No. It measures free water and emulsified water. Dissolved water (below the saturation point) is not detected. For that, use Karl Fischer titration.

ASTM D95 does not exist in isolation; several other ASTM standards are closely related. Understanding these standards can provide a more complete picture of the testing landscape. Astm D95 Pdf
Before starting, ensure all glassware is washed, rinsed with acetone, and dried completely to prevent cross-contamination.
While you may find older, unofficial versions of the standard for free on file-sharing websites, it is a legal and professional best practice to from authorized sources. For that, use Karl Fischer titration
Free downloads found on unauthorized file-sharing websites may contain outdated versions, missing pages, or altered equations, which can lead to compliance failures during laboratory audits.
While the ASTM D95 method is a well-established workhorse, it is essential to understand its strengths and weaknesses for appropriate application. Before starting, ensure all glassware is washed, rinsed
Understanding ASTM D95: The Standard Test Method for Water in Petroleum Products and Bituminous Materials by Distillation
Typically 30 minutes to 2 hours, depending on the sample’s viscosity and water content.
is the international standard for determining water content in petroleum products, tars, and other bituminous materials through a distillation method 分析测试百科网 Core Function & Scope
The ASTM D95 test provides a simple, reproducible, and field-friendly method to quantify this contamination.
