ASTM D3694: Standard Practices for Preparation of Sample Containers and for Preservation of Organic Constituents
SDO: ASTM: ASTM International
DOD Adopted ANSI Approved Approved
These practices cover the various means of (1) preparing sample containers used for collection of waters to be analyzed for organic constituents and (2) preservation of such samples from the time of sample collection until the time of analysis.
The sample preservation practice is dependent upon the specific analysis to be conducted. See Section 9 for preservation practices listed with the corresponding applicable general and specific constituent test method. The preservation method for waterborne oils is given in Practice D3325. Use of the information given herein will make it possible to choose the minimum number of sample preservation practices necessary to ensure the integrity of a sample designated for multiple analysis. For further considerations of sample preservation, see the Manual on Water.2
The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
