ASTM D1533 Standard Test Method for Water in Insulating Fluids by Coulometric Karl Fischer Titration

EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of ASTM D1533 testing. This testing method involves measuring the water present in insulating liquids by coulometric Karl Fischer titration.

This testing method is commonly used for test samples below 100% relative saturation of water in oil. The coulometric testing method is known for its high degree of sensitivity (typically 10 μg H2O). This testing method requires the use of equipment specifically designed for coulometric titration.

This testing method recommends the use of commercially available coulometric Karl Fischer titrators and reagents.

The electrical properties of the insulating fluid can be adversely affected by excessive water content. High water content can make a dielectric liquid unsuitable for some electrical applications due to degradation of properties such as dielectric breakdown voltage.

This test is suitable for use in acceptance specifications, process control and evaluation of the condition of dielectric fluids in use.

Values ​​specified in SI units will be considered standard. There is no other measurement unit in this standard.

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