About This Item
ASTM E1064 is the ASTM standard for determining water in organic liquids by coulometric Karl Fischer titration. It provides a focused test method for measuring trace moisture content in liquid organic materials where water control can affect quality, stability, and performance. As a technical document, it helps laboratories and buyers apply a consistent approach to moisture testing, supporting reliable results for product evaluation, specification checks, and routine quality control.
ASTM E1064 standard overview
The ASTM E1064 standard outlines a test method built around coulometric Karl Fischer titration, a widely used analytical technique for water determination. Its purpose is to measure water content in organic liquids with a controlled, repeatable procedure that supports laboratory consistency. The standard is especially relevant when accurate moisture measurement is needed for acceptance testing, process monitoring, or compliance with internal specifications. ASTM E1064 is a practical reference for aligning testing practices with a recognized ASTM method.
Where is ASTM E1064 used?
This standard is commonly used in laboratories that test organic liquids for moisture content, including quality control and analytical testing environments. It may be applied to incoming materials, finished liquids, or in-process samples where water levels need to be verified. ASTM E1064 is also useful for organizations that rely on coulometric Karl Fischer titration equipment and need a standardized method for generating comparable results across batches, instruments, or facilities.
Practical importance of ASTM E1064
In practice, this standard helps reduce uncertainty in water measurement and supports more consistent test reporting. Using ASTM E1064 can improve procurement decisions, release testing, and internal quality checks by giving stakeholders a recognized method for evaluating moisture in organic liquids. It also helps limit disputes by providing a common technical basis for results, especially when water content is a critical property for product performance, storage stability, or specification compliance.
