Standard Practice for Ampulization and Storage of Gasoline and Related Hydrocarbon Materials

Importancia y uso:

5.1 Ampulization is desirable in order to minimize variability and maximize the integrity of calibration standards or RMs, or both, being used in calibration of analytical instruments and in validation of analytical test methods in round-robin or interlaboratory cross-check programs. This practice is intended to be used when the highest degree of confidence in integrity of a material is desired.

5.2 This practice is intended to be used when it is desirable to maintain the long term storage of gasoline and related liquid hydrocarbon RMs, controls, or calibration standards for retain or repository purposes.

5.3 This practice may not be applicable to materials that contain high percentages of dissolved gases, or to highly viscous materials, due to the difficulty involved in transferring such materials without encountering losses of components or ensuring sample homogeneity.
