Proppant test results are referenced against API RP-19C standards and available public data.
Classification by color or numerical variance does not imply a level of performance. However,
coloring of standard and public data does indicate a specific range of variance of sample test
results. The numerical ranges are typical of data variance between laboratories that participate in
API round robin or performance (e.g. conductivity) evaluation. When limits (e.g. > or <) are
used, then only green or red will apply.
