DUS 2485:2022, Standard Practice for Preservation of Waterborne Oil Samples, First edition

1.1 This practice covers the preservation of waterborne oil samples from the time of collection to the time of analysis. Information is provided to ensure sample integrity and to avoid contamination and to minimize microbial degradation.

1.2 The practice is for controlled field or laboratory conditions and specifies thorough preparation of equipment and precise operation. Where these details must be compromised in a field emergency, nonstandard simplifications are recommended that will minimize or eliminate consequent errors.

Note 1—Procedures for the analysis of oil spill samples are Practices D3326, D3415, and D4489, and Test Methods D3650, D3327, D3328, and D3414. A guide to the use of ASTM test methods for the analysis of oil spill samples is found in Practice D3415. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
