ASTM D5761 : 96(2006)

Standard Practice for Emulsification/Suspension of Multiphase Fluid Waste Materials

Standard Details

1.1 This practice covers the generation of a single-phase suspension or emulsion from multiphase samples which are primarily liquid in order to facilitate sample preparation, transfer, and analysis.

1.2 This practice is designed to keep a multiphase fluid sample in an emulsified/suspended state long enough to take a single, composite sample that is representative of the sample as a whole. The sample may reform multiple layers after standing.

1.3 The emulsion/suspension generated by following this practice can be used only for analytical procedures designed for the total sample and procedures not significantly affected by the emulsifier or the presence of an emulsion/suspension.

1.4 This practice assumes that a representative sample of not more than one litre has been obtained.

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

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.
