Standard Classification for Reporting Solids and Insoluble Water Contamination of Hydrocarbon-Based Petroleum Products When Analyzed by Imaging Instrumentation

Importancia y uso:

4.1 The purpose of this code is to simplify the reporting of solid particle counts and water droplet concentrations present in petroleum products when measured by imaging instruments. Industry is accustomed to using a three number code to report contamination levels and so this reporting method for imaging instruments is presented to organize results in a similar format.

4.2 Particle count results as described by this classification are reported per the preferred number ranges in Table 1. Preferred numbers were originally developed by Charles Renard and codified in ISO 3. This format is the preferred reporting format since ISO 4406 has no ability to report water.

4.3 Imaging instruments are capable of identifying insoluble water droplets separate from solids, and therefore a suffix code is added after the three (or four) solid particle codes to report water content in μL/L. To report water content, detected droplets will be converted to μL/L. The distribution of water droplet size may be reported if it is useful, but it is not required.
