About This Item
ASTM D7168 is the ASTM standard titled Standard Test Method for 99Tc in Water by Solid Phase Extraction Disk. It provides a structured laboratory approach for measuring technetium-99 in water using a solid phase extraction disk, helping support consistent analytical results and traceable reporting. This standard is important for laboratories and organizations that need a defined test method for water monitoring, environmental assessment, or compliance-related analysis where reliable radionuclide measurement is needed.
ASTM D7168 standard overview
The ASTM D7168 standard outlines a test method focused on determining 99Tc in water by solid phase extraction disk. As a technical document, it is intended to guide a controlled analytical workflow rather than general water testing. Its value lies in establishing a common method for sample preparation and measurement, which can improve comparability between laboratories and help reduce variation in results. For users selecting a standards document, ASTM D7168 supports method consistency and technical confidence.
Where is ASTM D7168 used?
This standard is commonly used in laboratory environments that analyze water for technetium-99, including facilities supporting environmental monitoring, radiological testing, and regulated water analysis. It is relevant wherever a defined solid phase extraction disk method is needed to process water samples for 99Tc measurement. ASTM D7168 may also be useful in quality assurance programs and in workflows that require documented test methods for sample handling, analytical verification, and reporting.
Practical importance of ASTM D7168
ASTM D7168 matters because it helps establish a repeatable method for a specialized water analysis task. Using a recognized ASTM standard can support compliance efforts, improve consistency in test results, and simplify procurement of a clearly defined technical reference. It is especially useful when laboratories need a common basis for evaluating performance, comparing results, or documenting methodology. For organizations managing water testing programs, ASTM D7168 can also help reduce uncertainty in analytical practice.
