ASTM D3326-07(2024) PDF
1.1This practice covers the preparation for analysis of waterborne oils recovered from water. The identification is based upon the comparison of physical and chemical characteristics of the waterborne oils with oils from suspect sources. These oils may be of petroleum or vegetable/animal origin, or both. Seven procedures are given as follows:
Sections Procedure A (for samples of more than 50 mL volume containing significant quantities of hydrocarbons with boiling points above 280 °C) 8 to 12 Procedure B (for samples containing significant quantities of hydrocarbons with boiling points above 280 °C) 13 to 17 Procedure C (for waterborne oils containing significant amounts of components boiling below 280 °C and to mixtures of these and higher boiling components) 18 to 22 Procedure D (for samples containing both petroleum and vegetable/animal derived oils) 23 to 27 Procedure E (for samples of light crudes and medium distillate fuels) 28 to 34 Procedure F (for thin films of oil-on-water) 35 to 39 Procedure G (for oil-soaked samples) 40 to 44
1.2Procedures for the analytical examination of the waterborne oil samples are described in Practice D3415 and Test Methods D3328, D3414, and D3650. Refer to the individual oil identification test methods for the sample preparation method of choice. The deasphalting effects of the sample preparation method should be considered in selecting the best methods.
1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4This 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. Specific caution statements are given in Sections 6 and 32.
1.5This 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.
