    Rationale

    Section 1.2 of Method D189-06 (2014) - Standard Test Method for Conradson Carbon Residue of Petroleum Products, specifies that SI units are to be regarded as standard and that no other units of measurement are included in the standard. Section 8.1 directs that the sample be filtered through a 100-mesh screen. However, mesh is not an official SI unit. Despite extensive research no rationale was found for the addition of the filter step. The test precision statement was written when no filtration step was included in the method, so to align the test method with the precision statement, it should be removed.
