About This Item
ASTM D4698 is the Standard Practice for Total Digestion of Sediment Samples for Chemical Analysis of Various Metals, and it provides a controlled approach for preparing sediment for metal analysis. It is intended to support consistent sample preparation before chemical testing, helping laboratories obtain results that are more comparable across projects and methods. For organizations working with sediment data, this standard can be an important reference for reliable preparation, quality control, and more defensible analytical outcomes.
ASTM D4698 standard overview
The ASTM D4698 standard addresses total digestion of sediment samples, which is a key preparation step before determining various metals by chemical analysis. As a practice standard, it focuses on how sediment samples are processed so the material is ready for subsequent testing. This makes the document especially relevant where consistent digestion is needed to support analytical work, reporting, and method alignment. It is a practical technical reference for laboratories that prepare sediment samples for metals testing.
Where is ASTM D4698 used?
ASTM D4698 is commonly used in laboratory workflows that involve sediment sampling and chemical analysis of metals. It is relevant wherever sediment specimens must be digested in a repeatable way before testing, such as in environmental analysis, site investigations, or related quality control programs. The standard is especially useful in settings where sample preparation needs to be consistent across multiple analyses, instruments, or reporting requirements.
Practical importance of ASTM D4698
This standard matters because sample digestion can strongly affect the quality and comparability of metal analysis results. By following a recognized ASTM practice, laboratories can help improve consistency in preparation, reduce procedural variation, and support more dependable data review. For procurement, compliance, and technical evaluation, ASTM D4698 offers a common reference point that can help reduce uncertainty in sediment testing workflows and improve confidence in reported results.
