9. Report
9.1 Report the following information:
9.1.1 Sample Identification.
9.1.2 Identify the sample as "As Received" or "After Being Processed by Clay Treatment".
9.1.3 Sparging gas.
9.1.4 Volume concentration in the insulating liquid, of each component gas, expressed in parts per million at STP (0°C and 760 torr).
10. Precision and Bias
