ASTM D8072-17 PDF

1.1 This classification identifies a concise code which can be used by imaging instruments for reporting of solid particles and insoluble water content in hydrocarbon-based petroleum products. The coding system includes the reporting of water content and particle counts in the ≥1 µm range.

1.2 It is valid for imaging instruments measuring particle size by projected equivalent particle diameter (see 3.1.1), and which are calibrated and verified using particle size and count standards traceable to NIST.2

1.3 Due to the variation of method and instrument types and resolutions, the reporting of results will include the ASTM standard used to conduct the analysis.

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

1.5 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.

1.6 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.
