1050 Expression of Results..........................................................................................L. Malcolm Baker
SUMMARY OF MAJOR CHANGES SINCE 2005
The Introduction now includes more information on statistics and dilution/concentration operations,
as well as an expanded glossary. Quality Assurance (1020) and Data Quality (1030) were significantly
revised to stay abreast of regulatory requirements and clarify the quality control steps considered to be
an integral part of each test method. The revisions also are intended to ensure that these sections are
consistent with newly revised Sections 2020, 3020, 4020, 5020, 6020, and 7020.
Expression of Results (1050) contains an expanded explanation of units and scientific and engineer-
ing notation, analyte nomenclature, and propagation of error. A discussion of equivalents is also new.
The table of sampling and handling requirements in Collection and Preservation of Samples (1060)
has been updated.
