the sampling apparatus, sampled fluid, or the equipment to be used in
processing the sample, or both.
7. Preparations of Apparatus and Reagents
7.1 Apparatus used in this practice shall be prepared by a
reliable process for assurance of essentially contamination-free
surfaces.
NOTE 3—It is recommended that a process shall be used as described in
Test Method D4898 or Practice F311.
7.2 Reagents used in this practice shall be suitably filtered
and stored to maintain a level of refinement equivalent to the

8. Procedure
8.1 Select at random representative containers of fluid to be
sampled. When defined, selection shall be as required by the
test method.Asuggested cube-root sampling quantity is shown
