ASTM D1364 is the ASTM standard for determining water in volatile solvents using the Karl Fischer reagent titration method. It provides a consistent approach for measuring trace moisture in solvents where water content can affect performance, purity, and test results. As a technical reference, it supports quality control and product evaluation by helping laboratories and buyers apply a recognized method for moisture determination in volatile solvent materials.

ASTM D1364 standard overview

The ASTM D1364 standard focuses on water measurement in volatile solvents by Karl Fischer titration, a widely used analytical technique for moisture determination. Its main purpose is to guide a repeatable test method that can be used when accurate water content results are needed for solvent handling, specification checks, or incoming inspection. The standard is especially relevant when low-level moisture can influence product behavior, stability, or compliance with technical requirements.

Where is ASTM D1364 used?

This standard is commonly used in laboratory testing and quality assurance settings where volatile solvents are evaluated for water content. It may be applied during raw material inspection, batch release testing, or routine monitoring of solvent quality. Because the method is based on Karl Fischer reagent titration, it is suited to analytical workflows that require controlled, reproducible moisture measurement in solvent samples used for industrial, manufacturing, or research purposes.

Practical importance of ASTM D1364

ASTM D1364 matters because water content can materially affect solvent performance and downstream processes. Using a recognized test method helps reduce disagreement between suppliers and purchasers, improves consistency across laboratories, and supports more reliable procurement decisions. For organizations that manage solvent specifications or perform analytical testing, the standard can be an important tool for compliance, risk reduction, and routine quality control. ASTM D1364 also helps align testing practices with an established industry method.
