ASTM E203 Standard Test Method for Water Using Volumetric Karl Fischer Titration

EUROLAB laboratory provides testing and compliance services within the scope of ASTM E203 standard. This test method is designed as a general guideline for the application of volumetric Karl Fischer (KF) titration to determine free water and water of hydration in most solid or liquid organic and inorganic compounds.

This test method is designed for use with automated titration systems that can potentiometrically determine the end point of the KF titration.

Samples that are gaseous at room temperature are not covered. This test method involves the use of both pyridine and pyridine-free KF reagents to determine water by volumetric titration.

The determination of water using KF coulometric titration is not discussed. With proper selection of sample size, KF reagent concentration and apparatus, this test method is suitable for measuring water in a wide concentration range, i.e. parts per million to pure water.

Values ​​stated in SI units should be accepted as standard.

This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.
