetero-atoms can be converted by combustion in an oxygen atmosphere followed by aqueous dissolution to convert them into anions before ion chromatographic determination. A number of ion chromatographic ASTM standards issued are listed in Section 2. Of these, the D02, D05, and D16 Committee standards which use ion chromatography are listed in Table 1.


1.1 This practice covers the information on calibration, quality control, and operational guidance for anionic measurements using ion chromatography (IC).

1.2 IC Related Standards—Chemically or electrolytically regenerated suppressed ion chromatography standards for aqueous matrices include Test Methods D2988, D4327, D5085, D5542, D5827, D5987, D5996, D6581, D7319, D7328, D7359, D7773, D7994, and D8150; IC instrumentation requirements are described in Practices E1151, and E1511.

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

1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
