This practice describes the procedure for obtaining a sample of pressurized gas for gas analysis from a system or component. A sample pressure vessel shall be evacuated and sealed with a minimum vacuum pressure. The vessel shall then be attached to the designated pressurized sample port. The pressurized gas is allowed to enter the sample vessel until the pressure is equal to the pressure of the system or component. The pressure shall be secured and the sample vessel assigned for appropriate analysis. The apparatus shall consist of connecting lines, miscellaneous fittings, tie-downs, and a gas sample vessel.
