SUMMARY OF MAJOR CHANGES SINCE 2005
Quality Assurance/Quality Control (5020) was significantly revised to stay abreast of regulatory
requirements and clarify the essential quality control practices for test methods in Part 5000. Additional
sampling, filtering, and storage requirements were added to UV-Absorbing Organic Constituents
(5910).
Also, many methods now refer users to the quality control practices that are considered to be an
integral part of the method.
