SUMMARY OF MAJOR CHANGES SINCE 2005
Quality Assurance/Quality Control (2020) was significantly revised to stay abreast of regulatory
requirements and clarify the essential quality control practices for test methods in Part 2000.
Flavor Profile Analysis (2170) contains new information on method safety and selecting and training
the panel, as well as new procedures for preparing and handling glassware, addressing fatigue, and
dechlorinating samples.
The graphical and computer methods that can be used to calculate CaCO
3
saturation indices were
updated in Calcium Carbonate Saturation (2330). Salinity (2520) now allows the use of the Interna-
tional Temperature Scale of 1990 (ITS-90). The procedure for preparing the filter and its backing was
clarified in Asbestos (2570).
Also, many methods now refer users to the quality control practices that are considered to be an
integral part of the method.
