This document is not anASTM standard and is intended only to provide the user of anASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

response and freedom from carryover.

verification check solution (CCV)—in methods of chemical analysis, a standard solution (or set of solutions) used to verify
freedom from excessive instrument drift; the concentration is to be near the midrange of a linear curve.

individual lot of materials conforms to the purchase order or contract or to determine the degree of uniformity of the material
supplied by the vendor, or both.

verification check solution (ICV)—in methods of chemical analysis, a standard solution (or a set of standard solutions) used to verify calibration
standard levels; the concentration of analyte is to be near mid-range of the linear curve that is made from a stock solution having a different
manufacturer or manufacturer lot identification than the calibration standards.
accountability—a term used to designate the internal control system used for nuclear materials, but does not include physical
protection. linear range check solution (LRS)—in methods of chemical analysis, a solution containing known concentrations of
the analytes that is used to determine the upper limit of the linear range.
