ASTM D2780 Test Method for Solubility of Fixed Gases in Liquids
11. Report
11.1 Report the solubility of a gas in a liquid sample expressed as the Ostwald coefficient. Indicate the temperature and pressure at which the liquid was saturated with the gas.
11.2 If the method has been used to determine the concentration of gas in a gas-liquid solution which is not saturated, indicate that fact, and report the Ostwald coefficient.
11.3 If the solubility of concentration of a gas in an unsaturated solution is to be reported as a Bunsen coefficient, that fact should be clearly stated in the report.
12. Precision and Bias
12.1 Because of the complex nature of Test Method D2780 for solubility of fixed gases in liquids, there is not a sufficient number of volunteers to permit a cooperative laboratory program for determining the precision and bias. If the necessary volunteers can be obtained, a program will be undertaken at a later date.
